New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 5.9


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


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.


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