### Summary 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. ### Details The 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....

IntroductionIn a previous article, I demonstrated how to configure the Automatic Certificate Management Environment (ACME) feature included in the Identity Management (IdM) Dogtag Certificate Authority (CA). Specifically, I covered installation of IdM with random serial numbers, and how to enable the ACME service and expired certificate pruning. This article explains the management of ACME (currently a technology preview) with IdM and Red Hat Enterprise Linux (RHEL) clients.Currently, mod_md is the only ACME client implementation completely supported and provided by Red Hat. For this article,

Cybersecurity researchers have uncovered a new Linux rootkit called PUMAKIT that comes with capabilities to escalate privileges, hide files and directories, and conceal itself from system tools, while simultaneously evading detection. "PUMAKIT is a sophisticated loadable kernel module (LKM) rootkit that employs advanced stealth mechanisms to hide its presence and maintain communication with
