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. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a path traversal issue in the Altium Enterprise Server Collaboration Service. It occurs because the server improperly handles user-supplied filenames in the MCAD and Simulation file download processes. An authenticated user can send a collaboration message with a specially crafted filename that the server uses to build the download path without validating it. This allows the user to read arbitrary files from the server's filesystem.
How can this vulnerability impact me? :
Exploiting this vulnerability can allow an attacker to read sensitive files on the server, including the server's master configuration files that contain credentials for privileged accounts. This can lead to the attacker authenticating as a system administrator and gaining full control over the server.
