We were drawn to researching the security aspect of the framework due to its popularity, with the goal of contributing to a safer internet. In this first article, we demonstrate how an unauthenticated attacker can leverage a vulnerability with a supposedly low impact to gain full control over the Moodle instance. --------------------------------------------- https://www.sonarsource.com/blog/playing-dominos-with-moodles-security-1/ ∗∗∗ A broken marriage.

This is usually facilitated through the MIT or Heimdal Kerberos stacks. Kerberos is designed as an authentication-based protocol therefore authorisation decisions are implemented independently to the Kerberos protocol itself. Due to this, different vendor stacks behave differently on how authorisation decisions are made. --------------------------------------------- https://www.pentestpartners.com/security-blog/a-broken-marriage-abusing-mix… ∗∗∗ A Beginner’s Guide to Adversary Emulation with Caldera ∗∗∗ --------------------------------------------- The target audience for this blog post is individuals who have a basic understanding of cybersecurity concepts and terminology and looking to expand their knowledge on adversary emulation.

Publicly accessible MS-SQL servers with simple passwords are one of the main attack vectors used when targeting Windows systems. Typically, threat actors target poorly managed MS-SQL servers and attempt to gain access through brute force or dictionary attacks. If successful, they install malware on the infected system. --------------------------------------------- https://asec.ahnlab.com/en/56350/ ∗∗∗ Stories from the SOC - Unveiling the stealthy tactics of Aukill malware ∗∗∗ --------------------------------------------- On April 21st, 2023, AT&T Managed Extended Detection and Response (Managed XDR) investigated an attempted ransomware attack on one of our clients, a home improvement business. The investigation revealed the attacker used AuKill malware on the clients print server to disable the servers installed endpoint detection and response (EDR) solution by brute-forcing an administrator account and downgrading a driver to a vulnerable version. --------------------------------------------- https://cybersecurity.att.com/blogs/security-essentials/stories-from-the-so… ===================== = Vulnerabilities = ===================== ∗∗∗ Maxon Cinema 4D SKP File Parsing vulnerabilities ∗∗∗ --------------------------------------------- CVSS Score: 7.8 CVE-2023-40482, CVE-2023-40483, CVE-2023-40486, CVE-2023-40485, CVE-2023-40484, CVE-2023-40488, CVE-2023-4049[0], CVE-2023-40491, CVE-2023-40487, CVE-2023-40489 Mitigation: Given the nature of the [vulnerabilities], the only salient mitigation strategy is to restrict interaction with the application. --------------------------------------------- https://www.zerodayinitiative.com/advisories/published/ ∗∗∗ (0Day) LG Simple Editor vulnerabilities ∗∗∗ --------------------------------------------- CVSS Scores: 6.5-9.8 CVE-2023-40502, CVE-2023-40513, CVE-2023-40514, CVE-2023-40515, CVE-2023-40492, CVE-2023-40493, CVE-2023-40494, CVE-2023-40495, CVE-2023-40496, CVE-2023-40497, CVE-2023-40498, CVE-2023-40499, CVE-2023-40500, CVE-2023-40503, CVE-2023-40503, CVE-2023-40504, CVE-2023-40505, CVE-2023-40506, CVE-2023-40507, CVE-2023-40508, CVE-2023-40509, CVE-2023-40510, CVE-2023-40511, CVE-2023-40512, CVE-2023-40501, CVE-2023-40516 [...] they do not have plans to fix the [vulnerabilities] --------------------------------------------- https://www.zerodayinitiative.com/advisories/published/ ∗∗∗ (0Day) LG SuperSign Media Editor vulnerabilities ∗∗∗ --------------------------------------------- CVSS Scores: 5.3-7.5 CVE-2023-40517, CVE-2023-41181 The vendor states that they do not have plans to fix the [vulnerabilities] now or in the future.
