CVE-2024-6340: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in leap13 Premium Addons for Elementor – Powerful Elementor Templates & Widgets
The Premium Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Countdown widget in all versions up to, and including, 4.10.36 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 vulnerability was partially patched in version 4.10.36 and fully patched in version 4.10.37.
AI Analysis
Technical Summary
The Premium Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in its Countdown widget. This occurs because user-supplied attributes are not properly sanitized or escaped before being output on web pages. As a result, authenticated attackers with contributor or higher privileges can inject arbitrary JavaScript that executes when other users view the affected pages. The issue affects all versions up to 4.10.36, with a partial patch in 4.10.36 and a full patch in 4.10.37.
Potential Impact
Successful exploitation allows an attacker with contributor-level access or higher to inject persistent malicious scripts into pages, potentially leading to session hijacking, defacement, or other client-side attacks when other users access the injected content. The vulnerability does not affect availability but impacts confidentiality and integrity of user sessions and data.
Mitigation Recommendations
Users should upgrade the Premium Addons for Elementor plugin to version 4.10.37 or later, where the vulnerability is fully patched. Versions up to 4.10.36 contain only a partial fix and remain vulnerable. No other mitigations are specified by the vendor advisory. Patch status is confirmed by the plugin's version history and advisory details.
