Title: Horde IMP Local 'prefs.lang' Vulnerability
Severity: MODERATE
Description:
IMP is a powerful 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.
If an attacker can create a file on a webserver's filesystem called 'prefs.lang' which is world readable then it may be possible for attackers to gain the privileges of the webserver process.
The contents of this file, if it exists on the webserver, can be executed by the PHP interpreter through a vulnerable website.
If custom PHP code can be executed, the privileges of the interpreter (the httpd process) can be gained.
Certain setups may make this vulnerability remotely exploitable. An example would be if the malicious file could be uploaded through a vulnerable FTP server. This may provide local access to attackers.
