Apache mod_jk: Directory traversal

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
www-apache/mod_jk	< 1.2.23	>= 1.2.23	All supported architectures

Related bugreports: #186218

A directory traversal vulnerability has been discovered in Apache mod_jk.

2. Impact Information

Apache mod_jk is a connector for the Tomcat web server.

Apache mod_jk decodes the URL within Apache before passing them to Tomcat, which decodes them a second time.

A remote attacker could browse a specially crafted URL on an Apache server running mod_jk, possibly gaining access to restricted resources.

3. Resolution Information

There is no known workaround at this time.

All Apache mod_jk users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apache/mod_jk-1.2.23"
