CVE-2024-8672: Detailed Vulnerability Analysis and Overview

CVE-2024-8672 Vulnerability Summary

The Widget Options – The #1 WordPress Widget & Block Control Plugin plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.0.7 via the display logic functionality that extends several page builders. This is due to the plugin allowing users to supply input that will be passed through eval() without any filtering or capability checks. This makes it possible for authenticated attackers, with contributor-level access and above, to execute code on the server. Special note: We suggested the vendor implement an allowlist of functions and limit the ability to execute commands to just administrators, however, they did not take our advice. We are considering this patched, however, we believe it could still be further hardened and there may be residual risk with how the issue is currently patched.

• Code Injection: An adversary exploits a weakness in input validation on the target to inject new code into that which is currently executing. This differs from code inclusion in that code inclusion involves the addition or replacement of a reference to a code file, which is subsequently loaded by the target and used as part of the code of some application.
• Leverage Executable Code in Non-Executable Files: An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
• Manipulating User-Controlled Variables: This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An adversary can override variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the adversary can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.
