**Name of the Vulnerable Software and Affected Versions** ProFTPD version 1.3.7a **Description** A denial of service issue allows attackers to overwhelm the server by creating multiple simultaneous FTP connections. By repeatedly establishing connections using threading, attackers can exhaust server connection limits and block legitimate user access. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** VSFTPD version 3.0.3 **Description** The issue allows attackers to cause a denial of service due to a limited number of connections allowed. **Recommendations** For VSFTPD version 3.0.3, at the moment, there is no information about a newer version that contains a fix for this issue.

**Name of the Vulnerable Software and Affected Versions** Pure-FTPd version 1.0.48 **Description** The issue allows remote attackers to prevent legitimate server use by making enough connections to exceed the connection limit. **Recommendations** For Pure-FTPd version 1.0.48, consider increasing the connection limit or implementing rate limiting to prevent abuse. As a temporary workaround, restrict access to the server to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
