GLSA-200705-03 : Tomcat: Information disclosure
Medium Nessus Plugin ID 25133
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
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.
There is no known workaround at this time.
SolutionAll Tomcat users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-servers/tomcat-5.5.22'
