CVE-2012-4694

23
FAUCET Score

CVE-2012-4694 describes a critical vulnerability in Moxa EDR-G903 series routers with firmware older than 2.11, where insufficient entropy in SSH and SSL key generation allows for easier man-in-the-middle attacks. With a CVSS score of 7.6, this vulnerability carries a high severity due to its network-based attack vector, high attack complexity, and complete compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it has not garnered widespread attention.
