How the CVE Works
CVE-2025-4792 is a critical buffer overflow vulnerability in FreeFloat FTP Server 1.0, specifically in the MDELETE command handler. The flaw occurs due to improper bounds checking when processing overly long input, allowing remote attackers to overwrite adjacent memory. This can lead to arbitrary code execution or server crashes. The attack is network-exploitable without authentication, making it highly dangerous. Publicly disclosed exploit code increases the risk of widespread abuse.
