Symbolic links must not be used in the web content directory tree.
High Severity
<VulnDiscussion>A symbolic link allows a file or a directory to be referenced using a symbolic name raising a potential hazard if symbolic linkage is made to a sensitive area. When web scripts are executed and symbolic links are allowed, the web user could be allowed to access locations on the web server that are outside the scope of the web document root or home directory. </VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance>If symbolic links are found in the web content directory tree, the target file or directory is outside of the web content directory tree, and file permissions allow the web user write authority, then the severity level will remain at CAT 1. If symbolic links are found in the web content directory tree, the target file or directory is outside of the web content directory tree, and file permissions allow the web user any authority less than write, then the severity level will be downgraded to CAT 2. If symbolic links are found in the web content directory tree, the target file or directory is not outside of the web content directory tree, and file permissions allow the web user write authority, then the severity level will remain at CAT 1.

<GroupDescription></GroupDescription>
All interactive programs (CGI) must be placed in a designated directory with appropriate permissions.
Medium Severity
<VulnDiscussion>CGI scripts represents one of the most common and exploitable means of compromising a web server. By definition, CGI are executable by the operating system of the host server. While access control is provided via the web service, the execution of CGI programs is not otherwise limited unless the SA or Web Manager takes specific measures. CGI programs can access and alter data files, launch other programs and use the network. CGI programs can be written in any available programming language. C, PERL, PHP, Javascript, VBScript and shell (sh, ksh, bash) are popular choices.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

The number of allowed simultaneous requests must be set.
Medium Severity
<VulnDiscussion>Resource exhaustion can occur when an unlimited number of concurrent requests are allowed on a web site, facilitating a denial of service attack. Mitigating this kind of attack will include limiting the number of concurrent HTTP/HTTPS requests per IP address and may include, where feasible, limiting parameter values associated with keepalive, (i.e., a parameter used to limit the amount of time a connection may be inactive).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
Each readable web document directory must contain either a default, home, index, or equivalent file.
Low Severity
<VulnDiscussion>The goal is to completely control the web users experience in navigating any portion of the web document root directories. Ensuring all web content directories have at least the equivalent of an index.html file is a significant factor to accomplish this end. Also, enumeration techniques, such as URL parameter manipulation, rely upon being able to obtain information about the web server’s directory structure by locating directories with default pages. This practice helps ensure that the anonymous web user will not obtain directory browsing information or an error message that reveals the server type and version.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
Web server administration must be performed over a secure path or at the local console.
High Severity
<VulnDiscussion>Logging into a web server remotely using an unencrypted protocol or service when performing updates and maintenance is a major risk. Data, such as user account, is transmitted in plaintext and can easily be compromised. When performing remote administrative tasks, a protocol or service that encrypts the communication channel must be used. An alternative to remote administration of the web server is to perform web server administration locally at the console. Local administration at the console implies physical access to the server. </VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

Logs of web server access and errors must be established and maintained
Medium Severity
<VulnDiscussion>A major tool in exploring the web site use, attempted use, unusual conditions, and problems are reported in the access and error logs. In the event of a security incident, these logs can provide the SA and the web manager with valuable information. Without these log files, SAs and web managers are seriously hindered in their efforts to respond appropriately to suspicious or criminal actions targeted at the web site.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

Log file access must be restricted to System Administrators, Web Administrators or Auditors.
Medium Severity
<VulnDiscussion>A major tool in exploring the web site use, attempted use, unusual conditions, and problems are the access and error logs. In the event of a security incident, these logs can provide the SA and the web manager with valuable information. To ensure the integrity of the log files and protect the SA and the web manager from a conflict of interest related to the maintenance of these files, only the members of the Auditors group will be granted permissions to move, copy, and delete these files in the course of their duties related to the archiving of these files.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
Only web sites that have been fully reviewed and tested must exist on a production web server.
Medium Severity
<VulnDiscussion>In the case of a production web server, areas for content development and testing will not exist, as this type of content is only permissible on a development web site. The process of developing on a functional production web site entails a degree of trial and error and repeated testing. This process is often accomplished in an environment where debugging, sequencing, and formatting of content are the main goals. The opportunity for a malicious user to obtain files that reveal business logic and login schemes is high in this situation. The existence of such immature content on a web server represents a significant security risk that is totally avoidable.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

Web client access to the content directories must be restricted to read and execute.
High Severity
<VulnDiscussion>Excessive permissions for the anonymous web user account are one of the most common faults contributing to the compromise of a web server. If this user is able to upload and execute files on the web server, the organization or owner of the server will no longer have control of the asset.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
A web site must not contain a robots.txt file.
Medium Severity
<VulnDiscussion>Search engines are constantly at work on the Internet. Search engines are augmented by agents, often referred to as spiders or bots, which endeavor to capture and catalog web-site content. In turn, these search engines make the content they obtain and catalog available to any public web user. To request that a well behaved search engine not crawl and catalog a site, the web site may contain a file called robots.txt. This file contains directories and files that the web server SA desires not be crawled or cataloged, but this file can also be used, by an attacker or poorly coded search engine, as a directory and file index to a site. This information may be used to reduce an attacker’s time searching and traversing the web site to find files that might be relevant. If information on the web site needs to be protected from search engines and public view, other methods must be used. </VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

A private web server must utilize an approved TLS version.
Medium Severity
<VulnDiscussion>Transport Layer Security (TLS) encryption is a required security setting for a private web server. Encryption of private information is essential to ensuring data confidentiality. If private information is not encrypted, it can be intercepted and easily read by an unauthorized party. A private web server must use a FIPS 140-2 approved TLS version, and all non-FIPS-approved SSL versions must be disabled. FIPS 140-2 approved TLS versions include TLS V1.0 or greater. NIST SP 800-52 specifies the preferred configurations for government systems. </VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

A private web server will have a valid DoD server certificate.
Medium Severity
<VulnDiscussion>This check verifies that DoD is a hosted web site's CA. The certificate is actually a DoD-issued server certificate used by the organization being reviewed. This is used to verify the authenticity of the web site to the user. If the certificate is not for the server (Certificate belongs to), if the certificate is not issued by DoD (Certificate was issued by), or if the current date is not included in the valid date (Certificate is valid from), then there is no assurance that the use of the certificate is valid. The entire purpose of using a certificate is, therefore, compromised.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
Java software on production web servers must be limited to class files and the JAVA virtual machine.
Low Severity
<VulnDiscussion>From the source code in a .java or a .jpp file, the Java compiler produces a binary file with an extension of .class. The .java or .jpp file would, therefore, reveal sensitive information regarding an application’s logic and permissions to resources on the server. By contrast, the .class file, because it is intended to be machine independent, is referred to as bytecode. Bytecodes are run by the Java Virtual Machine (JVM), or the Java Runtime Environment (JRE), via a browser configured to permit Java code.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

Anonymous FTP user access to interactive scripts is prohibited.
Medium Severity
<VulnDiscussion>The directories containing the CGI scripts, such as PERL, must not be accessible to anonymous users via FTP. This applies to all directories that contain scripts that can dynamically produce web pages in an interactive manner (i.e., scripts based upon user-provided input). Such scripts contain information that could be used to compromise a web service, access system resources, or deface a web site.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
PERL scripts must use the TAINT option.
Medium Severity
<VulnDiscussion>PERL (Practical Extraction and Report Language) is an interpreted language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information. The language is often used in shell scripting and is intended to be practical, easy to use, and efficient means of generating interactive web pages for the user. Unfortunately, many widely available freeware PERL programs (scripts) are extremely insecure. This is most readily accomplished by a malicious user substituting input to a PERL script during a POST or a GET operation. Consequently, the founders of PERL have developed a mechanism named TAINT that protects the system from malicious input sent from outside the program. When the data is tainted, it cannot be used in programs or functions such as eval(), system(), exec(), pipes, or popen(). The script will exit with a warning message. It is vital that if PERL is being used, the following line appear in the first line of PERL scripts: #!/usr/local/bin/perl –T </VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations>WG460 - General</Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl>If the TAINT option cannot be used for any reason, this finding can be mitigated by the use of a third-party input validation mechanism or input validation will be included as part of the script in use. This must be documented.</MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

The web document (home) directory must be in a separate partition from the web server’s system files.
Medium Severity
<VulnDiscussion>Application partitioning enables an additional security measure by securing user traffic under one security context, while managing system and application files under another. Web content is can be to an anonymous web user. For such an account to have access to system files of any type is a major security risk that is avoidable and desirable. Failure to partition the system files from the web site documents increases risk of attack via directory traversal, or impede web site availability due to drive space exhaustion. </VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

The required DoD banner page must be displayed to authenticated users accessing a DoD private website.
Low Severity
<VulnDiscussion>A consent banner will be in place to make prospective entrants aware that the website they are about to enter is a DoD web site and their activity is subject to monitoring. The document, DoDI 8500.01, establishes the policy on the use of DoD information systems. It requires the use of a standard Notice and Consent Banner and standard text to be included in user agreements. The requirement for the banner is for websites with security and access controls. These are restricted and not publicly accessible. If the website does not require authentication/authorization for use, then the banner does not need to be present. A manual check of the document root directory for a banner page file (such as banner.html) or navigation to the website via a browser can be used to confirm the information provided from interviewing the web staff.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

Web Administrators must only use encrypted connections for Document Root directory uploads.
High Severity
<VulnDiscussion>Logging in to a web server via an unencrypted protocol or service, to upload documents to the web site, is a risk if proper encryption is not utilized to protect the data being transmitted.

Remote authors or content providers must have all files scanned for viruses and malicious code before uploading files to the Document Root directory.
Medium Severity
<VulnDiscussion>Remote web authors should not be able to upload files to the Document Root directory structure without virus checking and checking for malicious or mobile code. A remote web user, whose agency has a Memorandum of Agreement (MOA) with the hosting agency and has submitted a DoD form 2875 (System Authorization Access Request (SAAR)) or an equivalent document, will be allowed to post files to a temporary location on the server. All posted files to this temporary location will be scanned for viruses and content checked for malicious or mobile code. Only files free of viruses and malicious or mobile code will be posted to the appropriate DocumentRoot directory.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Web Administrator</Responsibility><IAControls></IAControls>

Public web servers must use TLS if authentication is required.
Medium Severity
<VulnDiscussion>Transport Layer Security (TLS) is optional for a public web server. However, if authentication is being performed, then the use of the TLS protocol is required. Without the use of TLS, the authentication data would be transmitted unencrypted and would become vulnerable to disclosure. Using TLS along with DoD PKI certificates for encryption of the authentication data protects the information from being accessed by all parties on the network. To further protect the authentication data, the web server must use a FIPS 140-2 approved TLS version and all non-FIPS-approved SSL versions must be disabled. FIPS 140-2 approved TLS versions include TLS V1.0 or greater.
