Summary
A path traversal vulnerability in the Git Service component of Altium Enterprise Server and Altium 365 allows an authenticated user with basic git access to move files outside the intended repository area. This can lead to remote code execution under the Git Service account by placing attacker-controlled scripts into executable directories.
Risk Assessment
The risk includes remote code execution on the server and potential access to other tenants' data in multi-tenant Altium 365 deployments, compromising confidentiality and integrity.
Recommendation
Immediately update Altium Enterprise Server to version 8.1.1 or later. For Altium 365, ensure the fix has been applied at the service level (contact your provider).
Original NVD description (English source)
A path traversal vulnerability exists in the Git Service component shared by Altium Enterprise Server and Altium 365. The service accepts a sequence of post-clone file-manipulation operations that use user-supplied paths without validation, allowing an authenticated user with basic git access to move arbitrary files outside the intended repository area. This file-move primitive can be used to place attacker-controlled script content into directories where it is later executed by the service, resulting in remote code execution under the Git Service account. On multi-tenant Altium 365 deployments, this could have allowed access to data belonging to other tenants on the same infrastructure node. Altium Enterprise Server is fixed in 8.1.1; the issue has been remediated in Altium 365 (commercial and government cloud) at the service level.
