Apache Tomcat 7.0.x < 7.0.30 DIGEST Authentication Multiple Security Weaknesses

medium Log Correlation Engine Plugin ID 800606

Synopsis

The remote web server is affected by multiple security weaknesses

Description

Versions of Tomcat 7.0.x earlier than 7.0.30 are potentially affected by the following vulnerabilities:

 - Replay-countermeasure functionality in HTTP Digest Access Authentication tracks cnonce values instead of nonce values, which makes it easier for attackers to bypass access restrictions by sniffing the network for valid requests. (CVE-2012-5885)

 - HTTP Digest Access Authentication implementation caches information about the authenticated user, which could potentially allow an attacker to bypass authentication via session ID. (CVE-2012-5886)

 - HTTP Digest Access Authentication implementation does not properly check for stale nonce values with enforcement of proper credentials, which allows an attacker to bypass restrictions by sniffing requests. (CVE-2012-5887)

Solution

Upgrade to Apache Tomcat 7.0.30 or later.
