Vulnerability Overview
The MediCenter - Health Medical Clinic theme for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 15.1 via deserialization of untrusted input. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-502: Deserialization of Untrusted Data
Reaching this weakness in MediCenter - Health Medical Clinic WordPress Theme <= 15.1 takes no account at all. Deserialization of untrusted data means the application reconstructs objects from input a caller controls, letting the attacker choose which classes get instantiated and what their properties hold.
A workable chain turns deserialization into file writes, deletions or code execution, depending on what the loaded classes do in their magic methods. For MediCenter - Health Medical Clinic WordPress Theme the fix is 15.2: builds <= 15.1 are affected, anything from 15.2 onward is not.
Remediation
Update to version 15.2, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: MediCenter - Health Medical Clinic WordPress Theme 15.2 closes this, and updating the theme is the step that ends it.
