How the Exploit Works

The vulnerability allows a malicious user to perform directory traversal on the Pagure server by submitting a specially crafted git repository. As a result, the attacker could gain unauthorized access to sensitive information or secrets on the server, leading to potential system compromise or data leakage.

Conceptual Example Code

A malicious user might exploit this vulnerability by sending a specially crafted git repository to the Pagure server. The following is a simplified, conceptual example of such malicious git repository:

mkdir evil_repo
cd evil_repo
git init
echo "malicious code" > ../../../../../etc/secrets
git add ../../../../../etc/secrets
git commit -m "exploit"

In this example, the malicious user is creating a git repository (`evil_repo`) containing a file that is placed outside the repository’s directory via directory traversal (`../../../../../etc/secrets`). The malicious code within this file could then be used to compromise the system or leak data.
