CVE-2024-2546Network attack vector

Authenticated memory corruption via unchecked 5 GHz key

Published Mar 17, 2024 · Updated Aug 1, 2024

Stack-based buffer overflow in Tenda AC18 15.13.07.09 allows remote authenticated users to corrupt memory via a crafted 5 GHz key. The fromSetWirelessRepeat function copies attacker-controlled wpapsk_crypto5g data into a stack buffer without enforcing its capacity. Low-privilege access to the web management service is required, and no specific post-corruption outcome has been published.
