At a glance
CVE-2023-28413 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Snow Monkey Forms WordPress plugin, affecting versions <= 5.1.1. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 5.1.2; sites on affected versions should update now. Disclosed May 2023, reported by Monkey Wrench Inc..
Vulnerability Overview
The Snow Monkey Forms plugin for WordPress is vulnerable to Directory Traversal in versions up to, and including, 5.1.1 via the 'view' REST endpoint. This allows unauthenticated attackers to upload files with randomized names and non-executable extensions to arbitrary folders.
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.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Snow Monkey Forms <= 5.1.1 carries this weakness at view, and reaching it takes a caller who can reach the endpoint. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.
Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Snow Monkey Forms the fix is 5.1.2: builds <= 5.1.1 are affected, anything from 5.1.2 onward is not.
Remediation
Update to version 5.1.2, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Snow Monkey Forms: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Snow Monkey Forms 5.1.2 closes this, and updating the plugin is the step that ends it.
