[原文]SQL injection vulnerability in the bblogin function in functions.php in PHP-Nuke 6.x through 7.2 allows remote attackers to bypass authentication and gain access by injecting base64-encoded SQL code into the user parameter.
Reportedly PHP-Nuke is prone to multiple SQL injection vulnerabilities. These issues are due to a failure of the application to properly sanitize user supplied input.
As a result of these issues an attacker could modify the logic and structure of database queries. Other attacks may also be possible, such as gaining access to sensitive information.
To read arbitrary users private messages:
To create an arbitrary administrator account with username "waraxe2" and password "coolpass":
PHP-Nuke functions.php user Parameter SQL Injection
Remote / Network Access
Loss of Confidentiality,
Loss of Integrity
PHP-Nuke contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the 'functions.php' script not properly sanitizing user-supplied input to the 'user' parameter. This may allow an attacker to inject or manipulate SQL queries in the back-end database, allowing for the manipulation or disclosure of arbitrary data.
