Multiple API endpoints in Bitbucket Server and Data Center can be abused with a malicious HTTP request, which lets an attacker execute arbitrary code on the Bitbucket server. Source: https://jira.atlassian.com/browse/BSERV-13438 ### Am I affected, and how do I check? Affected versions are 7.0.0 up to 7.6.17, 7.7.0 up to 7.17.10, 7.18.0 up to 7.21.4, 8.0.0 up to 8.0.3, 8.1.0 up to 8.1.3, 8.2.0 up to 8.2.2, and 8.3.0 up to 8.3.1, for both Bitbucket Server and Bitbucket Data Center. To check, compare the installed version against these ranges. Source: https://jira.atlassian.com/browse/BSERV-13438 ### What should I do about it? Upgrade to the fixed release for your branch: 7.6.17, 7.17.10, 7.21.4, 8.0.3, 8.1.3, 8.2.2 or 8.3.1. The advisory cites 7.6.17 (LTS) or newer as the fix for the 7.x line. Source: https://jira.atlassian.com/browse/BSERV-13438 ### Is it being exploited? Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-09-30, which means it has evidence of attacks. No public exploit code is tracked.
