Description
Gekko Manager FTP Client <= 0.77 contains a stack-based buffer overflow in its FTP directory listing parser. When processing a server response to a LIST command, the client fails to properly validate the length of filenames. A crafted response containing an overly long filename can overwrite the Structured Exception Handler (SEH), potentially allowing remote code execution.

An exploit or proof of concept is public: anyone can try it against an unpatched system. The public collections list a Metasploit module for it. 3 references of the record are tagged as an exploit. CISA's SSVC rates its exploitation: a proof of concept is public.
