Exploitability
| CWE ID | Description |
|---|---|
| CWE-22 | The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. |
| CWE-94 | The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a path traversal issue in the Git Service component used by Altium Enterprise Server and Altium 365. It occurs because the service accepts user-supplied file paths without proper validation during post-clone file-manipulation operations. An authenticated user with basic git access can exploit this to move arbitrary files outside the intended repository area.
By leveraging this file-move capability, an attacker can place malicious script content into directories where the service later executes it, leading to remote code execution under the Git Service account.
In multi-tenant Altium 365 environments, this vulnerability could allow attackers to access data belonging to other tenants on the same infrastructure node.
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized remote code execution on the Git Service account, which could compromise the affected system.
In multi-tenant deployments, it could lead to unauthorized access to data belonging to other tenants sharing the same infrastructure, potentially resulting in data breaches.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, upgrade Altium Enterprise Server to version 8.1.1 or later, where the issue has been fixed.
For Altium 365, the issue has been remediated at the service level, so ensure your service is up to date.
