Description

The CM Business Directory – Optimise and showcase local business plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Business Address Meta Fields in all versions up to, and including, 1.5.7 due to insufficient input sanitization and output escaping. 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. Because the malicious payload is stored in post meta rather than post_content, WordPress's unfiltered_html capability restriction does not apply, meaning contributors who lack that capability can still inject executable HTML via the address meta fields such as cmbd_address, cmbd_cityTown, cmbd_stateCounty, cmbd_postalcode, cmbd_region, and cmbd_country.

• CWE-79Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
