Vulnerability Overview
The Post Grid plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 2.0.12. This is due to the plugin failing to properly verify user input. This makes it possible for unauthenticated attackers to delete files on the vulnerable service.
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 integrity, availability.
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 2.0.13, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Post Grid: 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: Post Grid 2.0.13 closes this, and updating the plugin is the step that ends it.
