Easily remediate the CVEs most likely to harm you using Forward Enhanced Device Vulnerability Analysis

Headline grabbing vulnerabilities, like SolarWinds and Log4Shell, target management software and end hosts, but if you search for “most exploited vulnerabilities” on Google, you will quickly learn that some of them directly target network and security devices as well as server load balancers. These are the 3 most exploited CVEs in the last couple of years: Would you be surprised to learn that network device operating systems can be vulnerable to security flaws like any other software?

Announcing customized role-based access controls for Snyk

As your development and security teams grow, it becomes critical that each of your team members using Snyk has only the required permissions to do their job. You need to ensure everyone can perform their jobs with ease, while also avoiding security and compliance issues. A developer, for example, needs the ability to find and fix vulnerabilities in his code but should not be able to change Snyk billing details.

CVE-2022-30522 - Denial of Service (DoS) Vulnerability in Apache httpd "mod_sed" filter

This past March we posted an analysis of a vulnerability in the Apache HTTP Server mod_sed filter module, CVE-2022-23943, in which a Denial of Service (DoS) can be triggered due to a miscalculation of buffers’ sizes. While analyzing this Apache httpd vulnerability and its patch, we suspected that although the fix resolved the issue, it created a new unwanted behavior. Our suspicion turned out to be true: we discovered that another way to cause a DoS was introduced.

The Call Is Coming from Inside the House: CrowdStrike Identifies Novel Exploit in VOIP Appliance

CrowdStrike Services recently investigated a suspected ransomware intrusion attempt. The intrusion was quickly stopped through the customer’s efforts and those of the CrowdStrike Falcon Complete™ managed detection and response (MDR) team, which was supporting this customer’s environment.

Developer empowerment for software security with Snyk IDE plugins

For application security, the shift left strategy is something that every enterprise is embracing today, which essentially means putting the security controls in earlier stages of development. This is more like a “nipping the problem in the bud” strategy where the security controls in their respective domains highlight the potential security weaknesses related to vulnerabilities in code, vulnerabilities in third-party packages and code quality issues.

0-Days are on the Rise and that Means a Lot More Work for SOC Teams

In a recent report by the incident response giant Mandiant, which was purchased by Google in March, their researchers found that 2021 was a record year for the total number of 0-day vulnerabilities disclosed and exploited. According to their findings, their team identified some 80 0-days exploited in the wild. At the same time, Google Project Zero researchers reported the detection and disclosure of 58 0-days.

OT:ICEFALL: 56 Vulnerabilities Caused by Insecure-by-Design Practices in OT

It has been 10 years since Project Basecamp, a research project conducted by Digital Bond that investigated how critical operational technology (OT) devices and protocols were, to use the term they coined, “insecure by design.” Since then, we have seen hugely impactful real-world OT malware such as Industroyer, TRITON, Industroyer2 and INCONTROLLER abusing insecure-by-design functionality.

How to decide what to fix when you can't fix everything

Contributing to a legacy software development project, as a security-aware developer, is a bit like inheriting an old house. In my old house, the roof is missing tiles, the bathroom taps are dripping, the front door doesn't lock properly, the hallway needs redecorating and there are worrying cracks in the foundations. I don't know where to start. The security problems with the application I've recently (hypothetically) joined are similarly vexing and diverse. It has deprecated dependencies to older versions of software libraries. It could be misconfigured using insecure protocols.

The Importance of White-Box Testing: A Dive into CVE-2022-21662

I want to take some time to explain the importance of using a white-box approach when testing applications for vulnerabilities. To help in this endeavor, I will use a real-world example to demonstrate how researchers (in this case Karim El Ouerghemmi and Simon Scannell) *may* have found a vulnerability in WordPress (CVE-2022-21662 a 2nd order stored XSS) and how you, as a security researcher, can also use a white-box approach to find an exotic XSS vulnerability.

The Most Commonly Mixed-Up Security Terms: Learn the Differences Between Asset, Threat, Vulnerability, and Risk

The cybersecurity landscape is complex enough without the lack of a common vocabulary. But, often, organizations use common security terms incorrectly or interchangeably. This leads to confusion, which leads to frustration, which can lead to something much, much worse. Something like a breach. Let’s take a moment, then, to review the four most commonly mixed-up and misused security terms in the cybersecurity world.

A Weaponized npm Package '@core-pas/cyb-core' Proclaimed Pentesting Related

Two packages of well-known origin were found exfiltrating Windows SAM and SYSTEM files, apparently as part of internal security research rather than a targeted dependency confusion attack. On June 6th, 2022, the Mend research team used Supply Chain Defender to detect and flag two malicious packages from the same author that contained identical code. We alerted npm and the packages were removed within three hours of publication.

CVE-2022-25845 - Analyzing the Fastjson "Auto Type Bypass" RCE vulnerability

A few weeks ago, a new version for Fastjson was released (1.2.83) which contains a fix for a security vulnerability that allegedly allows an attacker to execute code on a remote machine. According to several publications, this vulnerability allows an attacker to bypass the “AutoTypeCheck” mechanism in Fastjson and achieve remote code execution. This Fastjson vulnerability only recently received a CVE identifier – CVE-2022-25845, and a high CVSS – 8.1.

How ADAudit Plus helps you assess your exposure to Follina (CVE-2022-30190)

The recently discovered Windows zero-day vulnerability continues to make news as threat actors across the globe are relentless in their efforts to exploit it.

What is a Dependency Firewall? What, Why and How?

In recent years more open source vulnerabilities have been discovered than ever before. This is all part of the natural evolution; it’s what we expect to see as the amount of open source usage grows within organizations. But there’s something that we missed in this equation: while identifying vulnerabilities, organizations haven’t found a way to block unwanted dependencies, which made them vulnerable to attacks like never before.

Trustwave's Action Response: More MSDT Fallout with "Dogwalk"
