Resolved my issue. Clear instructions. Easy to follow. No jargon. Pictures helped. The vulnerability could allow remote code execution if an affected system received a specially crafted RPC request.
On Microsoft Windows , Windows XP, and Windows Server systems, an attacker could exploit this vulnerability without authentication to run arbitrary code.
It is possible that this vulnerability could be used in the crafting of a wormable exploit. Firewall best practices and standard default firewall configurations can help protect network resources from attacks that originate outside the enterprise perimeter. For more information, see the subsection, Affected and Non-Affected Software , in this section.
The security update addresses the vulnerability by correcting the way that the Server service handles RPC requests. For more information about the vulnerability, see the Frequently Asked Questions FAQ subsection for the specific vulnerability entry under the next section, Vulnerability Information.
Microsoft recommends that customers apply the update immediately. The following software have been tested to determine which versions or editions are affected. Other versions or editions are either past their support life cycle or are not affected. To determine the support life cycle for your software version or edition, visit Microsoft Support Lifecycle. For supported editions of Windows Server , this update applies, with the same severity rating, whether or not Windows Server was installed using the Server Core installation option.
For more information on this installation option, see Server Core. Where are the file information details? The file information details can be found in Microsoft Knowledge Base Article Is the Windows 7 Pre-Beta release affected by this vulnerability? This vulnerability was reported after the release of Windows 7 Pre-Beta. Customers running Windows 7 Pre-Beta are encouraged to download and apply the update to their systems.
On Windows 7 Pre-Beta systems, the vulnerable code path is only accessible to authenticated users. This vulnerability is not liable to be triggered if the attacker is not authenticated, and therefore would be rated Important. Security updates are also available from the Microsoft Download Center. This is not to say searching for exploited systems is a bad thing, however if the thought is somehow this is protecting the organization from an attack, this is simply wrong.
What is happening is they are attempting to detect an exploited system for one type of attack. I'm not even sure how this became a thing. Vulnerability scanners are made to identify vulnerabilities not detect compromises. This would be like having an offsite data center that you do not place any controls on, but instead you visit it once a day to see if anybody has stolen anything. Just lock up the data center. This happens more often than I wish to comment on. At this point someone might be wondering why this critical patch is different from any other.
Number one on that list is Microsoft's security bulletin of MS, and number two on that list is Rapid7's Metasploit's module for exploiting it. This is probably one of the easiest ways into a network if not the easiest way. Simply starting Metasploit loading the module and giving it an IP address of a vulnerable Windows host will get you full administrative access to that system.
The most common used tool for exploiting systems missing the MS patch is Metasploit. Metasploit has support to exploit this vulnerability in every language Microsoft Windows supports. I myself have performed penetration tests in other countries such as China, and Russia where I was able to use MS to exploit systems running Windows systems with language packs that I was unable to actually read. This vulnerability is so popular it has birthday parties thrown in its honor complete with birthday cake at the Hacker conference Derbycon.
Next year I vote we make it a surprise birthday party! Almost every notable vulnerability scanner will find unpatched MS instances on a network. This includes Rapid7's very own Nexpose scanner.
