36
FAUCET Score

CVE-2016-1558 describes a critical buffer overflow vulnerability in multiple D-Link DAP series access points, including models like the DAP-2310, DAP-2330, and DAP-2695, affecting various firmware versions. This flaw allows remote, unauthenticated attackers to achieve a severe impact (confidentiality, integrity, and availability) by sending a specially crafted 'dlink_uid' cookie. With a CVSS v3 score of 9.8, it is considered critical due to its network-based attack vector and low attack complexity. While there is no evidence of active exploitation (not in KEV) and no public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered significant community discussion, indicating awareness among security researchers.
