CVE-2024-11379: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in edward_plainview Broadcast
The Broadcast plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'do_check' parameter in all versions up to, and including, 51.01 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. This only affects multi-site installations.
AI Analysis
Technical Summary
The Broadcast plugin for WordPress suffers from a reflected XSS vulnerability due to improper neutralization of input in the 'do_check' parameter. This vulnerability affects multi-site WordPress installations using versions up to 51.01. An attacker can craft a malicious URL containing script code in the 'do_check' parameter, which, when clicked by a user, executes in the context of the victim's browser. This can lead to limited confidentiality and integrity impacts, such as theft of user session data or manipulation of page content. The vulnerability requires user interaction and no privileges are needed to exploit it.
Potential Impact
Successful exploitation allows an unauthenticated attacker to execute arbitrary scripts in the context of a victim's browser session on multi-site WordPress installations using the vulnerable Broadcast plugin. This can lead to limited confidentiality and integrity impacts, such as theft of cookies or session tokens and manipulation of displayed content. There is no impact on availability. The vulnerability is rated medium severity with a CVSS score of 6.1.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, administrators of multi-site WordPress installations using the Broadcast plugin should consider disabling the plugin or restricting access to affected parameters. Avoid clicking on suspicious links that may exploit this vulnerability.
