FTP Navigator 8.03 contains a stack overflow vulnerability that allows attackers to execute arbitrary code by overwriting Structured Exception Handler (SEH) registers. Attackers can craft a malicious payload that triggers a buffer overflow when pasted into the Custom Command textbox, enabling remote code execution and launching the calculator as proof of concept.
