CVE-2011-2024

34
FAUCET Score

CVE-2011-2024 describes a critical vulnerability in Cisco Network Registrar versions prior to 7.2, where a default administrative password allows unauthenticated remote attackers to gain full control over the system. This vulnerability carries a CVSS score of 10.0, indicating maximum severity due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. While the EPSS score is low, suggesting limited real-world exploitation, there is currently no public exploit code available in Metasploit or ExploitDB, and it is not listed in CISA's KEV catalog. Community discussion and media coverage for this CVE are also minimal.
