A vulnerability in the SharedSecretClusterAuthenticator component of Atlassian Bitbucket Data Center (versions 5.14.0 and later before 7.6.14, 7.7.0 and later prior to 7.17.6, 7.18.0 and later prior to 7.18.4, 7.19.0 and later prior to 7.19.4, and 7.20.0) allows remote, unauthenticated attackers to execute arbitrary code on the server. The flaw is due to unsafe Java deserialization, which can be exploited by sending crafted serialized objects to the vulnerable endpoint.

This repository contains a Python exploit script (CVE-2022-26133.py) targeting Atlassian Bitbucket Data Center's Java deserialization vulnerability (CVE-2022-26133). The exploit allows for both verification (vulnerability check) and exploitation (arbitrary command execution) against a specified target. The script can be used in batch mode to check multiple targets or to execute supplied commands, including reverse shell payloads for both Windows and Linux. The main attack vector is network-based, connecting to the target's default port 5701. The README provides usage instructions and example payloads. No hardcoded IPs or domains are present, but the script expects the user to supply the target URL and desired command. The repository is operational and suitable for real-world exploitation, not just proof-of-concept.
