FreeBSD : tomcat -- authentication weaknesses (152e4c7e-2a2e-11e2-99c7-00a0d181e71d)
Medium Nessus Plugin ID 62884
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionThe Apache Software Foundation reports :
Three weaknesses in Tomcat's implementation of DIGEST authentication were identified and resolved :
- Tomcat tracked client rather than server nonces and nonce count.
- When a session ID was present, authentication was bypassed.
- The user name and password were not checked before when indicating that a nonce was stale.
These issues reduced the security of DIGEST authentication making replay attacks possible in some circumstances.
The first issue was identified by Tilmann Kuhn. The second and third issues were identified by the Tomcat security team during the code review resulting from the first issue.
SolutionUpdate the affected packages.
