Severity:	low
Title:	ht://Dig: Cross-site scripting vulnerability
Date:	02/13/2005
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	Architecture(s)
www-misc/htdig	< 3.1.6-r7	>= 3.1.6-r7	All supported architectures

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"
