DirectoryPress <= 3.6.16 - Authenticated (Author+) Stored Cross-Site Scripting

The DirectoryPress – Business Directory And Classified Ad Listing plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 3.6.16 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file. When DirectoryPress Frontend is installed, this can be exploited by unauthenticated users.

An attacker needs Author access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: DirectoryPress 3.6.17 closes this, and updating the plugin is the step that ends it.
