(*): ISC rating
- We use 4 levels:
- PATCH NOW: Typically used where we see immediate danger of exploitation. Typical environments will want to deploy these patches ASAP. Workarounds are typically not accepted by users or are not possible. This rating is often used when typical deployments make it vulnerable and exploits are being used or easy to obtain or make.
- Critical: Anything that needs little to become "interesting" for the dark side. Best approach is to test and deploy ASAP. Workarounds can give more time to test.
- Important: Things where more testing and other measures can help.
- Less Urgent: Typically we expect the impact if left unpatched to be not that big a deal in the short term. Do not forget them however.
- The difference between the client and server rating is based on how you use the affected machine. We take into account the typical client and server deployment in the usage of the machine and the common measures people typically have in place already. Measures we presume are simple best practices for servers such as not using outlook, MSIE, word etc. to do traditional office or leisure work.
- The rating is not a risk analysis as such. It is a rating of importance of the vulnerability and the perceived or even predicted threat for affected systems. The rating does not account for the number of affected systems there are. It is for an affected system in a typical worst-case role.
- Only the organization itself is in a position to do a full risk analysis involving the presence (or lack of) affected systems, the actually implemented measures, the impact on their operation and the value of the assets involved.
- All patches released by a vendor are important enough to have a close look if you use the affected systems. There is little incentive for vendors to publicize patches that do not have some form of risk to them.
(**): The exploitability rating we show is the worst of them all due to the too large number of ratings Microsoft assigns to some of the patches.

I found an improvement though: somehow you've partially mixed up MS11-096 (Excel, KB2640241, important) with MS10-046 (Shell, KB2286198, critical).
MS11-096 applies to Excel from Office 2003 SP3 (and probably all older versions). Although a crafted Excel file sent by e-mail or provided on a web site allows for remote code execution (user interaction required), MS11-096 is rated "important" by Microsoft.

The rating from Microsoft is dependent on how important they think the product is. Office 2003 is old, so it can probably never get any more critical exploits. It is important to keep this in mind when reading the MS rating.
Old or small market products (BizTalk, Commerce Server etc) will probably not get critical unless their is an active exploit in the wild. They do not want to scare their mainstream customers.

Exploits in the wild, current attack vectors and attack runs means little to MS.

Remote code execution on a DC with “Exploit code likely” <- read reliably exploitable. Or is just the fact that some domain credentials are needed and that there may be a firewall somewhere reason to rate it only important? Interested to see what your thoughts are on this.
