CVE-2006-5815 is a critical stack-based buffer overflow vulnerability affecting ProFTPD versions 1.3.0 and earlier, specifically within the sreplace function. This flaw allows remote, likely authenticated, attackers to trigger a denial of service and execute arbitrary code on affected systems. With a CVSS score of 10.0, it presents a severe risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability.
