|Gentoo Linux Security Advisory
Title: Horde-Chora: Remote code execution (GLSA 200406-09)
Date: June 15, 2004
Updated: December 30, 2007
A vulnerability in Chora allows remote code execution and file upload.
Chora is a PHP-based SVN/CVS repository viewer by the HORDE project.
Vulnerable: < 1.2.2
Unaffected: >= 1.2.2
Architectures: All supported architectures
A vulnerability in the diff viewer of Chora allows an attacker to inject shellcode. An attacker can exploit PHP's file upload functionality to upload a malicious binary to a vulnerable server, chmod it as executable, and run the file.
An attacker could remotely execute arbitrary binaries with the permissions of the PHP script, conceivably allowing further exploitation of local vulnerabilities and remote root access.
There is no known workaround at this time.
All users are advised to upgrade to the latest version of Chora:
|# emerge sync
# emerge -pv ">=www-apps/horde-chora-1.2.2"
# emerge ">=www-apps/horde-chora-1.2.2"
