CVE-2011-1184 is an authentication replay weakness in Apache Tomcat HTTP Digest Access Authentication. Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 do not implement the expected replay protections because they inadequately validate the server nonce and nonce-count values in Digest authentication requests. Consequently, a previously valid captured Digest-authenticated request can be accepted again rather than rejected as a replay.

An Apache Tomcat HTTP Digest Access Authentication replay-protection flaw. Insufficient validation of server nonce and nonce-count values enables a remote attacker who can sniff valid network requests to replay them and bypass intended access restrictions.
Multiple HTTP DIGEST authentication weaknesses permitting replay attacks and reducing DIGEST security to approximately that of BASIC authentication.
