CVE-2013-3623

80
FAUCET Score

CVE-2013-3623 describes multiple stack-based buffer overflows in the close_window.cgi script of the web interface for Supermicro X9 generation motherboards running Intelligent Platform Management Interface (IPMI) firmware prior to version 3.15. This vulnerability allows remote, unauthenticated attackers to execute arbitrary code by manipulating the 'sess_sid' or 'ACT' parameters. With a CVSS score of 10.0, it represents a critical risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. While not on the CISA KEV list, public exploit code exists, including a Metasploit module, though there is minimal community discussion or media coverage surrounding this decade-old vulnerability.
