Description

h07 has discovered a vulnerability in Easy File Sharing FTP Server, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the processing of the "PASS" command. This can be exploited to cause a stack-based buffer overflow by supplying an overly long argument (more than 2571 bytes).
