  • New HP MFP vulnerabilities show why you should update and isolate printers | CSO Online

    Security researchers have published details about two serious vulnerabilities that impact over 150 different HP multifunction printer models with FutureSmart firmware going back at least nine years. The attack vectors associated with the flaws and their impact serve as a reminder that printers can pose significant security risks to enterprise networks if not properly secured, updated and segmented.

    "For one, the vulnerabilities date back to at least 2013 and affect a large number of HP products released," researchers from security firm F-Secure, who found the flaws, said in their report. "HP is a large company that sells products all over the world. Many companies are likely using these vulnerable devices. To make matters worse, many organizations don’t treat printers like other types of endpoints. That means IT and security teams forget about these devices’ basic security hygiene, such as installing updates."

    Exploiting one of the vulnerabilities requires physical access and can be done through physical ports that are exposed on its communications board. A skilled attacker with physical access to a vulnerable MFP would need around five minutes to perform the attack and deploy a stealthy implant that could take full control of the device and exfiltrate potentially sensitive information.

    The second vulnerability is even more dangerous because it's located in the firmware's font parsing code and essentially allows anyone who can print a specifically crafted file to execute malicious code on the vulnerable MFPs. The vulnerability is wormable and exploitation can be achieved in seconds through multiple remote attack vectors, including by users visiting malicious websites.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
