Name of the Vulnerable Software and Affected Versions NextScripts: Social Networks Auto-Poster plugin for WordPress versions up to, and including, 4.4.3

Description The issue allows unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is possible due to insufficient input sanitization and output escaping via the HTTP USER AGENT header. The injection requires the victim to select view "All Cron Events" in order for it to fire.

Recommendations For versions up to, and including, 4.4.3, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the "All Cron Events" view to minimize the risk of exploitation.
