How the Exploit Works
The exploit works by taking advantage of the weakness in the signature validation process implemented by the Quest KACE Systems Management Appliance (SMA). The malicious user, without any authentication, can upload a backup file containing malicious content. Once uploaded, the backup file can be restored, leading to the compromise of the system integrity and potential data leakage.
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited. This is a sample HTTP request that uploads a malicious backup file to the system:
POST /backup/restore HTTP/1.1
Host: target.example.com
Content-Type: application/octet-stream
Content-Length: [length of the backup file]
[binary data of the backup file]
