Readycheck to confirm it

Titan FTP Server version 6.05 build 550 contains a heap overflow vulnerability when processing long DELE commands. Remote attackers can cause denial of service (daemon crash) or potentially execute arbitrary code by sending excessively long arguments to the DELE command.

Impact

Unauthenticated attackers can send long DELE commands to trigger heap overflow, causing denial of service by crashing the FTP daemon or potentially executing arbitrary code on the server.

Fix

Update Titan FTP Server to a version newer than 6.05 build 550 that properly validates command length and prevents heap overflow vulnerabilities in the DELE command handler.

How to confirm it

Send: tcp probe to {{Hostname}}
Positive when: contains(raw, 'Titan') and contains(version, '6.05')
