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.
\nThis 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 across Altium 365 shared multi-tenant deployments at the service level; remediation is in progress on remaining Altium 365 deployments.\n\n
