CVE-2020-36961Public exploit

Code execution via crafted SEH overwrite

Published Jan 28, 2026 · Updated Jan 28, 2026

Stack-based buffer overflow in 10-Strike Network Inventory Explorer 8.65 allows attackers to execute arbitrary code through a crafted file. A 209-byte overwrite reaches the SEH records, replaces the next-SEH and handler pointers, and redirects control through a POP-POP-RET sequence into attacker-supplied payload bytes. Exploitation requires the crafted file to be processed on Windows and runs code with the privileges of the application user.
