CVE-2024-12066
At a glance
CVE-2024-12066 is a high-severity External Control of File Name or Path vulnerability in the SMSA Shipping (official) WordPress plugin, affecting versions <= 2.3. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 2.4; sites on affected versions should update now. Disclosed December 2024, reported by Brian Sans-Souci (liardom).
Vulnerability Overview
The SMSA Shipping(official) plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the smsa_delete_label() function in all versions up to, and including, 2.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). CVE-2024-49249 is likely a duplicate of this issue.
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 interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-73: External Control of File Name or Path
The product allows user input to control or influence paths or file names that are used in filesystem operations.
Remediation
Update to version 2.4, or a newer patched version
How does WordSec protect against this?
An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: 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: SMSA Shipping (official) 2.4 closes this, and updating the plugin is the step that ends it.
