SCA: security update for uptime-kuma (GHSA-2qgm-m29m-cj2h)

medium Tenable Cloud Security Plugin ID 409042

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Uptime Kuma is an open source, self-hosted monitoring tool. An **Improper URL Handling Vulnerability**
 allows an attacker to access sensitive local files on the server by exploiting the `file:///` protocol.
 This vulnerability is triggered via the **"real-browser"** request type, which takes a screenshot of the
 URL provided by the attacker. By supplying local file paths, such as `file:///etc/passwd`, an attacker can
 read sensitive data from the server. This vulnerability arises because the system does not properly
 validate or sanitize the user input for the URL field. Specifically: 1. The URL input (`<input
 data-v-5f5c86d7="" id="url" type="url" class="form-control" pattern="https?://.+" required="">`) allows
 users to input arbitrary file paths, including those using the `file:///` protocol, without server-side
 validation. 2. The server then uses the user-provided URL to make a request, passing it to a browser
 instance that performs the "real-browser" request, which takes a screenshot of the content at the given
 URL. If a local file path is entered (e.g., `file:///etc/passwd`), the browser fetches and captures the
 file’s content. Since the user input is not validated, an attacker can manipulate the URL to request local
 files (e.g., `file:///etc/passwd`), and the system will capture a screenshot of the file's content,
 potentially exposing sensitive data. Any **authenticated user** who can submit a URL in "real-browser"
 mode is at risk of exposing sensitive data through screenshots of these files. This issue has been
 addressed in version 1.23.16 and all users are advised to upgrade. There are no known workarounds for this
 vulnerability. (CVE-2024-56331)
