Short explanation
The Opti-Behavior WordPress plugin up to version 1.9.2.1 is vulnerable to unauthenticated Stored DOM-Based Cross-Site Scripting via the 'country_name' location parameter.
This unauthenticated vulnerability allows attackers to inject arbitrary web scripts that execute when accessed by users, leveraging a freely obtainable nonce via a public AJAX action.
What should be done?
- Follow the vendor advisory for updates
- Update or remove the affected plugin
- Monitor input and output sanitization
Chain of evidence and sources
Opti-Behavior eklentisi 1.9.2.1 ve önceki sürümleri 'country_name' parametresi üzerinden Stored DOM-Based XSS barındırır.
Saldırganlar kimlik doğrulaması yapmadan herkese açık AJAX eylemiyle nonce elde ederek istek gönderebilir.
Show the technical text from the sources
The Opti-Behavior – Self-Hosted Heatmaps, Session Recordings, Funnels, A/B Testing & Smart Insights plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via 'country_name' Location Parameter in all versions up to, and including, 1.9.2.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The heatmap recording endpoint accepts unauthenticated requests protected only by a nonce that any visitor can freely obtain via the public opti_behavior_refresh_nonces AJAX action, removing any practical barrier to injecting the malicious payload.
