Description
A weakness has been identified in Intelliants Subrion CMS up to 4.2.1. This vulnerability affects the function iaUsers::authorize of the file front/login.php of the component Login Page. This manipulation of the argument $_SERVER['HTTP_REFERER'] causes open redirect. The attack is possible to be carried out remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
An open redirect vulnerability has been identified in Intelliants Subrion CMS versions through 4.2.1. The issue arises in the Login Page component, specifically within the function iaUsers::authorize in the file front/login.php. The vulnerability is caused by the improper validation of the HTTP_REFERER header, allowing remote attackers to manipulate the referer value and redirect users to arbitrary external sites after login. This exploitation takes advantage of the application's session management and can be executed remotely.
It is recommended to validate the HTTP_REFERER header against a strict allowlist of trusted schemes and hosts, or to implement a same-origin policy. If validation fails, redirect users to a fixed local profile or dashboard page.
