Description:
A vulnerability has been reported in Goldlink, which can be exploited by malicious people to bypass the user authentication.

The vulnerability is caused due to an input validation error in "variables.php" when the "Acceso" function processes user credentials stored in cookies. This can be exploited via a classic SQL injection attack by inserting SQL code in "vadmin_login" and "vadmin_pass".

Successful exploitation grants access to the admin panel ("admin.php") with administrative privileges.

The vulnerability has been reported in version 3.0. Other versions may also be affected.

Solution:
Edit the source code to filter input properly.
