CVE-1999-1511

CVE-1999-1511 describes multiple buffer overflow vulnerabilities in Artisoft Xtramail version 1.11. Attackers can trigger these by sending overly long commands (PASS, HELO, or username) to the POP3, SMTP, or Control services, respectively. This can lead to a denial of service (crash) and potentially arbitrary code execution. With a CVSS score of 7.5 (HIGH), this vulnerability is easily exploitable over the network with low attack complexity and no authentication required, allowing for potential compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, publicly available exploit code in common databases like Metasploit or ExploitDB, nor significant community discussion or media coverage surrounding this older vulnerability.
