What the vulnerability does

01Description

A buffer overflow vulnerability exists in the WinaXe FTP Client version 7.7 within the FTP banner parsing functionality, WCMDPA10.dll. When the client connects to a remote FTP server and receives an overly long '220 Server Ready' response, the vulnerable component responsible for parsing the banner overflows a stack buffer, leading to arbitrary code execution under the context of the user.
