CVE-2008-0590

CVE-2008-0590 describes a critical buffer overflow vulnerability in Ipswitch WS_FTP Server with SSH version 6.1.0.0. This flaw allows remote authenticated users to trigger a denial of service and potentially execute arbitrary code by sending an excessively long "opendir" command. With a CVSS score of 9.0, this vulnerability is highly severe, as it can be exploited over the network with low attack complexity by an authenticated user, leading to complete compromise of confidentiality, integrity, and availability. While not listed on the KEV catalog, a proof-of-concept exploit is publicly available on ExploitDB, though there is no evidence of active exploitation or significant community discussion.
