Apache Tomcat 7.0.x < 7.0.12 Multiple Vulnerabilities

medium Nessus Network Monitor Plugin ID 5882

Synopsis

The remote web server is affected by security bypass vulnerability.

Description

According to its self-reported version number, the instance of Apache Tomcat 7.x listening on the remote host is prior to 7.0.12. It is, therefore, affected by multiple vulnerabilities:

- A fix for CVE-2011-1088 introduced a security bypass vulnerability. If login configuration data is absent from the 'web.xml' file and a web application is marked as 'metadata-complete', security constraints are ignored and may be bypassed by an attacker. Please note this vulnerability only affects version 7.0.11 of Tomcat. (CVE-2011-1183)

- Several weaknesses were found in the HTTP Digest authentication implementation. The issues are as follows: replay attacks are possible, server nonces are not checked, client nonce counts are not checked, 'quality of protection' (qop) values are not checked, realm values are not checked, and the server secret is a hard-coded, known string. The effect of these issues is that Digest authentication is no stronger than Basic authentication. (CVE-2011-1184, CVE-2011-5062, CVE-2011-5063, CVE-2011-5064)

- Updates to the HTTP BIO connector, in support of Servlet 3.0 asynchronous requests, fail to completely handle HTTP pipelining. Sensitive information may be disclosed because responses from the server can be improperly returned to the wrong request and possibly to the wrong user. (CVE-2011-1475)

Note that Nessus Network Monitor has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat 7.0.12 or later.
