The download commit resource in Atlassian Bitbucket Server from version 5.1.0 before version 5.1.7, from version 5.2.0 before version 5.2.5, from version 5.3.0 before version 5.3.3 and from version 5.4.0 before version 5.4.1 allows remote attackers to write files to disk potentially allowing them to gain code execution, exploit CVE-2017-1000117 if a vulnerable version of git is in use, and or determine if an internal service exists via an argument injection vulnerability in the at parameter.

Security readout for executives and security teams

Certain Atlassian Bitbucket Server 5.1 through 5.4 releases had a flaw in commit download handling that could let a remote attacker write files to disk. The source also says this could potentially lead to code execution, interact with a vulnerable Git version, or probe internal services. Exposure is limited to Atlassian Bitbucket Server deployments in the listed 5.1.x, 5.2.x, 5.3.x, and 5.4.x vulnerable ranges. Internet-facing or widely accessible Bitbucket instances would carry higher operational risk. Prioritize remediation for any exposed Bitbucket Server in the affected ranges. The business risk is elevated because the described impact includes file write and potential code execution, but the supplied sources do not show active exploitation. Mitigation focus: Upgrade Bitbucket Server beyond the affected version range.; Review Atlassian BSERV-10593 for vendor guidance and fixed release details.; Confirm the underlying Git version is not vulnerable to CVE-2017-1000117..
