Overview

CVE-2014-0773 is a high-severity vulnerability affecting advantech advantech_webaccess. It was published on April 12, 2014 and has a CVSS 2.0 base score of 7.5 (HIGH).

This vulnerability has a CVSS 2.0 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The BWOCXRUN.BwocxrunCtrl.1 control contains a method named

“CreateProcess.” This method contains validation to ensure an attacker

cannot run arbitrary command lines. After validation, the values

supplied in the HTML are passed to the Windows CreateProcessA API.

The validation can be bypassed allowing for running arbitrary command

lines. The command line can specify running remote files (example: UNC

command line).

A function exists at offset 100019B0 of bwocxrun.ocx. Inside this

function, there are 3 calls to strstr to check the contents of the user

specified command line. If “\setup.exe,” “\bwvbprt.exe,” or

“\bwvbprtl.exe” are contained in the command line (strstr returns

nonzero value), the command line passes validation and is then passed to

CreateProcessA.

Remediation

Check the references section for vendor advisories and patches from advantech. Update advantech_webaccess to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
