    Title
    Quttera ThreatSign <= 4.1.0.48 - Unauthenticated Stored Cross-Site Scripting via User-Agent Header
    Summary
    The Quttera ThreatSign – Web Malware Scanner for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'HTTP_USER_AGENT' parameter in all versions up to, and including, 4.1.0.48 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 an administrator accesses an injected page.
