Azure Serial Console Attack and Defense - Part 1

Ever had a virtual machine crash? Azure Serial console is a great way to directly connect to your Virtual machine and debug what went wrong. Azure Serial Console is a feature that’s available for free for everyone. While the primary intent of this feature is to assist users debug their machine, there are several interesting ways to abuse the features and compromise sensitive information.

Persistent volume support with peer-pods: Solution overview

Peer-pods, also known as the Kata remote hypervisor, enable the creation of Kata Virtual Machines (VM) on any environment, be it on-prem or in the cloud, without requiring bare metal servers or nested virtualization support. This is accomplished by extending Kata containers runtime to manage the VM lifecycle using cloud provider APIs (e.g., AWS, Azure) or third-party hypervisor APIs (such as VMware vSphere). Since peer-pods are separate VMs alongside the Kubernetes node, traditional Container Storage Interface (CSI) cannot function properly within them, and different solutions are required.

CVE-2023-36673: Widespread design flaws in VPN clients

An issue was discovered in Avira Phantom VPN through 2.23.1 for macOS. The VPN client insecurely configures the operating system such that all IP traffic to the VPN server's IP address is sent in plaintext outside the VPN tunnel, even if this traffic is not generated by the VPN client, while simultaneously using plaintext DNS to look up the VPN server's IP address. This allows an adversary to trick the victim into sending traffic to arbitrary IP addresses in plaintext outside the VPN tunnel. NOTE: the tunnelcrack.mathyvanhoef.com website uses this CVE ID to refer more generally to "ServerIP attack, combined with DNS spoofing, that can leak traffic to an arbitrary IP address" rather than to only Avira Phantom VPN.

Metabase Remote Code Execution

Metabase versions before 0.46.6.1 contain a flaw where the secret setup-token is accessible even after the setup process has been completed. With this token a user is able to submit the setup functionality to create a new database. When creating a new database, an H2 database string is created with a TRIGGER that allows for code execution. We use a sample database for our connection string to prevent corrupting real databases. Successfully tested against Metabase 0.46.6.

Ubuntu Security Notice USN-6278-1

Ubuntu Security Notice 6278-1 - It was discovered that .NET did not properly handle the execution of certain commands. An attacker could possibly use this issue to achieve remote code execution. Benoit Foucher discovered that .NET did not properly implement the QUIC stream limit in HTTP/3. An attacker could possibly use this issue to cause a denial of service. It was discovered that .NET did not properly handle the disconnection of potentially malicious clients interfacing with a Kestrel server. An attacker could possibly use this issue to cause a denial of service.

Collide+Power, Downfall, and Inception: New Side-Channel Attacks Affecting Modern CPUs

Cybersecurity researchers have disclosed details of a trio of side-channel attacks that could be exploited to leak sensitive data from modern CPUs. Called Collide+Power (CVE-2023-20583), Downfall (CVE-2022-40982), and Inception (CVE-2023-20569), the novel methods follow the disclosure of another newly discovered security vulnerability affecting AMD's Zen 2 architecture-based processors known as

GHSA-5824-cm3x-3c38: Vyper has incorrectly allocated named re-entrancy locks

### Impact In versions 0.2.15, 0.2.16 and 0.3.0, named re-entrancy locks are allocated incorrectly. Each function using a named re-entrancy lock gets a unique lock regardless of the key, allowing cross-function re-entrancy in contracts compiled with the susceptible versions. A specific set of conditions is required to result in misbehavior of affected contracts, specifically: - A `.vy` contract compiled with either of the following `vyper` versions: `0.2.15`, `0.2.16`, `0.3.0` - A primary function that utilizes the `@nonreentrant` decorator with a specific `key` and does not strictly follow the check-effects-interaction pattern (i.e. contains an external call to an untrusted party before storage updates) - A secondary function that utilizes the same `key` and would be affected by the improper state caused by the primary function ### Patches https://github.com/vyperlang/vyper/pull/2439, https://github.com/vyperlang/vyper/pull/2514 ### Workarounds Upgrade to 0.3.1 or higher ### Refe...

CVE-2023-4243: FULL - Customer <= 2.2.3 - Authenticated(Subscriber+) Improper Authorization to Arbitrary Plugin Installation — Wordfence Intelligence

The FULL - Customer plugin for WordPress is vulnerable to Arbitrary File Upload via the /install-plugin REST route in versions up to, and including, 2.2.3 due to improper authorization. This allows authenticated attackers with subscriber-level permissions and above to execute code by installing plugins from arbitrary remote locations including non-repository sources onto the site, granted they are packaged as a valid WordPress plugin.

CVE-2023-4242: FULL - Customer <= 2.2.3 - Authenticated(Subscriber+) Information Disclosure via Health Check — Wordfence Intelligence

The FULL - Customer plugin for WordPress is vulnerable to Information Disclosure via the /health REST route in versions up to, and including, 2.2.3 due to improper authorization. This allows authenticated attackers with subscriber-level permissions and above to obtain sensitive information about the site configuration as disclosed by the WordPress health check.
