Technical Description

Multiple vulnerabilities were identified in AlstraSoft Affiliate Network Pro, which could be exploited by remote attackers to execute arbitrary commands, or conduct cross site scripting and SQL injection attacks.

The first flaw is due to an input validation error in the "login_validate.php" script that does not properly filter specially crafted "login", "password", and "flag" parameters, which may be exploited by malicious users to conduct SQL injection attacks and gain unauthorized access to the administration interface.

The second issue is due to an input validation error in the "admin_options_manage.php" script that does not properly validate the "number" parameter, which could be exploited by attackers to execute arbitrary PHP commands.

The third vulnerability is due to input validation errors in "index.php" and "admin/index.php" when processing specially crafted "err", "firstname", and "lastname" variables, which may be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser.

The fourth issue is due to input validation errors in various scripts when called directly via the browser, which may be exploited by attackers to determine the installation path.
