Local code execution via activation-code buffer overflow
Published Mar 24, 2026 · Updated Mar 24, 2026
Buffer overflow in Flexhex River Past Cam Do 3.7.6 allows local users to execute arbitrary code through a crafted activation code. The activation dialog accepts an overlong string that overwrites SEH control data after 608 bytes and transfers control through attacker-supplied handler values. Exploitation requires local access to paste the string and select Activate; the published payload demonstrates execution in the application's security context.
