Iis rewrite allows unwanted redirects from URL parameter

Question

1.00/5 (1 vote)

See more:

We have an ASP.NET Core 7 MVC app hosted on Azure and IIS. For some purposes, like adding a trailing slash, we use URL rewrites. But this rule appears to cause a problem with unwanted redirects from URL parameter, so for example, https://example.com/http:/google.com will redirect to the Google site.

What happens is this: when the request enters the RewriteModule, it's looks like this:

http://rockstar-dev-web-01:80/http:/google.com

(a bit obfuscated, but you get the idea), but then it appears to be split on it's own into two parts and the second one is being processed. Once it hits the add the trailing slash rewrite, a 301 redirect is made. Here are logs to illustrate this behavior, as you can see it the end only the latter part of the URL is being processed:

What I have tried:

I have removed the rewrite rule and it doesn't allow anymore redirects, but that's not a long-term option. I have also tried to reshuffle the order of rewrites, but to no success - the problem still persists.

How to fix this problem?

IIS and the rewrite module won't do this by themselves. You must have set up a rewrite rule that's doing it.

But since you haven't shown us any of your rewrite rules, we can't tell you what the problem is.

Hello Richard, thanks for reply. I have updated the post with all of our rewrites (there are many).

Solution 1

Assuming it's the "Add trailing slash" rule that's causing the problem, your match is missing the "start of line" anchor:

XML

<match url="(.*[^/])$" ignoreCase="true"/>

should be:

XML

<match url="^(.*[^/])$" ignoreCase="true"/>

Looking at logs this rule is responsible for creating a redirect for sure, because, when an request URL such as "https://example.com/http:/google.com" enters the pipeline, first, before any rewrite rule is being evaluated, get shorted to just "http:/google.com". Then, when it reaches the mentioned trailing slash rule, the address is changed into "http:/google.com/" with a slash at the end and the redirect is being made. Adding the anchor unfortunately didn't change the outcome.
