Part 3: Adobe hotfix released for "Serious security threat for ColdFusion servers"

Note: This blog post is from 2013. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
Adobe has come out with a new security hotfix for a very serious attack on ColdFusion servers which had hit many (perhaps most) CF shops over the past couple of weeks, and it's vital that all shops apply that fix. (Even if you think you've protected yourself in other ways

There is a new Adobe CF blog entry pointing to the new hotfix, and I point that out rather than the technote for the hotfix itself, because as often is the case, there has been some useful discussion related to applying the fix. Indeed, there's a warning I've shared there about a problem (hopefully temporary) with the hotfix file for users of ColdFusion 9.0.2. (Update: the confusion about 9.0.2 is resolved. The technote has been corrected. See the comments in the Adobe blog entry for more details.)

Users of ColdFusion 10, 9.0.2, 9.0.1, and 9.0 should certainly proceed to implement the fix.

I address several questions and other observations about this hotfix below.

Part 2: Serious security threat for ColdFusion servers [now covered by a hotfix]

Note: This blog post is from 2013. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
Since I posted my entry earlier today about a Serious security threat for #ColdFusion servers [not now covered by a hotfix], I have had many questions and discussions which lead me to share more info.

At first I was adding these as updates to the previous entry, but I fear that some who may have read it earlier in the day may then miss some of this new info, thus this "Part 2". You will definitely want to read part 1 before proceeding here.

[Update: And since writing this entry 2 weeks ago, Adobe has indeed now come out with a hotfix. I have more to say about that in the new Part 3: Adobe hotfix released for "Serious security threat for #ColdFusion servers". While you should proceed to get that fix in place, you'll likely benefit from reading parts 1, 2, and 3, as there's more discussed than just the thread and fix, itself, which could benefit you down the road.]

Among the new information shared below are such things as how the hack worked (not too much detail, though), how to determine what the exploit may have exposed, how to handle resolving things for many sites via scripting, how to lock down the /adminapi, /administrator, and /componentutils directories, and most important, why you should not skip all this just because "we already block all access to the CFIDE/adminapi" (and /administrator and /componentutils)". There may be exposure you're not considering.

Serious security threat for ColdFusion servers [now covered by a hotfix]

Note: This blog post is from 2013. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
Hey folks, there's a fairly serious security threat out in the wild, and you may want to check if your server's been hit. (It may be old news to some, but for now it's hitting people in the past week or so.) It's been confirmed to have hit at least CF9 (9.01 and 9.0.2) servers, but it seems it would apply to as well to CF10 or down to CF 7, as it leverages the Admin API.

And note that it's NOT one that you're protected against by having applied CF security hotfixes. (Updated Jan 15 2013, as Adobe now has a hotfix for this. More below.)

There's quite a bit for you to consider regarding this recent threat, as I discuss here.
