Title: Mambo Site Server Administrator Password Bypass Vulnerability
Severity: HIGH
Description:
Mambo Site Server is a PHP and MySQL-based tool for website content management and administration.
Versions of Mambo Site Server make insecure use of global variables in URLS used to authenticate a remote Mambo administrator, of the following form:
http://www.example.com/administrator/index2.phpPHPSESSID=1&myname=admin&fullname=admin&userid=administrator
Mambo uses the global variable PHPSESSID to determine the identity of a remote user. Since an attacker can supply any value for the fields 'userid', 'fullname' and 'myname', the credentials of the administrator can be inserted into a properly composed URL, allowing compromise of the 'administrator' ID.
This flaw allows any user to access the Mambo Server's administrative interface, leading to possible compromises of the site's function, confidentiality of data, and potentially allow a hostile user to obtain sensitive information which could be used to further compromise the host.
