Technical details
The vulnerability exists in menu_nat_more.asp's menu_nat_more_asp function, where unbounded sprintf and strcat operations on the "opt" parameter fail to validate input length before copying to a fixed-size stack buffer. An authenticated attacker with network access can trigger a stack-based buffer overflow by sending a POST request with an oversized payload, potentially achieving code execution; the exploit PoC has been publicly disclosed.
