Vulnerability Data

The Ultimate Blogroll plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.5.2. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to…

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

CSRF in public-facing WordPress plugin directly enables exploitation of the web application for unauthorized actions and script injection.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of security tokens such as nonces on all state-changing requests, blocking the forged CSRF actions described in the CVE.

prevent

Enforces that every privileged action (settings update, script injection) must be accompanied by a valid authenticated request, preventing the missing-nonce bypass.

prevent

Protects session authenticity so that cookie-based credentials cannot be silently reused by an attacker-supplied forged request.

mitigates

By denying access to phishing or malicious sites, the control lowers the likelihood that a user will be tricked into submitting a forged request that performs an unintended action on another site.
