Ubuntu Security Notice 7051-1 - Fabian Bäumer, Marcus Brinkmann, Joerg Schwenk discovered that the SSH protocol was vulnerable to a prefix truncation attack. If a remote attacker was able to intercept SSH communications, extension negotiation messages could be truncated, possibly leading to certain algorithms and features being downgraded. This issue is known as the Terrapin attack. This update adds protocol extensions to mitigate this issue.
Cybersecurity researchers have uncovered a new cryptojacking campaign targeting the Docker Engine API with the goal of co-opting the instances to join a malicious Docker Swarm controlled by the threat actor. This enabled the attackers to "use Docker Swarm's orchestration features for command-and-control (C2) purposes," Datadog researchers Matt Muir and Andy Giron said in an analysis. The attacks
Vault’s SSH secrets engine did not require the valid_principals list to contain a value by default. If the valid_principals and default_user fields of the SSH secrets engine configuration are not set, an SSH certificate requested by an authorized user to Vault’s SSH secrets engine could be used to authenticate as any user on the host. Fixed in Vault Community Edition 1.17.6, and in Vault Enterprise 1.17.6, 1.16.10, and 1.15.15.
A researcher claims to have found a decade-old vulnerability rated 9.9 that affects all GNU/Linux systems, allowing attackers…
This is a Linux/portable port of OpenBSD's excellent OpenSSH. OpenSSH is based on the last free version of Tatu Ylonen's SSH with all patent-encumbered algorithms removed, all known security bugs fixed, new features reintroduced, and many other clean-ups.
In IT environments, some secrets are managed well and some fly under the radar. Here’s a quick checklist of what kinds of secrets companies typically manage, including one type they should manage: Passwords [x] TLS certificates [x] Accounts [x] SSH keys ??? The secrets listed above are typically secured with privileged access management (PAM) solutions or similar. Yet, most traditional PAM
Hi, Rspack|Webpack developer team! ## Summary We discovered a DOM Clobbering vulnerability in Webpack’s AutoPublicPathRuntimeModule. The DOM Clobbering gadget in the module can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., an img tag with an unsanitized name attribute) are present. We found the real-world exploitation of this gadget in the Canvas LMS which allows XSS attack happens through an javascript code compiled by Webpack (the vulnerable part is from Webpack). We believe this is a severe issue. If Webpack’s code is not resilient to DOM Clobbering attacks, it could lead to significant security vulnerabilities in any web application using Webpack-compiled code. ## Details ### Backgrounds DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code) living in t...
The cryptojacking operation known as TeamTNT has likely resurfaced as part of a new campaign targeting Virtual Private Server (VPS) infrastructures based on the CentOS operating system. "The initial access was accomplished via a Secure Shell (SSH) brute force attack on the victim's assets, during which the threat actor uploaded a malicious script," Group-IB researchers Vito Alfano and Nam Le
In a previous post-quantum (PQ) article, we introduced the threat that quantum computing presents for any systems, networks and applications that utilize cryptography. In this article, you’ll learn what you can do to assist your organization in achieving crypto-agility with Red Hat and what to expect of Red Hat products as we begin to integrate post-quantum cryptographic functions into them.The capabilities described in the following sections assume timely and functional implementation of industry standards and specifications and the libraries that implement them. If these are not achieved,
Cybersecurity researchers have uncovered a new malware campaign targeting Linux environments to conduct illicit cryptocurrency mining. The activity, which specifically singles out the Oracle Weblogic server, is designed to deliver malware dubbed Hadooken, according to cloud security firm Aqua. "When Hadooken is executed, it drops a Tsunami malware and deploys a crypto miner," security researcher
