Severity: High
Title: Horde-Chora: Remote code execution
Date: June 15, 2004
Bugs: #53800
ID: 200406-09

---

Synopsis

A vulnerability in Chora allows remote code execution and file
upload.

Background

Chora is a PHP-based SVN/CVS repository viewer by the HORDE
project.

Affected packages

---

Description

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.

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All users are advised to upgrade to the latest version of
Chora:

    # emerge sync
    # emerge -pv ">=net-www/horde-chora-1.2.2"
    # emerge ">=net-www/horde-chora-1.2.2"
