CVE-2001-0499

85
FAUCET Score

CVE-2001-0499 describes a critical buffer overflow vulnerability in the Transparent Network Substrate (TNS) Listener of Oracle 8i (version 8.1.7 and earlier). This flaw allows unauthenticated remote attackers to execute arbitrary code and gain full control over affected systems by sending an overly long argument to several TNS Listener commands. With a CVSS score of 10.0, this vulnerability presents a high risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. While not on the KEV catalog, public exploit modules exist in Metasploit and ExploitDB, indicating readily available tools for exploitation, though there is no recent community discussion or media coverage.
