Category:FTP
Title:wu-ftpd ABOR privilege escalation
Summary:The remote Wu-FTPd server seems to be vulnerable to a remote privilege; escalation.
Description:Summary:
The remote Wu-FTPd server seems to be vulnerable to a remote privilege
escalation.

Vulnerability Insight:
This version contains a flaw that may allow a malicious user to gain
access to unauthorized privileges.

Specifically, there is a flaw in the way that the server handles an ABOR command after a data connection
has been closed. The flaw is within the dologout() function and proper exploitation will give the
remote attacker the ability to execute arbitrary code as the 'root' user.

Vulnerability Impact:
This flaw may lead to a loss of confidentiality and/or integrity.

Solution:
Upgrade to Wu-FTPd 2.4.2 or newer.

CVSS Score:
5.0
