CVE-2011-1520

22
FAUCET Score

CVE-2011-1520 describes a critical vulnerability in the default configuration of IBM Lotus Domino's server console, where no password is required. This allows physically proximate attackers to execute administrative commands like Load, Tell, or Set Configuration, leading to complete compromise of confidentiality, integrity, and availability. With a CVSS score of 7.2 (AV:L/AC:L/Au:N/C:C/I:C/A:C), this vulnerability is easily exploitable with local access and no authentication. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the potential for severe impact remains high.
