OVERVIEW

        A vulnerability has been discovered in Tenable Nessus 5.x prior to 
        version 2.3.3 Build #83 - #84 of the Web GUI. [1]


IMPACT

        The vendor has provided the following details regarding the 
        vulnerability:
        
        CVE-2014-7280: "The Nessus scanner's web-based user interface (Web 
        UI) was vulnerable to a stored cross-site scripting (XSS) attack. 
        The issue was due to a security control being briefly removed due to
        a regression error. During this 48 hour window, one new build of the
        Web UI was released leading to the ability to inject arbitrary 
        script code. This could be done by setting up a malicious web server
        that returned a crafted host header containing JavaScript. When 
        Nessus scanned the web server, the input would be passed as-is and 
        render when viewing a report." [1]


MITIGATION

        Tenable advises users that version 2.3.4 Build #85 has been 
        released, and will be automatically made available through the 
        plugin feed daily update. [1]
