漏洞描述:
Introduction:
Although IIS5 is very old, finding one is not impossible! Therefore, I want to introduce a technique to bypass the IIS authentication methods on a directory.
Although IIS5 is very old, finding one is not impossible! Therefore, I want to introduce a technique to bypass the IIS authentication methods on a directory.
This vulnerability is because of using Alternate Data Stream to open a protected folder. All of IIS authentication methods can be circumvented. In this technique, we can add a “:$i30:$INDEX_ALLOCATION” to a directory name to bypass the authentication.
It is possible to run “secretfile.asp” by using:
“/AuthNeeded:$i30:$INDEX_ALLOCATION/secretfile.asp”
Instead of:
“/AuthNeeded/secretfile.asp”
