CVE-2024-13221 Scanner

Fantastic ElasticSearch WordPress Plugin is commonly used by web administrators and content managers to enhance search capabilities on WordPress sites. This plugin integrates ElasticSearch solutions to provide users with fast and efficient search results, making it ideal for websites with large volumes of content. Developed by Parisholley, it is suitable for small blogs to enterprise-level WordPress implementations. It is employed by developers and site owners who need advanced search features within their WordPress framework. With the ongoing need for precise information retrieval, this plugin remains relevant in maintaining high-quality content management systems. Regular updates and user community support enhance its utility and security.

The vulnerability in question is a Cross-Site Scripting (XSS) which allows attackers to execute malicious scripts in the context of a user's browser. This is triggered by unsanitized input parameters output, particularly in high privilege user sessions. Exploiting this vulnerability requires the user to visit a crafted link, which then executes the attacker's script. The compromise can be severe as it targets user's browser sessions, leading to session hijacking or privilege escalation. The execution could involve injecting scripts that modify overlaid content or steal sensitive information under authorized user contexts.

Technical details reveal that the vulnerable endpoint includes a specific page parameter where script tags can be injected. The parameter lacks proper input sanitization and encoding, allowing an attacker to insert scripts directly into web responses. By crafting a URL that an administrator or high privilege user accesses, attackers can trigger arbitrary JavaScript execution. This can be done by embedding the attack payload into a URL linking to a specific register within the plugin's administration panel. The attack can be executed remotely, emphasizing the medium-high impact provided the conditions are met to exploit.

Exploiting this vulnerability could have widespread effects, including unauthorized actions on behalf of high privilege users. This might entail actions such as changing plugin settings, accessing sensitive data, or even unwarranted content alterations on the targeted WordPress site. The broader impact could involve compromise of visitor data security, undermining trust in the site's safety for users. A successful exploit could also pave the way for further attacks, leveraging the compromised session to access other connected services or accounts. Corporate or social media pages managed through the compromised site might also suffer from unauthorized activity, damaging reputation.
