Vulnerability Assessment Details

ht://Dig's htsearch potential exposure/dos

Vulnerability Assessment Summary
htsearch?-c/nonexistent

Detailed Explanation for this Vulnerability Assessment

The remote CGI htsearch permits the user to supply his own
configuration file using the '-c' switch, as in :

/cgi-bin/htsearch?-c/some/config/file

This file is not displayed by htsearch. However, if an
attacker manages to upload a configuration file to the remote
server, it may make htsearch read arbitrary files on the remote host.

A possible hacker may also use this flaw to exhaust the resources on the
remote host by specifying /dev/zero as a configuration file.

Solution: Upgrade to ht://Dig 3.1.6 or newer
(http://www.htdig.org/files/snapshots/)

Network Security Threat Level: High

Networks Security ID: 3410
