CVE-2024-5937: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in mardojai Simple Alert Boxes
The Simple Alert Boxes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Alert shortcode in all versions up to, and including, 1.4.0 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.
AI Analysis
Technical Summary
CVE-2024-5937 is a stored cross-site scripting vulnerability in the Simple Alert Boxes WordPress plugin (versions up to 1.4.0). The vulnerability is due to improper neutralization of input during web page generation, specifically insufficient input sanitization and output escaping of user-supplied attributes in the Alert shortcode. This allows authenticated users with contributor-level access or higher to inject arbitrary scripts that execute in the context of other users viewing the injected pages. The CVSS 3.1 score is 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, scope change, and limited confidentiality and integrity impact without availability impact.
Potential Impact
An attacker with contributor-level or higher privileges can inject malicious JavaScript into pages via the Alert shortcode. This script executes in the browsers of users who view the compromised pages, potentially leading to session hijacking, defacement, or other client-side impacts. The vulnerability affects confidentiality and integrity but does not impact availability. There are no known exploits in the wild currently.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only. Monitor plugin updates from the vendor for an official fix. Avoid using the Alert shortcode with untrusted input.
