At a glance

CVE-2022-1977 is a medium-severity Server-Side Request Forgery (SSRF) vulnerability in the WP Ultimate CSV Importer WordPress plugin, affecting versions <= 6.5.2.

Disclosed June 2022, reported by Luan Pedersini.

Vulnerability Overview

The Import Export All WordPress Images, Users & Post Types WordPress plugin before 6.5.3 does not fully validate the file to be imported via an URL before making an HTTP request to it, which could allow high privilege users such as admin to perform Blind SSRF attacks

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.

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

Reaching this weakness in WP Ultimate CSV Importer <= 6.5.2 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 Ultimate CSV Importer the fix is 6.5.3: builds <= 6.5.2 are affected, anything from 6.5.3 onward is not.

Remediation

Update to version 6.5.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP Ultimate CSV Importer: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Ultimate CSV Importer 6.5.3 closes this, and updating the plugin is the step that ends it.
