CVE-2024-11339: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in devnethr Smart PopUp Blaster
The Smart PopUp Blaster plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'spb-button' shortcode in all versions up to, and including, 1.4.3 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.
AI Analysis
Technical Summary
CVE-2024-11339 is a stored cross-site scripting vulnerability in the Smart PopUp Blaster WordPress plugin (versions up to 1.4.3). The issue is due to improper neutralization of input during web page generation, specifically in the 'spb-button' shortcode, allowing authenticated users with contributor or higher privileges to inject arbitrary scripts. These scripts execute in the context of users viewing the injected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 base score of 6.4 (medium severity), with network attack vector, low attack complexity, privileges required, no user interaction, and impacts confidentiality and integrity with no availability impact. No known exploits in the wild or vendor patches have been reported as of the published date.
Potential Impact
An attacker with contributor-level or higher access can exploit this vulnerability to inject persistent malicious scripts into pages via the 'spb-button' shortcode. When other users access these pages, the injected scripts execute in their browsers, potentially compromising user sessions or data confidentiality and integrity. The vulnerability does not affect availability. There are no known active exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the Smart PopUp Blaster plugin if possible. Monitor for vendor updates regarding patches or official mitigations.
