30
FAUCET Score

CVE-2018-20512 describes a critical privilege escalation vulnerability affecting EPON CPE-WiFi devices running firmware version 2.0.4-X000 from cdatatec. An unauthenticated attacker can achieve administrative privileges by manipulating specific cookie values (cooLogin, cooUser, timestamp). This vulnerability carries a CVSS score of 9.8 (CRITICAL) due to its network-based attack vector, low complexity, and high impact on confidentiality, integrity, and availability. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the severe nature of the flaw warrants immediate attention for affected systems.
