CVE-2003-0694

73
FAUCET Score

CVE-2003-0694 describes a critical buffer overflow vulnerability in the prescan function of Sendmail 8.12.9, allowing remote attackers to execute arbitrary code. This flaw impacts a wide range of products including Apple, Compaq, FreeBSD, Gentoo, HP, IBM, NetBSD, SGI, Sun, and TurboLinux. With a CVSS score of 10.0, it represents a severe risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. While not listed in CISA KEV, a Metasploit module exists for exploitation, and its high EPSS score indicates a significant likelihood of exploitation, despite minimal community discussion or media coverage.
