Title: Cerberus FTP Server Buffer Overflow DoS Vulnerability
Severity: HIGH
Description:
Cerberus FTP Server is a free, multi-threaded file transfer utility for Microsoft Windows systems.
There is a buffer overflow in Cerberus FTP Server. The problem occurs when a user is attempting to authenticate. To exploit this vulnerability both of the login fields(username, password) must be filled with an excessive amount of data, in this case 300 or more characters.
The affected service will crash, due to its inability to handle so much input into the specified fields.
It has also been reported that entering an excessive amount of characters in just the password field will acheive the same result.
The FTP Server software will need to be restarted to regain normal functionality.
Due to the fact that the problem stems from a buffer overflow, there is a possibility that arbitrary code may be executed on the vulnerable host.
This vulnerability does not require any user authentication to exploit. It may be possible for remote users to cause a denial of service or execute arbitrary code on target hosts.
