What is CVE-2010-20107?

A stack-based buffer overflow was discovered in FTP Synchronizer Professional versions up to 4.0.73.274. When a user connects the client to an FTP server and issues a LIST command—commonly during synchronization previews or profile setups—an unexpectedly long filename in the server's response can trigger this overflow. This vulnerability compromises the Structured Exception Handler (SEH), which could allow an attacker to execute arbitrary code remotely, putting systems at significant risk.

Affected Version(s)

FTP Synchronizer Professional * <= 4.0.73.274

Exploit Proof of Concept (PoC)
