CVE-2004-0437

CVE-2004-0437 describes a denial-of-service vulnerability in Titan FTP Server versions 3.01 build 163 and potentially earlier versions. An authenticated remote attacker can crash the server by disconnecting during a "LIST -L" command, leading to an invalid socket access. The vulnerability has a CVSS score of 5.0, indicating a medium severity. It is easily exploitable over the network with low attack complexity and no authentication required (though the description mentions "authenticated users," the CVSS vector suggests otherwise for the base score), resulting in a partial availability impact. While not actively exploited in the wild and not listed in CISA's KEV catalog, exploit code is publicly available via ExploitDB and Nuclei templates. There is minimal community discussion or media coverage surrounding this older vulnerability.
