medium Log Correlation Engine Plugin ID 800606
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
