80
FAUCET Score

CVE-2018-0127 is a critical information disclosure vulnerability affecting Cisco RV132W and RV134W VPN Routers. It allows an unauthenticated, remote attacker to view confidential configuration parameters, including the administrator password, due to a lack of authentication on specific web interface pages. With a CVSS score of 9.8 (Critical), this vulnerability is easily exploitable over the network with low attack complexity, leading to high confidentiality, integrity, and availability impacts. While not listed on CISA's KEV catalog, a Nuclei template exists for detection, and its EPSS score of 0.91541 indicates a high probability of exploitation. Despite this, there is no public exploit code in Metasploit or ExploitDB, and it has received minimal community discussion or media coverage.
