At a glance

CVE-2020-24148 is a critical-severity Server-Side Request Forgery (SSRF) vulnerability in the Import XML and RSS Feeds WordPress plugin, affecting versions < 2.0.3. It carries a CVSS score of 9.1 (reachable over the network; low attack complexity; high confidentiality, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.0.3; sites on affected versions should update now. Disclosed April 2021, reported by Suzhou Aurora Infinity Information Technology Co.

Vulnerability Overview

The Import XML and RSS Feeds plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including, 2.0.2 via the data parameter in a moove_read_xml action.

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 confidentiality, availability.

CWE-918: Server-Side Request Forgery (SSRF)

Reaching this weakness in Import XML and RSS Feeds < 2.0.3 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 Import XML and RSS Feeds the fix is 2.0.3: builds < 2.0.3 are affected, anything from 2.0.3 onward is not.

Remediation

Update to version 2.0.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Import XML and RSS Feeds: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Import XML and RSS Feeds 2.0.3 closes this, and updating the plugin is the step that ends it.
