Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-40598 is a reflected cross-site scripting (XSS) vulnerability found in the SMA100 series web interface. It allows a remote, unauthenticated attacker to potentially execute arbitrary JavaScript code. The vulnerability is located in the `radiusChallengeLogin` endpoint and can be triggered by injecting a malicious JavaScript code via the `state` parameter. The injected code is reflected directly into the response without any filtering. The SMA100's built-in web application firewall (WAF) appears to be inactive on management interfaces, which means even basic XSS payloads can be successful. An attacker can inject malicious code into a web page, which will then run in a user's browser if they visit a specially crafted link.

Description: A Reflected cross-site scripting (XSS) vulnerability exists in the SMA100 series web interface, allowing a remote unauthenticated attacker to potentially execute arbitrary JavaScript code.
