CVE-2022-36525Network attack vector

Unauthenticated memory corruption via authenticationcgi_main

Published Aug 15, 2022 · Updated Aug 3, 2024

A buffer overflow in D-Link GO-RT-AC750 firmware 101b03 and 200b02 allows remote attackers to trigger memory corruption via authenticationcgi_main. The public record identifies authenticationcgi_main as the vulnerable locus but does not disclose the input field, copy operation, or missing bounds check. Network access without authentication or user interaction is sufficient, while the resulting behavior beyond memory corruption remains undisclosed.
