CVE-2000-1047

26
FAUCET Score

CVE-2000-1047 describes a buffer overflow vulnerability in the SMTP service of Lotus Domino 5.0.4 and earlier versions, impacting both the Enterprise and Mail Server products. This flaw allows remote, unauthenticated attackers to trigger a denial of service and potentially execute arbitrary code by sending a specially crafted, long ENVID keyword within the "MAIL FROM" command. With a CVSS score of 10.0, this vulnerability is considered critical due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its high severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not currently a target for attackers.
