Researchers Disclose Critical RCE Vulnerability Affecting Quarkus Java Framework

Researchers Disclose Critical RCE Vulnerability Affecting Quarkus Java Framework

Dec 01, 2022 Kubernetes / Vulnerability Management
A critical security vulnerability has been disclosed in the Quarkus Java framework that could be potentially exploited to achieve remote code execution on affected systems. Tracked as  CVE-2022-4116  (CVSS score: 9.8), the shortcoming could be trivially abused by a malicious actor without any privileges. "The vulnerability is found in the Dev UI Config Editor, which is vulnerable to drive-by localhost attacks that could lead to remote-code execution (RCE)," Contrast Security researcher Joseph Beeton, who reported the bug,  said  in a write-up. Quarkus, developed by Red Hat, is an  open source project  that's used for creating Java applications in  containerized  and serverless environments. It's worth pointing out that the  issue  only impacts developers who are running Quarkus and are tricked into visiting a specially crafted website, which is embedded with malicious JavaScript code designed to install or execute arbitrary payloads. This could take the form o

Moving Forward After CentOS 8 EOL

Sep 10, 2021
The Linux community was caught unprepared when, in December 2020, as part of a change in the way Red Hat supports and develops CentOS, Red Hat suddenly announced that it's cutting the official CentOS 8 support window from ten years – to just two, with support ending Dec 31, 2021. It created a peculiar situation where CentOS 7 users that did the right thing and upgraded quickly to CentOS 8 were left using an OS with just a year's official support remaining – while users of CentOS 7 still get full support until June 30, 2024. Worse, the fact that stable releases of CentOS were discontinued in exchange for the rolling-release CentOS Stream means that to secure their workloads most CentOS 8 users have to opt for an entirely different Linux distribution, with just a year to choose, evaluate and implement an alternative. Red Hat's unexpected decision underlined to what degree software users depend on official support windows for their software security. Countless organization
How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

Mar 21, 2024SaaS Security / Endpoint Security
In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must shorte
Warning! Unprivileged Linux Users With UID > INT_MAX Can Execute Any Command

Warning! Unprivileged Linux Users With UID > INT_MAX Can Execute Any Command

Dec 06, 2018
Hold tight, this may blow your mind… A low-privileged user account on most Linux operating systems with UID value anything greater than 2147483647 can execute any systemctl command unauthorizedly—thanks to a newly discovered vulnerability. The reported vulnerability actually resides in PolicyKit (also known as polkit)—an application-level toolkit for Unix-like operating systems that defines policies, handles system-wide privileges and provides a way for non-privileged processes to communicate with privileged ones, such as "sudo," that does not grant root permission to an entire process. The issue, tracked as CVE-2018-19788 , impacts PolicyKit version 0.115 which comes pre-installed on most popular Linux distributions, including Red Hat , Debian ,  Ubuntu , and CentOS. The vulnerability exists due to PolicyKit's improper validation of permission requests for any low-privileged user with UID greater than INT_MAX. Where, INT_MAX is a constant in computer progra

IBM Buys "Red Hat" Open-Source Software Company for $34 Billion

IBM Buys "Red Hat" Open-Source Software Company for $34 Billion

Oct 29, 2018
It's been quite a year for the open source platforms. Earlier this year, Microsoft acquired popular code repository hosting service GitHub for $7.5 billion , and now IBM has just announced the biggest open-source business deal ever. IBM today confirmed that it would be acquiring open source Linux firm Red Hat for $190 per share in cash, working out to a total value of approximately $34 billion. Red Hat, known for its Red Hat Enterprise Linux (RHEL) operating system, is a leading software company that offers open-source software products to the enterprise community. Even Oracle uses Red Hat's source code for its Oracle Linux product. Red Hat's last year revenue was $2.4 billion, and this year the company has earned $2.9 billion. But if Red Hat products are open source and updates are free, you might be wondering how does the company earn. Red Hat was one of the first companies who found a successful way to make money from free open-source software. It offers consul
New Privilege Escalation Flaw Affects Most Linux Distributions

New Privilege Escalation Flaw Affects Most Linux Distributions

Oct 26, 2018
An Indian security researcher has discovered a highly critical flaw in X.Org Server package that impacts OpenBSD and most Linux distributions, including Debian, Ubuntu, CentOS, Red Hat, and Fedora. Xorg X server is a popular open-source implementation of the X11 system (display server) that offers a graphical environment to a wider range of hardware and OS platforms. It serves as an intermediary between client and user applications to manage graphical displays. According to a blog post published by software security engineer Narendra Shinde , Xorg X server doesn't correctly handle and validate arguments for at least two command-line parameters, allowing a low-privileged user to execute malicious code and overwrite any file—including files owned by privileged users like root. The flaw, tracked as CVE-2018-14665 , was introduced in X.Org server 1.19.0 package that remained undetected for almost two years and could have been exploited by a local attacker on the terminal or vi
New Linux Kernel Bug Affects Red Hat, CentOS, and Debian Distributions

New Linux Kernel Bug Affects Red Hat, CentOS, and Debian Distributions

Sep 26, 2018
Security researchers have published the details and proof-of-concept (PoC) exploits of an integer overflow vulnerability in the Linux kernel that could allow an unprivileged user to gain superuser access to the targeted system. The vulnerability, discovered by cloud-based security and compliance solutions provider Qualys, which has been dubbed "Mutagen Astronomy," affects the kernel versions released between July 2007 and July 2017, impacting the Red Hat Enterprise Linux, CentOS, and Debian distributions. The Mutagen Astronomy vulnerability tracked as CVE-2018-14634, is a type of a local privilege escalation issue—one of the most common issues with operating systems as a whole—and exists in the Linux kernel's create_elf_tables() function that operates the memory tables. To successfully exploit this vulnerability, attackers need to have access to the targeted system and run their exploit that leads to a buffer overflow, thereby resulting in the execution of malici
Red Hat patches multiple web application Vulnerabilities

Red Hat patches multiple web application Vulnerabilities

Jan 04, 2013
RED HAT has fixed multiple web application security issues that allowed hackers to extract website database using Blind SQL injection. Red Hat also confirmed a cross site scripting and Local File Inclusion Vulnerabilities on their website. Mohamed Ramadan Security Researcher and Trainer Attack-Secure , told ' The Hacker News ' that last year he reported 3 flaws to the company and they finally confirm and patch those in January 2013. Blind SQL injection is identical to normal SQL Injection except that when an attacker attempts to exploit an application, rather than getting a useful error message, they get a generic page specified by the developer instead. This makes exploiting a potential SQL Injection attack more difficult but not impossible. Local file inclusion is a vulnerability that allows the attacker to read files, that are stored locally through the web application.This happens because the code of the application does not properly sanitize the include
