CVE-2024-12452 in Ziggeo Plugin
Summary
by MITRE • 02/21/2025
The Ziggeo plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ziggeo_event' shortcode in all versions up to, and including, 3.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Ziggeo plugin for WordPress represents a media recording and streaming solution that integrates video capabilities into wordpress environments through various shortcode implementations. This particular vulnerability affects all versions up to and including 3.1, making it a widespread concern for wordpress installations that utilize this plugin for video content management. The vulnerability manifests through the plugin's 'ziggeo_event' shortcode which processes user-supplied attributes without adequate sanitization measures, creating a persistent cross-site scripting attack vector that can be exploited by authenticated users with contributor-level permissions or higher.
The technical flaw stems from insufficient input sanitization and output escaping mechanisms within the plugin's shortcode processing code. When administrators or contributors embed the ziggeo_event shortcode with user-controllable attributes, the plugin fails to properly validate or escape these inputs before rendering them in the output HTML. This vulnerability operates under the common weakness identified as CWE-79, which describes improper neutralization of input during web page generation, specifically manifesting as stored cross-site scripting. The flaw allows attackers to inject malicious scripts that persist in the database and execute whenever any user accesses pages containing the vulnerable shortcode, making it particularly dangerous for environments where multiple users interact with content management.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers with contributor privileges to compromise the integrity of wordpress installations and potentially escalate their access privileges. Since the injection occurs through the shortcode attribute processing, any user with contributor-level access can manipulate the system by inserting malicious JavaScript code into video-related content that will execute in the context of other users' browsers. This creates a persistent threat vector where compromised users may unknowingly execute malicious code when viewing pages containing the injected scripts, potentially leading to session hijacking, data theft, or further system compromise. The vulnerability affects not only individual user sessions but also the overall security posture of wordpress installations that rely on this plugin for media content management.
Mitigation strategies should focus on immediate version updates to the latest available plugin releases that address the sanitization and escaping vulnerabilities. Organizations should implement strict input validation measures and ensure that all user-supplied data passed to shortcode attributes undergoes proper sanitization before processing. The ATT&CK framework identifies this as a potential technique for privilege escalation through web application vulnerabilities, specifically under the category of code injection attacks. System administrators should also consider implementing content security policies that limit script execution and monitor for suspicious shortcode usage patterns. Additionally, regular security audits of wordpress plugins should include verification of input sanitization practices and output escaping mechanisms to prevent similar vulnerabilities from being introduced through third-party integrations.
