Vulnerability Assessment Details

mod_jk chunked encoding DoS

Vulnerability Assessment Summary
Checks for version of mod_jk

Detailed Explanation for this Vulnerability Assessment

The remote host is using the Apache mod_jk module which
is older than version 1.2.1

There is a bug in these versions which may permit an
attacker to use chunked encoding requests to desynchronize
Apache and Tomcat, and therefore prevent the remote web site
from working properly.

*** As Nessus solely relied on the banner of the remote
*** host to issue this alert, this might be a false positive

Solution : Upgrade to mod_jk 1.2.1 or newer
Network Security Threat Level: Medium

Networks Security ID: 6320
