At a glance

CVE-2023-41802 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Social Share, Social Login and Social Comments Plugin WordPress plugin, affecting versions <= 7.13.54. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 7.13.55; sites on affected versions should update now. Disclosed September 2023, reported by Rafshanzani Suhada.

Vulnerability Overview

The Super Socializer plugin for WordPress is vulnerable to Cross-Site Request Forgery due to missing nonce checks on several functions such as heateor_ss_twitcount_notification_read, heateor_ss_gdpr_notification_read, heateor_ss_fb_redirection_notification_read, heateor_ss_twitter_callback_notification_read, heateor_ss_linkedin_redirect_url_notification_read, heateor_ss_fb_count_notification_read, heateor_ss_twitter_new_callback_notification_read, and more in versions up to, and including, 7.13.54. This makes it possible for unauthenticated attackers to mark messages as read, 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.

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

Reaching this weakness in Social Share, Social Login and Social Comments Plugin <= 7.13.54 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 Social Share, Social Login and Social Comments Plugin the fix is 7.13.55: builds <= 7.13.54 are affected, anything from 7.13.55 onward is not.

Remediation

Update to version 7.13.55, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Social Share, Social Login and Social Comments Plugin: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Social Share, Social Login and Social Comments Plugin 7.13.55 closes this, and updating the plugin is the step that ends it.
