This is exactly right.

The server log is not encrypted when using TLS, which is one reason you want to keep sensitive information out of your URLs.

You have no way of knowing what they log and don't log. If their server logs are compromised, you should be assuming their username/password database was as well.

And HTTPS requests are encrypted. The whole request, including the "GET /someurl&password=s33krit HTTP/1.1" part. As I said, using POST doesn't add any additional security to this.

I don't understand the point you're trying to make here, or the stridency with which you're making it. You in fact do know that the most popular web servers do log the URL, and do not log POST parameters or individual headers.

That's why professional security audits will ding you for putting anything sensitive in a URL.

Actually, we ding you for putting sensitive information in URLs that are used in a browser. The reason is that it will then be sent to other sites in the referrer header. When it is used for an API it doesn't matter. A security audit will check that logs are not logging sensitive information or that they are properly secured and encrypted if they do contain such information. The combination of telling users to put their password into the url and logging the url would be a problem, but not either thing on its own.

No, SomeOtherGuy. This is an HTTPS site. The referer header does not behave the way you're implying it does on HTTPS sites.

And having read and written this particular audit line item about 29074894389734897 times in the last 15 years, let me assure you that logging is clearly an issue.

The bit about how "if someone can see your logs you're already boned" is also message-board-logic more than reality. Logs are shipped all over the place. On a network pentest, one of the things you do when you pop a box is hunt for logs; even after you get root on the machine, you don't automatically have all the passwords that get stuck in the log files. Same goes for all the random LogLogic-style consoles those logs get fed to.

If you have more questions about this stuff, my contact info is in my profile --- just click my username above this comment. I just wanted to chime in to say that 'carbocation was exactly right, but my comments are now repeating themselves, and so I'm done on this thread.

I agree with your concerns. But my comment was talking about "typical server logs" and HTTPS-POST vs HTTP-GET, while yours is addressing different issues.

I addressed why what gets in logs doesn't matter: if their server is compromised you have to assume you are boned anyways. And I don't understand why is your comment would be talking about "HTTP-GET"? The API in question is dealing with HTTPS for both GET and POST requests.

I don't understand why your comments pointing out details of the http spec and common-sense security considerations are being downvoted. I guess they are coming across as overly 'stident'? Anyway, I've found them helpful. Thanks.
