Medium Severity
<VulnDiscussion>The DoD standard for authentication is DoD-approved PKI certificates. Authentication based on User ID and Password may be used only when it is not possible to employ a PKI certificate, and requires Authorizing Official (AO) approval. In such cases, database passwords stored in clear text, using reversible encryption, or using unsalted hashes would be vulnerable to unauthorized disclosure. Database passwords must always be in the form of one-way, salted hashes when stored internally or externally to the Database Management System (DBMS). To prevent the compromise of authentication information, such as passwords and PINs, during the authentication process, the feedback from the information system must not provide any information that would allow an unauthorized user to compromise the authentication mechanism. Obfuscation of user-provided information when typed into the system is a method used in addressing this risk. For example, displaying asterisks when a user types in a password or PIN, is an example of obscuring feedback of authentication information. The password requirement is applicable when caching_sha2_password, sha2_password, native_mysql, or LDAP user/password authentication is enabled. When this is the case, password-authenticated accounts can be created in, and authenticated by, the MySQL Server. Other STIG requirements prohibit the use of password-based authentication except when justified and approved. This deals with the exceptions. The mysql, mysqlsh, and other command-line tools are part of most MySQL installations. These tools can accept a plain-text password, but do offer alternative techniques. Since the typical user of these tools is a Database Administrator (DBA), the consequences of password compromise are particularly serious. Therefore, the use of plain-text passwords must be prohibited as a matter of practice and procedure.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
