Description

Overview

Apache Tomcat fails to properly handle cookies that contain a single quote, which may allow session hijacking.

Description

Apache Tomcat is an implementation of the Java Servlet and JavaServer Page (JSP) technologies. Apache Tomcat incorrectly treats a single quote as a cookie delimiter. This can cause the Tomcat cookie parsing mechanism to improperly handle all of the cookies in the cookie string that follow the cookie with the single quote. According to the vendor, the following versions of Apache Tomcat are affected

6.0.0 to 6.0.13 5.5.0 to 5.5.24 5.0.0 to 5.0.30 4.1.0 to 4.1.36 3.3 to 3.3.2

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.
