AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a stack-based buffer overflow in the LeapFTP client parser for versions earlier than 3.1.x. When the FTP client receives a directory listing with a filename longer than 528 bytes, it does not properly check the length of the input. This causes the application to overwrite the Structured Exception Handler (SEH) chain, which can be exploited by an attacker controlling a malicious FTP server to execute arbitrary code on the victim's machine when the file is listed or downloaded.
How can this vulnerability impact me? :
This vulnerability can allow an attacker operating a malicious FTP server to execute arbitrary code on your machine without your permission. This could lead to full compromise of your system, including unauthorized access, data theft, or further malware installation, simply by listing or downloading a specially crafted file from the FTP server.
