Synopsis
========

SnipSnap is vulnerable to HTTP response splitting attacks such as web
cache poisoning, cross-user defacement, and cross-site scripting.

Background
==========

SnipSnap is a user friendly content management system with features
such as wiki and weblog.

Affected packages
=================

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

Description
===========

SnipSnap contains various HTTP response splitting vulnerabilities that
could potentially compromise the sites data. Some of these attacks
include web cache poisoning, cross-user defacement, hijacking pages
with sensitive user information, and cross-site scripting. This
vulnerability is due to the lack of illegal input checking in the
software.

Impact
======

A malicious user could inject and execute arbitrary script code,
potentially compromising the victim's data or browser.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All SnipSnap users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=dev-java/snipsnap-bin-1.0_beta1"
    # emerge ">=dev-java/snipsnap-bin-1.0beta1"
