WinSCP < 4.0.4 URL Protocol Handler Arbitrary File Transfer

Medium

Synopsis

The remote Windows host has a program that allows arbitrary file access.

Description

According to its version, the installation of WinSCP on the remote host fails to completely sanitize input to the SCP and SFTP protocol handlers. If an attacker can trick a user on the affected host into clicking on a malicious link, he may be able to initiate a file transfer to or from the affected host.

Solution

Upgrade to version 4.0.4 or higher.
