Technical Details of CVE-2023-36386

This section delves into the technical aspects of the CVE-2023-36386 vulnerability in Siemens RUGGEDCOM devices.

Vulnerability Description

The vulnerability arises due to a lack of input sanitization in the web interface of the affected applications. Attackers can exploit this weakness by crafting malicious links that, when clicked by users, execute unauthorized JavaScript code.

Affected Systems and Versions

Siemens RUGGEDCOM devices impacted by this vulnerability include RUGGEDCOM ROX MX5000, RX1400, RX1500, RX1501, RX1510, RX1511, RX1512, RX1524, RX1536, and RX5000, all running versions lower than V2.16.0.

Exploitation Mechanism

Attackers can carry out an XSS attack by coercing users to click on specially crafted links that embed malicious JavaScript code. When users interact with these links, the injected code executes within the context of the victim's session, potentially compromising the device.
