At a glance

CVE-2023-5882 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the WP All Export Pro WordPress plugin, affecting versions < 1.8.6. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.8.6; sites on affected versions should update now. Disclosed November 2023, reported by Donato Di Pasquale.

Vulnerability Overview

The Export any WordPress data to XML/CSV plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to 1.4.1, and in versions up to 1.8.6 in the PRO version. This is due to missing nonce validation on a function. This makes it possible for unauthenticated attackers to perform unauthorized actions and achieve remote code execution via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in WP All Export Pro < 1.8.6 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For WP All Export Pro the fix is 1.8.6: builds < 1.8.6 are affected, anything from 1.8.6 onward is not.

Remediation

Update to version 1.8.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP All Export Pro: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP All Export Pro 1.8.6 closes this, and updating the plugin is the step that ends it.
