Description

The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.36, 6.x before 6.0.36, and 7.x before 7.0.30 does not properly check for stale nonce values in conjunction with enforcement of proper credentials, which makes it easier for remote attackers to bypass intended access restrictions by sniffing the network for valid requests.

Affected products

Apache Tomcat: from 5.5.0 before 5.5.36; from 6.0.0 before 6.0.36; from 7.0.0 before 7.0.30 — fixed in 5.5.36, 6.0.36, 7.0.30

How to fix

Upgrade to a fixed version: Apache Tomcat 5.5.36, 6.0.36, 7.0.30. Check the vendor advisory for mitigations.
