Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The remote host has a version of Advantech WebAccess prior to version 7.2-2014.06.06. It is, therefore, affected by multiple vulnerabilities :

- Multiple stack overflows can be triggered with overly long strings to the 'ProjectName', 'SetParameter', 'NodeName', 'CCDParameter', 'SetColor', 'AlarmImage', 'GetParameter', 'GetColor', 'ServerResponse', 'SetBaud', and 'IPAddress' parameters of the webvact.ocx, dvs.ocx, and webdact.ocx ActiveX files. (CVE-2014-2364)

- An unspecified flaw exists in WebAccess that allows an attacker to create or delete arbitrary files. (CVE-2014-2365)

- The pAdminPg.asp component includes the password of the specified account in the underlying HTML. (CVE-2014-2366)

- The ChkCookie subroutine in the broadweb\include\gChkCook.asp ActiveX control can be abused to bypass authentication. (CVE-2014-2367)

- The 'BrowseFolder' method of the bwocxrun ActiveX control allows navigation from the Internet to a local file. (CVE-2014-2368)

Solution

Upgrade to Advantech WebAccess version 7.2-2014.06.06 or higher.
