Title: Horde and Imp File Disclosure Vulnerability
Severity: HIGH
Description:
Imp is a web-based mail interface/client, developed by members of the Horde project. Horde Application Framework provides support for dealing with things like preferences, compression, browser detection, connection tracking, etc.
A vulnerability has been discovered in Horde Imp. Due to insufficient sanity checks on user-supplied URI parameters, an attacker may be capable of viewing the contents of sensitive system files.
The problem occurs in the 'mailbox.php' script and can be exploited by specifiying a sensitive resource as the 'mailbox' URI parameter, within a malicious request. As a result, a remote attacker may be capable of accessing arbitrary system files with the privileges of the user invoking Horde Imp.
Information obtained through the exploiation of this vulnerability may aid an attacker in launching further attacks against the server.
