Maspik – Spam blacklist < 0.9.3 - Unauthenticated Stored Cross-Site Scripting via efas_add_to_log

Description

The Maspik – Spam Blacklist plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the efas_add_to_log function in all versions up to, and including, 0.9.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
