CVE-2004-0488

41
FAUCET Score

CVE-2004-0488 describes a stack-based buffer overflow in the ssl_util_uuencode_binary function of Apache mod_ssl, affecting Apache, Debian, and Red Hat distributions. This vulnerability allows remote attackers to execute arbitrary code by presenting a client certificate with an excessively long subject DN, provided mod_ssl is configured to trust the issuing Certificate Authority. With a CVSS score of 7.5, it is considered highly severe due to its network-based attack vector, low attack complexity, and potential for complete 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 surrounding this CVE.
