Root Cause Analysis
The manipulation of the argument dest with an unknown input leads to a unknown weakness. Using CWE to declare the problem leads to CWE-345. The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
Impact: Impacted is integrity.
Exploit: The vendor explains: "That firmware version will only work on our hardware version v1.xR. We have already EOL that product 8 years ago and are no longer selling".
