Vulnerability Information

Severity: High
Vulnerability Published: N/A
Patch Published: N/A
CVE [?]: CVE-2008-4385
CPE [?]: N/A

Synopsis

The remote Windows host has an ActiveX control that could allow arbitrary code execution.

Description

Instant Expert Analysis from Husdawg System Requirements Lab is installed on the remote host. Instant Expert Analysis software allows websites to perform one-click software/hardware analysis of remote systems.

An ActiveX component used by Instant Expert Analysis can be exploited to download and execute malicious code from an unauthorized website. Although, the software uses a signed Java applet to download and execute files, it may be possible to execute code without any user interaction if the applet is previously signed on an authorized website.

Reportedly either file 'sysreqlab.dll', 'sysreqlabsli.dll', or 'sysreqlab2.dll' is affected by this issue.

Solution

Upgrade to Husdawg System Requirements Lab 3.
