CVE-2005-4411 describes a critical buffer overflow vulnerability in Mercury Mail Transport System 4.01b, specifically affecting the PH Server module. This flaw allows unauthenticated remote attackers to execute arbitrary code by sending a specially crafted, excessively long request to TCP port 105. With a CVSS score of 7.5, it represents a high-severity risk 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 intelligence indicates readily available public exploit code, including Metasploit modules and ExploitDB entries, though community discussion and media coverage are minimal.
