At a glance

CVE-2020-24141 is a medium-severity Server-Side Request Forgery (SSRF) vulnerability in the WP-DownloadManager WordPress plugin, affecting versions < 1.68.5. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview

Server-side request forgery in the WP-DownloadManager plugin 1.68.4 for WordPress lets an attacker send crafted requests from the back-end server of a vulnerable web application via the file_remote parameter to download-add.php. It can help identify open ports, local network hosts and execute command on services

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-918: Server-Side Request Forgery (SSRF)

Reaching this weakness in WP-DownloadManager < 1.68.5 takes a caller who can reach the endpoint. Server-side request forgery means the application fetches a URL supplied by the caller, turning the server into a proxy for requests the attacker could not make directly.

The request originates from inside the hosting network, which is how these flaws reach cloud metadata endpoints, internal admin panels and services that trust local traffic. For WP-DownloadManager the fix is 1.68.5: builds < 1.68.5 are affected, anything from 1.68.5 onward is not.

Remediation

Update to version 1.68.5, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP-DownloadManager: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP-DownloadManager 1.68.5 closes this, and updating the plugin is the step that ends it.
