CWE-623: Unsafe ActiveX Control Marked Safe For Scripting
Learn about CWE-623 (Unsafe ActiveX Control Marked Safe For Scripting), its security impact, exploitation methods, and prevention guidelines.
What is Unsafe ActiveX Control Marked Safe For Scripting?
• Overview: An ActiveX control that is supposed to have limited use is incorrectly labeled as safe-for-scripting, which can be exploited by attackers to perform unauthorized actions through a web page.
• Exploitation Methods:
- Attackers can craft malicious web pages to invoke the unsafe ActiveX control.
- Common techniques include embedding the ActiveX control in a webpage and using scripting to manipulate it for unintended operations.
• Security Impact:
- Direct consequences include unauthorized access or execution of code on a user's machine.
- Potential cascading effects involve further exploitation of the system, leading to data theft, system compromise, or spreading malware.
- Business impact could be damage to reputation, compliance violations, and financial losses due to data breaches or service disruption.
• Prevention Guidelines:
- Specific code-level fixes include ensuring that ActiveX controls are correctly marked and not labeled as safe-for-scripting if they are not intended for that use.
- Security best practices involve conducting thorough security reviews of ActiveX controls and implementing least privilege principles.
- Recommended tools and frameworks include using Microsoft's Static Analysis Tool for checking ActiveX controls and employing secure coding practices to minimize risk.
