According to the vendor, the following versions of Apache Tomcat are affected 6.0.0 to 6.0.13 |
Impact
This vulnerability can increase the possibility of a session hijacking success. In the presense of a cross-site scripting vulnerability, it may allow a denial-of-service attack against a web site by preventing a client from being able to log in using cookies. |
Solution
Apply an update This vulnerability is addressed in Apache Tomcat 6.0.14. Please check the Apache Tomcat Security page for availability of fixes for this and other versions of Tomcat. |
