CVE-2018-1000505
At a glance
CVE-2018-1000505 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Tooltipy (tooltips for WP) WordPress plugin, affecting versions < 5.1. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication. The issue is fixed in version 5.1; sites on affected versions should update now. Disclosed June 2018, reported by dwxsupport.
Vulnerability Overview
The Tooltipy plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.0. This is due to missing or incorrect nonce validation on the post_type function. This makes it possible for unauthenticated attackers to caused a Deniel of Service of the database 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 integrity.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Tooltipy (tooltips for WP) < 5.1 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 Tooltipy (tooltips for WP) the fix is 5.1: builds < 5.1 are affected, anything from 5.1 onward is not.
Remediation
Update to version 5.1, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Tooltipy (tooltips for WP): WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Tooltipy (tooltips for WP) 5.1 closes this, and updating the plugin is the step that ends it.
