CVE-2009-0349 describes a stack-based buffer overflow vulnerability in FTPShell Server version 4.3. This flaw allows user-assisted remote attackers to trigger a denial of service (persistent daemon crash) and potentially execute arbitrary code by providing a specially crafted, long string within a licensing key (.key) file. With a CVSS score of 9.3, this vulnerability is critical, requiring medium attack complexity but no authentication, and can lead to complete compromise of confidentiality, integrity, and availability. While not listed in CISA's KEV catalog, a Proof-of-Concept exploit is publicly available on ExploitDB, though there is no evidence of active exploitation or significant community discussion.
