CVE-2022-4578 – Video Conferencing with Zoom < 4.0.10 - Contributor+ Stored XSS

https://notcve.org/view.php?id=CVE-2022-4578

The Video Conferencing with Zoom WordPress plugin before 4.0.10 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins. El complemento Video Conferencing with Zoom para WordPress anterior a 4.0.10 no valida ni escapa algunos de sus atributos de código corto antes de devolverlos a la página, lo que podría permitir a los usuarios con un rol tan bajo como colaborador realizar ataques de cross-site scripting almacenado que podrían utilizarse contra usuarios con privilegios elevados, como administradores. The Video Conferencing with Zoom plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcode in versions up to, and including, 4.0.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. • https://wpscan.com/vulnerability/fad16c68-9f14-4866-b241-40468fb71494 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
