Detailsinfo

A vulnerability was found in Tenable Nessus 2.3.3 (Security Testing Software) and classified as problematic. This issue affects an unknown function of the component HTTP Header Handler. The manipulation of the argument Host with the input value <script>alert(1)</script>foo leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. Impacted is integrity. The summary by CVE is:

Cross-site scripting (XSS) vulnerability in the Web UI before 2.3.4 Build #85 for Tenable Nessus 5.x allows remote web servers to inject arbitrary web script or HTML via the server header.
The advisory summarizes:
Nessus is a proprietary comprehensive vulnerability scanner which is developed by Tenable Network Security. Tenable Network Security estimates that it is used by over 75,000 organisations worldwide.

The bug was discovered 06/13/2014. The weakness was shared 10/07/2014 by Frank Lycops as File 128579 as confirmed advisory (Packetstorm). It is possible to read the advisory at packetstormsecurity.com. The vendor cooperated in the coordination of the public release. The identification of this vulnerability is CVE-2014-7280 since 10/01/2014. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. It demands that the victim is doing some kind of user interaction. Technical details as well as a public exploit are known. The attack technique deployed by this issue is T1059.007 according to MITRE ATT&CK. The advisory points out:

By setting up a malicious web server that returns a specially crafted host header, an attacker is able to execute javascript code on the machine of the person performing a vulnerability scan of the web server. No escaping on javascript code is being performed when passing the server header to the affected Web UI version via a plugin. The javascript code will be stored in the backend database, and will execute every time the target views a report that returns the server header.

A public exploit has been developed by Frank Lycops in Python and been published immediately after the advisory. The exploit is available at packetstormsecurity.com. It is declared as highly functional. The vulnerability scanner Nessus provides a plugin with the ID 88965 (Nessus Web UI Scanned Content Stored XSS), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CGI abuses : XSS. The code used by the exploit is:

#!/usr/bin/env python
import sys
from twisted.web import server, resource
from twisted.internet import reactor
from twisted.python import log

class Site(server.Site):
    def getResourceFor(self, request):
        request.setHeader('server', '&lt;script>alert(1)&lt;/script>SomeServer')
        return server.Site.getResourceFor(self, request)

class HelloResource(resource.Resource):
    isLeaf = True
    numberRequests = 0

    def render_GET(self, request):
        self.numberRequests += 1
        request.setHeader("content-type", "text/plain")
return "theSecurityFactory Nessus POC"

log.startLogging(sys.stderr)
reactor.listenTCP(8080, Site(HelloResource()))
reactor.run()

Upgrading to version 2.3.4 build#85 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (96886), Exploit-DB (34929), Tenable (88965), SecurityFocus (BID 70274†) and OSVDB (112728†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
