Vulnerability Title
CometVisu Backend for openHAB affected by SSRF/XSS
Vulnerability 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.

Vulnerability Title
openHAB 安全漏洞
Vulnerability Description
openHAB是openHAB开源的一款家庭自动化应用程序。 openHAB 4.2.1之前版本存在安全漏洞，该漏洞源于无需身份验证即可访问附加组件的代理端点，在非私有网络中，此代理功能可用作服务器请求伪造，以诱导对内部服务器的GET HTTP请求。此代理还可用作跨站脚本攻击，即使服务器位于私有网络中，仍允许攻击者利用服务器上的调用端点。
