Workplaces have evolved. While hybrid and remote work existed before COVID-19, these working arrangements became even more prevalent during and after the pandemic. Today, workplaces offer the flexibility for employees to work and access company resources from anywhere worldwide, with the Server Message Block (SMB) protocol at the center of this.

Mailcow Mail Server Vulnerabilities Expose Servers to Remote Code Execution Recently, two significant security vulnerabilities have been uncovered in the Mailcow open-source mail server suite. These vulnerabilities, which affect all versions prior to 2024-04, were disclosed by SonarSource on March 22, 2024, and could allow malicious actors to execute arbitrary code on vulnerable Mailcow instances. Understanding the Vulnerabilities.

What are your most important corporate assets? Like most companies, you probably have mission-critical assets and those that play a smaller role in your revenue and continuity. You are also likely to be using Vulnerability Management or Assessment tools to lock down where those assets can potentially be compromised. Vulnerability Prioritization combines asset importance and potential for risk.

On June 17, 2024, VMware disclosed two critical vulnerabilities (CVE-2024-37079 & CVE-2024-37080) affecting vCenter Server and Cloud Foundation. These vulnerabilities stem from a heap-overflow issue in the implementation of the DCERPC protocol which can be exploited by remote threat actors. By sending specially crafted network packets, threat actors could exploit CVE-2024-37079 and CVE-2024-37080 to achieve Remote Code Execution (RCE) on both vCenter Server and Cloud Foundation systems.

In 2016, the Large Hadron Collider in Switzerland fell prey to a vicious and devastating attack.

Communication across business units, technology layers, and systems is a massive challenge when it comes to streamlining any process, especially vulnerability remediation. Seemplicity’s new Microsoft Teams integration elevates cross team collaboration by facilitating the distribution of information, remediation requests, and more. These capabilities enable users to share findings with varying levels of context, depending on the recipients’ requirements. .

ASUS recently issued a firmware update to resolve a critical security vulnerability affecting seven different variants of its router models.

Knowing what you don’t know is the key to keeping an organization safe and the best method of doing so is with an offensive security approach that includes vulnerability scanning. By being proactive one can identify exploitable weaknesses in your own systems before malicious actors can. Here's why vulnerability scanning is an essential part of any offensive security solution: Vulnerability scanning is just one piece of the offensive security puzzle, but it's a crucial one.

As I mentioned at the beginning of this year, I am trying to do a monthly blog post on what might be termed “Major Security Events”. In particular this year, I’ve written about the Ivanti meltdown, Lockbit ransomware, and the xz backdoor. These events usually emerge cacophonously and suddenly into the cybersecurity landscape, and generally get everyone’s attention “real quick”.

After our recent successes exploring WebSocket Hijacking vulnerabilities, we decided to expand this research project into other attacks that involve WebSockets. We started by looking at WebSocket smuggling attacks and expanded our scope to include HTTP response header injection attacks and potential novel impacts.
