At a glance
CVE-2024-13375 is a critical-severity Unverified Password Change vulnerability in the Adifier - Classified Ads WordPress Theme WordPress theme, affecting versions <= 3.1.7. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.1.8; sites on affected versions should update now. Disclosed January 2025, reported by Tonn.
Vulnerability Overview
The Adifier System plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 3.1.7. This is due to the plugin not properly validating a user's identity prior to updating their details like password through the adifier_recover() function. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, 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-620: Unverified Password Change
Adifier - Classified Ads WordPress Theme <= 3.1.7 carries this weakness at adifier_recover(), and reaching it takes no account at all. Unverified password change means the password-update path does not require proof that the requester is the account owner.
An attacker who can reach the endpoint takes over the account outright, and the legitimate owner is locked out of it. For Adifier - Classified Ads WordPress Theme the fix is 3.1.8: builds <= 3.1.7 are affected, anything from 3.1.8 onward is not.
Remediation
Update to version 3.1.8, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Adifier - Classified Ads WordPress Theme 3.1.8 closes this, and updating the theme is the step that ends it.
