Talos set up an internet server to log all activity related to this name, and immediately we received a barrage of HTTP requests from systems running Microsoft’s “System Center Configuration Manager.” [..] we were able to masquerade as a trusted system. Networks using .kids names could be tricked into trusting our system to relay internal mail, dictate configuration management settings, and more. --------------------------------------------- https://blog.talosintelligence.com/whats-in-a-name/ ∗∗∗ Inconsistencies in the Common Vulnerability Scoring System (CVSS) ∗∗∗ --------------------------------------------- The goal of CVSS is to provide comparable scores across different evaluators. However, previous works indicate that CVSS might not reach this goal: If a vulnerability is evaluated by several analysts, their scores often differ. This raises the following questions: Are CVSS evaluations consistent? Which factors influence CVSS assessments? We systematically investigate these questions in an online survey with 196 CVSS users. --------------------------------------------- https://www.schneier.com/blog/archives/2023/09/inconsistencies-in-the-commo… ∗∗∗ CVE-2023-4634 - Tricky Unauthenticated RCE on Wordpress Media Library Assistant Plugin using a good old Imagick ∗∗∗ --------------------------------------------- As discussed in many of our articles, you already know that WordPress and related plugins are taking up a large space in the global attack surface [..] The vulnerability described below is a perfect example --------------------------------------------- https://patrowl.io/blog-wordpress-media-library-rce-cve-2023-4634/ ∗∗∗ When URL parsers disagree (CVE-2023-38633) ∗∗∗ --------------------------------------------- Discovery and walkthrough of CVE-2023-38633 in librsvg, when two URL parser implementations (Rust and Glib) disagree on file scheme parsing leading to path traversal. --------------------------------------------- https://www.canva.dev/blog/engineering/when-url-parsers-disagree-cve-2023-3… ∗∗∗ Vorsicht vor betrügerischen PayPal-Anrufen ∗∗∗ --------------------------------------------- Ihr Telefon klingelt.
