[**WhiteIntel**](https://whiteintel.io) is a **dark-web** fueled search engine that offers **free** functionalities to check if a company or its customers have been **compromised** by **stealer malwares**.
Their primary goal of WhiteIntel is to combat account takeovers and ransomware attacks resulting from information-stealing malware.

On any IIS server where you get a 302 you can try stripping the Host header and using HTTP/1.0 and inside the response the Location header could point you to the internal IP address:
You can upload .config files and use them to execute code. One way to do it is appending the code at the end of the file inside an HTML comment: [Download example here](https://github.com/swisskyrepo/PayloadsAllTheThings/blob/master/Upload%20Insecure%20Files/Configuration%20IIS%20web.config/web.config)
More information and techniques to exploit this vulnerability [here](https://soroush.secproject.com/blog/2014/07/upload-a-web-config-file-for-fun-profit/)
Check the full writeup in: [https://blog.mindedsecurity.com/2018/10/from-path-traversal-to-source-code-in.html](https://blog.mindedsecurity.com/2018/10/from-path-traversal-to-source-code-in.html)
As summary, there are several web.config files inside the folders of the application with references to "**assemblyIdentity**" files and "**namespaces**". With this information it's possible to know **where are executables located** and download them.\
From the **downloaded Dlls** it's also possible to find **new namespaces** where you should try to access and get the web.config file in order to find new namespaces and assemblyIdentity.\
In **.Net MVC applications**, the **web.config** file plays a crucial role by specifying each binary file the application relies on through **"assemblyIdentity"** XML tags.
### **Exploring Binary Files**
An example of accessing the **web.config** file is shown below:
Files found in the root directory, like **/global.asax** and **/connectionstrings.config** (which contains sensitive passwords), are essential for the application's configuration and operation.
MVC applications also define additional **web.config files** for specific namespaces to avoid repetitive declarations in each file, as demonstrated with a request to download another **web.config**:
The mention of a custom namespace hints at a DLL named "**WebApplication1**" present in the /bin directory. Following this, a request to download the **WebApplication1.dll** is shown:
In a scenario where a DLL imports a namespace called **WebApplication1.Areas.Minded**, an attacker might infer the existence of other web.config files in predictable paths, such as **/area-name/Views/**, containing specific configurations and references to other DLLs in the /bin folder. For example, a request to **/Minded/Views/web.config** can reveal configurations and namespaces that indicate the presence of another DLL, **WebApplication1.AdditionalFeatures.dll**.
In order to access the web page you could take a look to the served **SSL Certificate** and maybe you can find the domain/subdomain name in there. If it isn't there you may need to **brute force VHosts** until you find the correct one.
The main limitation of this technique if the server is vulnerable is that **it can only find up to the first 6 letters of the name of each file/folder and the first 3 letters of the extension** of the files.
You can use [https://github.com/irsdl/IIS-ShortName-Scanner](https://github.com/irsdl/IIS-ShortName-Scanner) to test for this vulnerability:`java -jar iis_shortname_scanner.jar 2 20 http://10.13.38.11/dev/dca66d38fd916317687e1390a420c3fc/db/`

ASP.NET include a debugging mode and its file is called `trace.axd`.
It keeps a very detailed log of all requests made to an application over a period of time.
This information includes remote client IP's, session IDs, all request and response cookies, physical paths, source code information, and potentially even usernames and passwords.
However, some people will use the **default values** of these parameters and will use as **cookie the email of the user**. Therefore, if you can find a web using the **same platform** that is using the ASPXAUTH cookie and you **create a user with the email of the user you want to impersonate** on the server under attack, you may be able to us**e the cookie from the second server in the first one** and impersonate the user.\
[Full report here](https://blog.orange.tw/2022/08/lets-dance-in-the-cache-destabilizing-hash-table-on-microsoft-iis.html): A bug in the code **didn't properly check for the password given by the user**, so an attacker whose **password hash hits a key** that is already in the **cache** will be able to login as that user .
