Vulnerabilities: 5 (High:0 Medium:3 Low:2)

Vulnerability 10815 Cross-Site Scripting 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:
https://192.168.0.102/x/<script>alert("vulnerable!")</script>
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 10539 Globally Useable Name Server   SANS Medium Risk
Description This system is running a name server that allows any system on the Internet to perform recursive queries and resolve third-party domain names. A remote attacker could use this to extract information about your name lookup patterns, and may be able to perform DNS cache poisoning attacks. 
Solution Restrict recursive queries to trusted addresses. For servers running BIND, use the allow-recursion or allow-query directives. 
Category Hosting or infrastructure flaw.

First Found 13 May 2010 Port 53/udp Last 6 Months

Vulnerability 10882 SSH Protocol Version 1 Enabled Medium Risk
Description This system is running an SSH service with SSH protocol version 1 enabled. This version of the protocols is not completely cryptographically secure. A passive eavesdropper could use these weaknesses to extract information such as the lengths of passwords and commands. 
Solution Configure your SSH service to only use protocol version 2. For OpenSSH, set the 'Protocol' option to '2'. 
Category Hosting or infrastructure flaw.

First Found 13 January 2011 Port 22/tcp Last 6 Months

Vulnerability 12217 DNS Cache Snooping 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. A remote 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 11213 TRACE and/or TRACK Methods Enabled Low Risk
Description This system supports the HTTP TRACE and/or TRACK methods. These increase the exploitability of any cross-site scripting vulnerabilities that may exist in your site. As they are primarily intended for debugging, they can be turned off without reduction of service. 
Solution Disable these methods on production servers.
IIS6, IIS7: Use the URLScan Security tool
IIS5: Use the IIS Lockdown tool
Apache: Use mod_rewrite to redirect unallowed verbs to the forbidden target, or with newer versions use the configuration option 'TraceEnable off'. 
Category Hosting or infrastructure flaw.

Vulnerabilities Fixed Since Last Month: 3 (High:1 Medium:2 Low:0)

Vulnerability 90027 High Risk Ports Open High Risk
Description The following high risk ports are open:
PORT      SERVICE
135/tcp   msrpc
137/tcp   netbios-ns
139/tcp   netbios-ssn
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 11793 Apache < 1.3.28 Multiple flaws Medium Risk
Description According to its banner, this web server is running a version of Apache older than 1.3.28. This version contains fixes for multiple minor denial of service flaws. Although these are not exploitable in all configurations, it is recommended that you upgrade to the latest version. 
Solution Upgrade to an unaffected version. 
Category Hosting or infrastructure flaw.

First Found 13 March 2011 Port No information available Last 6 Months

Vulnerability 10736 DCE Services Enumeration Medium Risk
Description It is possible for any remote user to connect to port 135 on this host and enumerate the available DCE services. The information leaked is relatively low risk, although an attacker could use it to focus their strategy. However, the vulnerability is more worrying because it shows that Windows file sharing (NetBIOS) is accessible over the internet, which is considered unwise.
 
Solution Use a firewall to restrict access to Windows file sharing ports to trusted addresses. 
Category Hosting or infrastructure flaw.
