CVE-2011-1184  (opens in a new tab)
CWE-264  (opens in a new tab)

How to fix?

Upgrade tomcat to version 5.5.34, 6.0.33, 7.0.12 or higher.

Overview

Affected versions of this package are vulnerable to Access Restriction Bypass. The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 does not have the expected countermeasures against replay attacks, which makes it easier for remote attackers to bypass intended access restrictions by sniffing the network for valid requests, related to lack of checking of nonce (aka server nonce) and nc (aka nonce-count or client nonce count) values.
