Authentication Bypass in iisPROTECT
<http://www.iisprotect.com/> iisPROTECT is designed to provide password
protection to web directories similar to the htaccess method utilized by
the Apache Software Foundation's HTTP web server. A vulnerability in the
product allows bypassing the protection mechanism.
* iisPROTECT version 2.1 and 2.2
* iisPROTECT version 18.104.22.168
Upon successful installation and implementation of iisPROTECT, users will
be presented with a login and password dialog box when attempting to
access files contained in a protected directory.
Consider the following example:
An attacker can bypass this authentication by simply requesting the same
file through different URL-encoded representations. Examples of these
include but are not limited to:
