CVSS v3.1

Official Description

openHAB, a provider of open-source home automation software, has add-ons including the visualization add-on CometVisu. Prior to version 4.2.1, the proxy endpoint of openHAB's CometVisu add-on can be accessed without authentication. This proxy-feature can be exploited as Server-Side Request Forgery (SSRF) to induce GET HTTP requests to internal-only servers, in case openHAB is exposed in a non-private network. Furthermore, this proxy-feature can also be exploited as a Cross-Site Scripting (XSS) vulnerability, as an attacker is able to re-route a request to their server and return a page with malicious JavaScript code. Since the browser receives this data directly from the openHAB CometVisu UI, this JavaScript code will be executed with the origin of the CometVisu UI. This allows an attacker to exploit call endpoints on an openHAB server even if the openHAB server is located in a private network. (e.g. by sending an openHAB admin a link that proxies malicious JavaScript.) This issue may lead up to Remote Code Execution (RCE) when chained with other vulnerabilities. Users should upgrade to version 4.2.1 of the CometVisu add-on of openHAB to receive a patch.

Technical Analysis

CVE-2024-42467 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 10.0.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
