Synopsis

A vulnerability has been discovered in Tomcat that allows for the disclosure of sensitive information.

2. Impact Information

Background

Tomcat is the Apache Jakarta Project's official implementation of Java Servlets and Java Server Pages.

Description

Tomcat allows special characters like slash, backslash or URL-encoded backslash as a separator, while Apache does not.

Impact

A remote attacker could send a specially crafted URL to the vulnerable Tomcat server, possibly resulting in a directory traversal and read access to arbitrary files with the privileges of the user running Tomcat. Note that this vulnerability can only be exploited when using apache proxy modules like mod_proxy, mod_rewrite or mod_jk.

Workaround

There is no known workaround at this time.

Resolution
