CVE-2010-4172: Apache Tomcat Manager application XSS vulnerability

Severity: Tomcat 7.0.x - Low, Tomcat 6.0.x - Moderate

Vendor: The Apache Software Foundation

Versions Affected: - - Tomcat 7.0.0 to 7.0.4 - Not affected in default configuration. - Affected if CSRF protection is disabled - Additional XSS issues if web applications are untrusted - - Tomcat 6.0.12 to 6.0.29 - Affected in default configuration - Additional XSS issues if web applications are untrusted - - Tomcat 5.5.x - Not affected

Description: The session list screen (provided by sessionList.jsp) in affected versions uses the orderBy and sort request parameters without applying filtering and therefore is vulnerable to a cross-site scripting attack. Users should be aware that Tomcat 6 does not use httpOnly for session cookies by default so this vulnerability could expose session cookies from the manager application to an attacker. A review of the Manager application by the Apache Tomcat security team identified additional XSS vulnerabilities if the web applications deployed were not trusted.

Example: GET /manager/html/sessions?path=/&sort="><script>alert('xss')</script>order=ASC&action=injectSessions&refresh=Refresh+Sessions+list

Mitigation: Users of affected versions should apply one of the following mitigations - - Tomcat 7.0.0 to 7.0.4 - Remove the Manager application - Remove the sessionList.jsp and sessionDetail.jsp files - Ensure the CSRF protection is enabled - Apply the patch 7.0.4 patch (see below) - Update to 7.0.5 when released - - Tomcat 6.0.12 to 6.0.29 - Remove the Manager application - Remove the sessionList.jsp and sessionDetail.jsp files - Apply the patch for 6.0.29 (see below) - Update to 6.0.30 when released

No release date has been set for the next Tomcat 7.0.x and Tomcat 6.0.x releases.

Credit: The original issue was discovered by Adam Muntner of Gotham Digital Science. Additional issues were identified by the Tomcat security team as a result of reviewing the original issue.
