THIS IS A GENUINE ISOWAREZ RELEASE
Title: Microsoft IIS 6.0 with PHP installed Authentication Bypass
Affected software:
Microsoft IIS 6.0 with PHP installed
(tested on Windows Server 2003 SP1 running PHP5)
Details:
By sending a special request to the IIS 6.0 Service running PHP the attacker can
successfully bypass access restrictions.
Take for example:
1.) IIS/6.0 has PHP installed
2.) There is a Password Protected directory configured
–> An attacker can access PHP files in the password protected
directory and execute them without supplying proper credentials.
–> Example request (path to the file): /admin::$INDEX_ALLOCATION/index.php
Title: Microsoft IIS 7.5 Classic ASP Authentication Bypass
Affected Software:
Microsoft IIS 7.5 with configured Classic ASP and .NET Framework 4.0
installed (.NET Framework 2.0 is unaffected, other .NET frameworks
have not been tested)
(tested on Windows 7)
Details:
By appending ":$i30:$INDEX_ALLOCATION" to the directory serving the
classic ASP file access restrictions can be successfully bypassed.
Take this Example:
1.) Microsoft IIS 7.5 has Classic ASP configured (it allows serving .asp files)
2.) There is a password protected directory configured that has
administrative asp scripts inside
3.) An attacker requests the directory with :$i30:$INDEX_ALLOCATION
appended to the directory name
4.) IIS/7.5 gracefully executes the ASP script without asking for
proper credentials
Title: Microsoft IIS 7.5 .NET source code disclosure and authentication bypass
Affected Software:
Microsoft IIS/7.5 with PHP installed in a special configuration
(Tested with .NET 2.0 and .NET 4.0)
(tested on Windows 7)
The special configuration requires the "Path Type" of PHP to be set to
"Unspecified" in the Handler Mappings of IIS/7.5
Details:
The authentication bypass is the same as the previous vulnerabilities:
Requesting for example
http://<victimIIS75>/admin:$i30:$INDEX_ALLOCATION/admin.php will run
the PHP script without asking for proper credentials.
By appending /.php to an ASPX file (or any other file using the .NET
framework that is not blocked through the request filtering rules,
like misconfigured: .CS,.VB files)
IIS/7.5 responds with the full source code of the file and executes it
as PHP code. This means that by using an upload feature it might be
possible (under special circumstances) to execute arbitrary PHP code.
Example: Default.aspx/.php
