Description

The remote host is affected by the vulnerability described in GLSA-200705-03 (Tomcat: Information disclosure)

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.
