Trend Micro Worry-Free Business Security Path Traversal Authentication Bypass (000245572)

critical Nessus Plugin ID 139667

Language:

Synopsis

The remote host is running an application that is affected by a path traversal vulnerability.

Description

The Trend Micro Worry-Free Business Security (WFBS) is affected by a path traversal vulnerability in cgiRecvFile.exe due to improper validation of a user-supplied path prior to using it in file operations when handling the TempFileName parameter in an HTTP request. An unauthenticated, remote attacker can exploit this, via a specially crafted message, to manipulate a key file to bypass authentication.

Note that the application is reportedly affected by other vulnerabilities; however, this plugin has not tested for those issues.

Solution

Upgrade WFBS to version 10 SP1 build 2185 / 9.5 build 1525 or later.
