At a glance

This record tracks a medium-severity Relative Path Traversal vulnerability in the WPvivid WordPress plugin, affecting versions <= 0.9.75. It carries a CVSS score of 6.0 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Admin level or above. The issue is fixed in version 0.9.76; sites on affected versions should update now. Disclosed August 2022.

Vulnerability Overview

The WPvivid plugin for WordPress is vulnerable to directory traversal in versions up to, and including, 0.9.75. This allows authenticated users with administrative privileges to download arbitrary files on the server, including sensitive configuration files, though the file size must be successfully guessed in order to do so.

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.

CWE-23: Relative Path Traversal

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as .. that can resolve to a location that is outside of that directory.

Remediation

Update to version 0.9.76, or a newer patched version

How does WordSec protect against this?

An attacker needs Admin 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. None of that substitutes for the fix: WPvivid 0.9.76 closes this, and updating the plugin is the step that ends it.
