How the CVE Works
CVE-2025-5051 is a critical buffer overflow vulnerability in FreeFloat FTP Server 1.0, specifically within the BINARY command handler. The flaw occurs due to insufficient bounds checking when processing user-supplied input, allowing an attacker to overwrite adjacent memory regions remotely. By sending a crafted payload exceeding the allocated buffer size, an attacker can execute arbitrary code with the privileges of the FTP server. The vulnerability is exploitable without authentication, making it highly dangerous. Publicly disclosed exploits increase the risk of widespread attacks.
