AI-analyzed exploit summary This exploit demonstrates a local buffer overflow vulnerability in FlexHEX 2.71 via a crafted stream name, leveraging SEH Unicode bypass to execute arbitrary code (calc.exe). The payload includes alignment adjustments, NOP sleds, and a shellcode to trigger the exploit.
Description
FlexHEX 2.71 contains a local buffer overflow vulnerability in the Stream Name field that allows local attackers to execute arbitrary code by triggering a structured exception handler (SEH) overflow. Attackers can craft a malicious text file with carefully aligned shellcode and SEH chain pointers, paste the contents into the Stream Name dialog, and execute arbitrary commands like calc.exe when the exception handler is triggered.
