CVE-2005-1992

CVE-2005-1992 describes a critical vulnerability in the XMLRPC server component of the Ruby library (libruby) version 1.8, specifically within utils.rb, which affects products like yukihiro_matsumoto ruby. The flaw stems from an invalid default value that bypasses intended security protections, enabling remote attackers to execute arbitrary commands. With a CVSS score of 7.5, this vulnerability is easily exploitable over the network with low attack complexity, potentially leading to partial compromise of confidentiality, integrity, and availability. Despite its age and high FAUCET Risk Score, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
