Vulnerability	90027	High Risk Ports Open	3 Systems	High Risk

Description	The following high risk ports are open: [For specific url or description click server link below.] It is generally not recommended to expose these ports to the Internet as they may be used as attack vectors. If access to these services from remote sites is required, tunnelling or a VPN would be recommended instead of exposing these ports. Note: Even if the ports are immediately closed after being opened, this is still a security risk as packets are reaching the destination host. It is recommended to completely drop packets from untrusted sources instead.
Solution	Ensure that the ports are filtered by your router or firewall or close the ports on the affected systems.
Category	Hosting or infrastructure flaw.

Vulnerability	90139	Script Allows Arbitrary Command Execution	1 System	High Risk

Description	One or more scripts on this host appear to execute commands which can be manipulated by remote users. This flaw may allow arbitrary commands to be executed with the same privileges as the web server. A remote attacker could exploit this flaw to compromise the system. Under some circumstances it may be possible for attacker to elevate the privileges gained though the exploitation of local system flaws. An example that demonstrates this is: [For specific url or description click server link below.] This is simply an example that illustrates the problem, you should fix the underlying issue rather than attempting to prevent this exploit from working.
Solution	Recode the web application to ensure that unsanitised user supplied input is never included in executable statements.
Category	Application or content flaw.

Vulnerability	11139	Script Appears Vulnerable to SQL Injection	1 System	High Risk

Description	One or more scripts on this host appear vulnerable to an SQL injection attack. By requesting the page with parameters containing particular SQL commands, it is possible to force a database level error or otherwise demonstrate that the database is executing user supplied code. This implies that the parameter is being passed to the database without proper input validation. A maliciously crafted parameter could modify the contents of the database, damage it, extract hidden information, allow an attacker to login without a password or allow execution of arbitrary system commands, depending on the type of database. The issue can be demonstrated as follows: [For specific url or description click server link below.] This is simply an example that illustrates the problem, you should fix the underlying injection issue rather than attempting to prevent this exploit from working. Note: Users of Microsoft Internet Explorer may need to disable the 'Show Friendly HTTP Error Messages' option in the Advanced tab of the options dialog in order to see the example properly.
Solution	Use bound parameters (also known as parameterised commands) and improve input validation in the web application source code.
Category	Application or content flaw.

Vulnerability	10815	Cross-Site Scripting	1 System	Medium Risk

Description	This system is running a web server or web application which is vulnerable to Cross-Site Scripting (XSS) attacks. Certain pages include user-supplied input in the response and HTML special characters are not escaped. An attacker could use this to inject malicious JavaScript or HTML code, which will run at the same trust level as the server. This may enable them to steal session cookies, form details, etc. An example that demonstrates this is: [For specific url or description click server link below.] This is simply an example that illustrates the problem, you should fix the underlying issue rather than attempting to prevent this exploit from working. Note: This vulnerability must be addressed server-side. Adding JavaScript (client-side) validation on form fields does not offer any protection against Cross-Site Scripting or other attacks.
Solution	Recode your web application to ensure all user supplied input is escaped when displayed, or contact your web application vendor for a patch. Any JavaScript-based fix will not be effective.
Category	Application or content flaw.

Vulnerability	90072	Script Allows Arbitrary Redirection	1 System	Medium Risk

Description	It is possible to craft a URL which appears to be located on this site, but will redirect users to an arbitrary location. This site could then pose as the legitimate site and prompt users to provide sensitive information. It could also contain any other type of malicious content. The following is an example of a URL which will redirect you to another site: [For specific url or description click server link below.]
Solution	Recode scripts to allow redirections only to specific locations, for example limit redirections to your own domain.
Category	Application or content flaw.

Vulnerability	90091	XPath Injection	1 System	Medium Risk

Description	One or more scripts on this host appear vulnerable to XPath injection attacks. By requesting a page with parameters containing particular XPath elements, it is possible to force an XPath error or otherwise demonstrate that the user supplied code is being interpreted as XPath statements. This implies that a parameter is being passed to an XPath interpreter without proper input validation. A maliciously crafted parameter might be able to extract hidden information, bypass login requirements or even perform code execution depending on the XPath parser used. The issue can be demonstrated as follows: [For specific url or description click server link below.] This is simply an example that illustrates the problem, you should fix the underlying injection issue rather than attempting to prevent this exploit from working.
Solution	Perform input validation within the web application and utilise query parameterisation where supported by the XPath parser.
Category	Application or content flaw.

Vulnerability	12217	DNS Cache Snooping	1 System	Low Risk

Description	This system is running a DNS server that accepts queries from any address (although recursive queries may be disabled). The name server responds differently for domains that have recently been looked-up. An attacker could use this to determine if certain sites have been visited by users of this nameserver.
Solution	Restrict access to DNS caches to local users. For Bind, use the "AllowQuery" directive.
Category	Hosting or infrastructure flaw.

Vulnerability	90001	Holes Detected in Firewall Configuration	1 System	Low Risk

Description	This system is protected by a firewall which blocks access to TCP ports in inconsistent ways. Incoming TCP connections to most ports are simply dropped, however some ports were discovered where the connection is actively refused, for example with a TCP RST. This often indicates a firewall configuration error, and commonly occurs when the configuration has not been altered in line with changing system configuration behind the firewall. For example when a service such as a mail server is removed, but the corresponding firewall rule is not. The TCP ports which actively refuse connections are: [For specific url or description click server link below.]
Solution	Reconfigure your firewall to completely drop all connections on ports that you are not running services on.
Category	Hosting or infrastructure flaw.
