Severity: High
Title: Horde Application Framework: Remote code execution
Date: April 04, 2006
Bugs: #127889, #126435
ID: 200604-02

Synopsis

The help viewer of the Horde Framework allows attackers to execute
arbitrary remote code.

Background

The Horde Application Framework is a general-purpose web application
framework written in PHP, providing classes for handling preferences,
compression, browser detection, connection tracking, MIME and more.

Affected packages

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

1 www-apps/horde < 3.1.1 >= 3.1.1

Description

Jan Schneider of the Horde team discovered a vulnerability in the help
viewer of the Horde Application Framework that could allow remote code
execution (CVE-2006-1491). Paul Craig reported that "services/go.php"
fails to validate the passed URL parameter correctly (CVE-2006-1260).

Impact

An attacker could exploit the vulnerability in the help viewer to
execute arbitrary code with the privileges of the web server user. By
embedding a NULL character in the URL parameter, an attacker could
exploit the input validation issue in go.php to read arbitrary files.

Workaround

There are no known workarounds at this time.

Resolution

All Horde Application Framework users should upgrade to the latest
version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/horde-3.1.1"
