Synopsis

Multiple vulnerabilities in the Horde Application Framework may lead to the execution of arbitrary files, information disclosure, and allow a remote attacker to bypass security restrictions.

2. Impact Information

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.

Description

Multiple vulnerabilities have been reported in the Horde Application Framework:

David Collins, Patrick Pelanne and the HostGator.com LLC support team discovered that the theme preference page does not sanitize POST variables for several options, allowing the insertion of NULL bytes and ".." sequences (CVE-2008-1284).
An error exists in the Horde API allowing users to bypass security restrictions.

Impact

The first vulnerability can be exploited by a remote attacker to read arbitrary files and by remote authenticated attackers to execute arbitrary files. The second vulnerability can be exploited by authenticated remote attackers to perform restricted operations.
