Severity: Low
Title: ht://Dig: Cross-site scripting vulnerability
Date: February 13, 2005
Bugs: #80602
ID: 200502-16

---

Synopsis

ht://Dig is vulnerable to cross-site scripting attacks.

Background

ht://Dig is an HTTP/HTML indexing and searching system.

Affected packages

-------------------------------------------------------------------
 Package         /  Vulnerable  /                       Unaffected
-------------------------------------------------------------------

1 www-misc/htdig < 3.1.6-r7 >= 3.1.6-r7

Description

Michael Krax discovered that ht://Dig fails to validate the 'config'
parameter before displaying an error message containing the parameter.
This flaw could allow an attacker to conduct cross-site scripting
attacks.

Impact

By sending a carefully crafted message, an attacker can inject and
execute script code in the victim's browser window. This allows to
modify the behaviour of ht://Dig, and/or leak session information such
as cookies to the attacker.

Workaround

There is no known workaround at this time.

Resolution

All ht://Dig users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-misc/htdig-3.1.6-r7"
