CVE-2025-2484 in Multi Video Box Plugin
Summary
by MITRE • 03/22/2025
The Multi Video Box plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'video_id' and 'group_id' parameters in all versions up to, and including, 1.5.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The Multi Video Box plugin for WordPress presents a critical reflected cross-site scripting vulnerability that affects all versions through 1.5.2, creating a significant security risk for WordPress installations. This vulnerability stems from inadequate input validation and output escaping mechanisms within the plugin's codebase, specifically targeting the 'video_id' and 'group_id' parameters. The flaw allows attackers to inject malicious scripts that execute in the context of a victim's browser when they interact with crafted links, potentially compromising user sessions and enabling further attack vectors.
The technical implementation of this vulnerability resides in the plugin's failure to properly sanitize user-supplied input parameters before processing them in web responses. When the plugin receives the 'video_id' or 'group_id' parameters through HTTP requests, it fails to adequately filter or escape these inputs before including them in the HTML output. This creates an environment where malicious payloads can be executed within the victim's browser context, as outlined in the CWE-79 category for cross-site scripting vulnerabilities. The vulnerability's impact is amplified by its accessibility to unauthenticated attackers who can exploit it through social engineering tactics.
The operational implications of this vulnerability extend beyond simple script injection, as it can enable attackers to perform a range of malicious activities including session hijacking, credential theft, and redirection to malicious sites. Attackers can craft specially formatted URLs containing malicious JavaScript payloads that, when clicked by unsuspecting users, execute in the victim's browser. This creates a persistent threat vector that can be leveraged for phishing campaigns, data exfiltration, and other advanced persistent threats. The vulnerability's exploitation requires minimal technical skill and can be automated, making it particularly dangerous for widespread deployment.
Mitigation strategies for this vulnerability should prioritize immediate plugin updates to versions that address the sanitization issues, as recommended by the WordPress security team. Organizations should implement comprehensive input validation measures that sanitize all user-supplied data before processing, particularly focusing on the identified parameter names. Network-based defenses such as web application firewalls can provide additional protection layers, though they should not replace proper code-level fixes. Security monitoring should include detection of suspicious parameter patterns and anomalous user behavior that might indicate exploitation attempts. Regular security audits of WordPress plugins and themes remain essential for identifying similar vulnerabilities that could compromise system integrity and user data confidentiality.
