Name of the Vulnerable Software and Affected Versions
Altium Enterprise Server (affected versions not specified)
Description
A path traversal issue exists in the ComparisonService due to insufficient filename sanitization within the Gerber file upload APIs. An authenticated workspace user can manipulate the
Content-Disposition header in a multipart request to bypass the intended temporary upload directory and write arbitrary files anywhere on the server filesystem. This can lead to remote code execution if files are written to web-accessible directories, or result in service takeover and denial of service by overwriting application binaries or configuration files.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
