CVE-2024-4373: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in shaonsina Sina Extension for Elementor
The Sina Extension for Elementor (Slider, Gallery, Form, Modal, Data Table, Tab, Particle, Free Elementor Widgets & Elementor Templates) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Sina Particle Layer widget in all versions up to, and including, 3.5.3 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. CVE-2024-35703 is likely a duplicate of this issue.
AI Analysis
Technical Summary
CVE-2024-4373 describes a stored cross-site scripting vulnerability in the Sina Extension for Elementor plugin for WordPress, affecting all versions up to and including 3.5.3. The issue is due to improper neutralization of input during web page generation in the Sina Particle Layer widget, allowing authenticated users with contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute in the context of users who access the injected pages. The vulnerability has a CVSS v3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial confidentiality and integrity impact with no availability impact. CVE-2024-35703 is likely a duplicate of this issue. No patch or official fix has been disclosed yet.
Potential Impact
An attacker with contributor-level or higher privileges can exploit this vulnerability to inject persistent malicious scripts into pages generated by the plugin. This can lead to partial compromise of confidentiality and integrity for users who view the affected pages, such as theft of session tokens or manipulation of page content. There is no impact on availability. No known exploits have been reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level and higher access to trusted users only. Consider disabling or removing the Sina Particle Layer widget if feasible to reduce exposure.
