CVE-2024-12458: 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-2024-12458 is a stored cross-site scripting vulnerability in the Smart PopUp Blaster WordPress plugin (versions up to 1.4.3). It occurs due to improper neutralization of input in the 'spb-button' shortcode, where user-supplied attributes are not adequately sanitized or escaped before output. This flaw enables authenticated attackers with contributor-level privileges or higher to inject arbitrary JavaScript code that executes in the context of users visiting the compromised pages. The vulnerability is network exploitable with low attack complexity and does not require user interaction beyond visiting the injected page. The CVSS 3.1 base score is 6.4, reflecting limited confidentiality and integrity impact but no availability impact.
Potential Impact
An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable shortcode. These scripts execute in the browsers of users who view the infected pages, potentially leading to session hijacking, defacement, or other client-side attacks. The impact affects confidentiality and integrity but does not affect availability. There are no known active exploits reported at this time.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should monitor the vendor's advisory channels for updates. Until a fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the Smart PopUp Blaster plugin if feasible. Avoid using the 'spb-button' shortcode with untrusted input. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
