Path Traversal in Altium Enterprise Server Vault UploadController Allows Arbitrary File Write

A path traversal vulnerability exists in the Altium Enterprise Server Vault Service UploadController due to improper validation of a user-controlled path component in image upload requests. An authenticated user can supply a crafted absolute path so that the configured storage root is discarded, allowing arbitrary files to be written to any location on the server filesystem writable by the service account.




Because content-controlled files can be written to web-accessible directories, or used to overwrite application binaries or configuration files, this can be escalated to remote code execution, service takeover, or denial of service. Altium 365 cloud deployments are not affected, as the affected endpoint is not reachable and the cloud storage architecture mitigates the file-write primitive.

CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
