  • Got a cheap Cisco router in your home office? If it's one of these, there's an exposed RCE hole you need to plug

    Cisco has published patches for critical vulns affecting the web management interface for some of its Small Business Dual WAN Gigabit routers – including a 9.8-rated nasty.

    The two vulnerabilities affect the RV340, RV345, RV340W, and RV345P products, which are aimed at SMEs and home office setups. Attackers abusing them on unpatched devices are able to execute arbitrary code and also force reboots of affected routers, causing a denial-of-service condition.

    CVE-2021-1609, rated 9.8 on the CVSS v3.1 scale, allows attackers to "remotely execute arbitrary code" thanks to improper validation of HTTP requests, according to Cisco's advisory.

    Similarly, CVE-2021-1610 (advisory also available at the link above) is a command injection vuln allowing attackers to run arbitrary commands as root – again, because "HTTP requests are not properly validated." This one's rated at 7.2 on the CVSS v3.1 scale.

  • Google Play puts Android apps on notice: No naughty JavaScript, Python, Lua

    Google's pending Play Store policy changes are bringing various privacy improvements – but also include a security enhancement and disclosure requirement that deserve mention.

    First, there's a specific ban on the deceptive use of interpreted languages like JavaScript, Python, and Lua. This is more of a refinement and tightening of prior policy than a new rule.

    Starting October 15, 2021, Google said, "We're clarifying the Device and Network Abuse policy to prohibit apps or SDKs with interpreted languages (e.g., JavaScript) loaded at run time from violating any Google Play policies."

  • Das tut mir leid! Germany's ruling party sorry for calling cops on researcher after she outed canvassing app flaws

    A "left-wing" German infosec researcher was this week threatened with criminal prosecution after revealing that an app used by Angela Merkel's political party to canvass voters was secretly collecting personal data.

    Germany's respected Chaos Computer Club (CCC) announced it would stop reporting any weaknesses in the centre-right wing Christian Democratic Union's (CDU) web-facing infrastructure to the party after it procured a criminal prosecution against Lilith Wittmann.

    "I got an email from the Cyber Security Police of Berlin," she told The Register. "Could you please provide us your address, so we can send you... legal documents? And then I was like, that's weird. I didn't do anything wrong. Let's tweet about that. Let's find a lawyer who can look into that."

    Although the prosecution is due to be withdrawn after an apology from the CDU, the episode shines a light on some German politicians' attitudes to vulnerability disclosures.

  • Credit-card-stealing, backdoored packages found in Python's PyPI library hub

    Malicious libraries capable of lifting credit card numbers and opening backdoors on infected machines have been found in PyPI, the official third-party software repository for Python.

    That's according to the JFrog security research team, which documented its findings here at the end of last month.

  • We can't believe people use browsers to manage their passwords, says maker of password management tools

    It seems some of us are, in the year of our lord 2021, still reusing the same password for multiple sites, plugging personal gear into work networks, and perhaps overly relying on browser-managed passwords, judging from this poll.

    ThycoticCentrify, formed from a merger between two computer access management firms, said it surveyed about 8,000 people, and reports just under a quarter admitted they reuse passwords across multiple websites – a cybersecurity no-no because it opens you up to credential stuffing.

  • Josh Bressers: Episode 283 – When vulnerability disclosure becomes dangerous

    Josh and Kurt talk about a very difficult disclosure problem. What happens when you have to report a vulnerability to an ethically questionable company? It’s less simple than it sounds, many of the choices could end up harming victims.

  • Ordinary salaried Brits: Sweet! Payday! Banking giant HSBC: Oh no it isn't • The Register

    According to Downdetector, users started reported problems between 8 and 9am BST this morning just as many were starting their day's work.

    It's not clear at this stage what's behind the outage, prompting some to criticise the lack of information from HSBC.

    HSBC's status page suggests that the bank's systems are all functioning well. But that doesn't chime with what some customers are experiencing.

  • 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.
