What a Cluster: Local Volumes Vulnerability in Kubernetes
- Akamai security researcher Tomer Peled recently discovered a high-severity vulnerability in Kubernetes that was assigned CVE-2023-5528 with a CVSS score of 7.2. The vulnerability allows remote code execution with SYSTEM privileges on all Windows endpoints within a Kubernetes cluster. To exploit this vulnerability, the attacker needs to apply malicious YAML files on the cluster. This vulnerability can lead to full takeover on all Windows nodes in a cluster. This vulnerability can be exploited on default installations of Kubernetes (earlier than version 1.28.4), and was tested against both on-prem deployments and Azure Kubernetes Service. In this blog post, we provide a proof-of-concept YAML file as well as an Open Policy Agent (OPA) rule for blocking this vulnerability.

Magnet Goblin Targets Publicly Facing Servers Using 1-Day Vulnerabilities
- Magnet Goblin is a financially motivated threat actor that quickly adopts and leverages 1-day vulnerabilities in public-facing services as an initial infection vector. At least in one case of Ivanti Connect Secure VPN (CVE-2024-21887), the exploit entered the group’s arsenal as fast as within 1 day after a POC for it was published. Campaigns that we were able to attribute to this actor targeted Ivanti, Magento, Qlink Sense and possibly Apache ActiveMQ. Analysis of the actor’s recent Ivanti Connect Secure VPN campaign revealed a novel Linux version of a malware called NerbianRAT, in addition to WARPWIRE, a JavaScript credential stealer. * The actor’s arsenal also includes MiniNerbian, a small Linux backdoor, and remote monitoring and management (RMM) tools for Windows like ScreenConnect and AnyDesk.

Serious Vulnerability in the Internet Infrastructure Fundamental design flaw in DNSSEC discovered
he National Research Center for Applied Cybersecurity ATHENE has uncovered a critical flaw in the design of DNSSEC, the Security Extensions of DNS (Domain Name System). DNS is one of the fundamental building blocks of the Internet. The design flaw has devastating consequences for essentially all DNSSEC-validating DNS implementations and public DNS providers, such as Google and Cloudflare. The ATHENE team, led by Prof. Dr. Haya Schulmann from Goethe University Frankfurt, developed “KeyTrap”, a new class of attacks: with just a single DNS packet hackers could stall all widely used DNS implementations and public DNS providers. Exploitation of this attack would have severe consequences for any application using the Internet including unavailability of technologies such as web-browsing, e-mail, and instant messaging. With KeyTrap, an attacker could completely disable large parts of the worldwide Internet. The researchers worked with all relevant vendors and major public DNS providers over several months, resulting in a number of vendor-specific patches, the last ones published on Tuesday, February 13. It is highly recommended for all providers of DNS services to apply these patches immediately to mitigate this critical vulnerability.

PROPHET SPIDER Exploits Citrix ShareFile
At the start of 2022, CrowdStrike Intelligence and CrowdStrike Services investigated an incident in which PROPHET SPIDER exploited CVE-2021-22941 — a remote code execution (RCE) vulnerability impacting Citrix ShareFile Storage Zones Controller — to compromise a Microsoft Internet Information Services (IIS) web server. The adversary exploited the vulnerability to deploy a webshell that enabled the downloading of additional tools. This incident highlights how PROPHET SPIDER continues to evolve their tradecraft while continuing to exploit known web-server vulnerabilities.
The Dirty Pipe Vulnerability — The Dirty Pipe Vulnerability documentation
This is the story of CVE-2022-0847, a vulnerability in the Linux kernel since 5.8 which allows overwriting data in arbitrary read-only files. This leads to privilege escalation because unprivileged processes can inject code into root processes. It is similar to CVE-2016-5195 “Dirty Cow” but is easier to exploit. The vulnerability was fixed in Linux 5.16.11, 5.15.25 and 5.10.102.

Leaky Vessels flaws allow hackers to escape Docker, runc containers
Four vulnerabilities collectively called "Leaky Vessels" allow hackers to escape containers and access data on the underlying host operating system. The flaws were discovered by Snyk security researcher Rory McNamara in November 2023, who reported them to impacted parties for fixing. Snyk has found no signs of active exploitation of the Leaky Vessels flaws in the wild, but the publicity could change the exploitation status, so all impacted system admins are recommended to apply the available security updates as soon as possible.

smith (CVE-2023-32434)
This write-up presents an exploit for a vulnerability in the XNU kernel: Assigned CVE-2023-32434. Fixed in iOS 16.5.1 and macOS 13.4.1. Reachable from the WebContent sandbox and might have been actively exploited. *Note that this CVE fixed multiple integer overflows, so it is unclear whether or not the integer overflow used in my exploit was also used in-the-wild. Moreover, if it was, it might not have been exploited in the same way. The exploit has been successfully tested on: iOS 16.3, 16.3.1, 16.4 and 16.5 (iPhone 14 Pro Max) macOS 13.1 and 13.4 (MacBook Air M2 2022) All code snippets shown below are from xnu-8792.81.2.
