CVE-2007-4440 describes a stack-based buffer overflow in the MercuryS SMTP server within the Mercury Mail Transport System, potentially affecting version 4.51 and earlier. This vulnerability allows remote, unauthenticated attackers to execute arbitrary code by sending a crafted, long AUTH CRAM-MD5 string. 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. While not listed in CISA KEV, exploit code is publicly available, including a Metasploit module and multiple Proof-of-Concept exploits on ExploitDB, indicating a high likelihood of exploitation. Despite this, there is minimal community discussion or media coverage surrounding this CVE.
