Medium Severity
<VulnDiscussion>When Tomcat is installed behind a proxy configured to only allow access to certain contexts (web applications), an HTTP request containing "/\../" may allow attackers to work around the proxy restrictions using directory traversal attack methods. If "allow_backslash" is "true", the "\" character will be permitted as a path delimiter. The default value for the setting is "false", but Tomcat must always be configured as if no proxy restricting context access was used, and "allow_backslash" should be set to "false" to prevent directory-traversal-style attacks. This setting can create operability issues with noncompliant clients.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
