CVE-2017-11420 is a critical stack-based buffer overflow vulnerability in ASUS_Discovery.c within the networkmap component of Asuswrt-Merlin firmware and various ASUS router firmware versions. This flaw allows remote attackers to execute arbitrary code by sending excessively long device information, which is mishandled during a strcat operation. With a CVSS score of 9.8 (Critical), it presents a severe risk due to its network-based attack vector, low complexity, and potential for complete compromise of confidentiality, integrity, and availability. While there is no evidence of active exploitation or public exploit code in Metasploit, Nuclei, or ExploitDB, the vulnerability has garnered significant community discussion, indicating awareness among security researchers.
