CVE-2014-0468: Apache Configuration Vulnerability in FusionForge

Overview

The CVE-2014-0468 represents a severe vulnerability in the FusionForge software, specifically within the shipped Apache configuration. The vulnerability can result in the web server executing scripts that users have uploaded to their raw SCM (Software Configuration Management) repositories, such as SVN, Git, and Bzr. This is a serious security flaw as it potentially allows for system compromise and data leakage. Given the widespread use of FusionForge for collaborative software development projects, the implications of this vulnerability are significant and demand immediate attention.

How the Exploit Works

The vulnerability lies in the Apache server configuration shipped with FusionForge. When a user uploads a script to their raw SCM repository, the web server may erroneously execute the script. This could allow an attacker to upload malicious scripts to the repository and trigger the server to execute those scripts, leading to potential system compromise or data leakage.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited. An attacker could upload a malicious script to the repository, and the server might execute it. Note that this is a hypothetical scenario and not an actual exploit.

$ git clone https://target.example.com/user/repo.git
$ cd repo
$ echo "echo 'Compromised system'" > exploit.sh
$ git add exploit.sh
$ git commit -m "Add new script"
$ git push origin master

In this example, the ‘exploit.sh’ script is a stand-in for a potentially harmful script an attacker might upload. The server might then execute this script, leading to system compromise.
