## Symptoms

- * The Mobile Access Portal's File Share application is vulnerable to a directory traversal attack, allowing an authenticated, malicious end-user (authorized to at least one File Share application) to list the file names of 'nobody'-accessible directories on the Mobile Access gateway.

  Additionally, an authenticated, malicious end-user may create arbitrary files with 'nobody' permissions on the Mobile Access gateway's '/tmp' folder.

  Access to file contents does not seem possible via the attack described above, as the vulnerable API is capable of directory listing and file upload only.
* This issue received the ID [CVE-2024-52885](https://www.cve.org/CVERecord?id=CVE-2024-52885)
