ETIC Telecom Remote Access Server Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in all versions of ETIC Telecom Remote Access Server (RAS) prior to 4.5.0. This vulnerability allows attackers to inject malicious scripts into web pages viewed by users. The issue arises because the ETIC RAS web server dynamically generates pages that reflect client-side input without proper validation, particularly in the method parameter.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where an attacker can inject malicious scripts that are executed in the context of the user's browser.

Remediation

Users are advised to update to version 4.5.0 or later, where this vulnerability has been fixed. For versions prior to 4.5.0, ETIC Telecom recommends ensuring that the administration web page is accessible only through the LAN side over HTTPS and is protected with authentication.
