CVE-2018-8879 is a critical stack-based buffer overflow vulnerability affecting Asuswrt-Merlin firmware versions older than 384.4 and ASUS firmware versions before 3.0.0.4.382.50470, specifically impacting devices like the ASUS RT-AC66U. This flaw allows unauthenticated remote attackers to execute arbitrary code by sending a crafted, long string to the blocking.asp page via GET or POST requests, targeting parameters such as 'flag', 'mac', and 'cat_id'. With a CVSS score of 9.8 (Critical) and a FAUCET Risk Score of 96/100, the vulnerability presents a high risk due to its network-based attack vector, low attack complexity, and potential for complete compromise of confidentiality, integrity, and availability. Despite its severity, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), it is not listed in the KEV catalog, and there is no evidence of active exploitation or significant community discussion or media coverage.
