Technical details

A classic buffer overflow (CWE-120) exists in SpotFTP FTP Password Recovery version 3.0.0.0 within the registration name input field. The vulnerability is triggered when a user pastes a specially crafted payload (approximately 1,000 characters) into the 'Name' field of the registration dialog. This lack of input validation leads to a memory corruption that causes the application to crash (Denial of Service). Exploitation requires local access and user interaction to paste the malicious string into the application interface. A public Proof of Concept (PoC) is available.
