24 January 2011

tomcat6 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 10.10
  • Ubuntu 10.04 LTS
  • Ubuntu 9.10


Software Description

  • tomcat6


It was discovered that Tomcat did not properly escape certain parameters in the Manager application which could result in browsers becoming vulnerable to cross-site scripting attacks when processing the output. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data (such as passwords), within the same domain.

The problem can be corrected by updating your system to the following package versions:

Ubuntu 10.10
tomcat6-admin - 6.0.28-2ubuntu1.1

Ubuntu 9.10
