First off thanks, Yeah, I could take time and test that one example, its a good idea, but the multi query using the semi colon is one medthod of doing SQL Injection. I'm looking for a bit more of a real answer than the anecdotal, "yup I tried it and it did not do a SQL injection, so it must be safe".
There is an issue raised in the CF bugbase - http://cfbugs.adobe.com/cfbugreport/flexbugui/cfbugtracker/main.html#bugId=78833.
* yes it's a problem (the issue is open, not closed);
* no it's not fixed.
I guess from that we can also say that since it is "verified" by Adobe we can call it at least some what "official" that Adobe has confirmed that cfinsert and cfupdate open to SQL Injection.
Too bad they did not fix that in CF9. It would be a really really simple sell for me to put time / $ it would take to update all of our older code that uses cfinsert and cfupdate to something else, towards an upgrade cost of CF9.
Shame on Adobe adobe for knowlingly releaseing CF 9 with a security issue.
I do agree with you here. But to be devil's advocate for a second: the same could be said of <cfquery>. One has to take additional measures to ensure the same vulnerabilities are mitigated with that.
I'm not sure that it's really news that these two tags are not the most well-thought-out features in the CF arsenal, and if you listen to most opinions in the community regarding <cfinsert> and <cfupdate>, it's: "don't use them".
They're great for quick and dirty insert/update processes in internal or test code, but I'd never use them in production.
It also remains a fact that any external input (form fields, URL param) must be validated as being kosher and within expected margins before they're used in any way. That is just common sense. And if one neglects to do that: one brings any eventuality onto one's self. The problem here really is with people not doing their "due diligence" on externally sourced data, not specififcally with <cfinsert>, <cfupdate> or <cfquery>.
Still: I think Adobe should make it more clear in the docs that additional measures need to be take to make them safe. And by that time... one might as well use a <cfquery> to do the SQL.
Yes, yes... I know... :-) ...
"I'm not sure that it's really news that these two tags are not the most well-thought-out features in the CF arsenal"... well said.
Its just that cfinsert and cfupdate is Sooo EZ to use. Yes, I have used a few CF ORMs, data mgr, and hand witten inserts / updates, but I keep comming back to cfinsert and cfupdate to do the simple stuff. I guess cfinsert and cfupdate and me have come to a parting of ways.
