Unauthenticated, remote attackers can execute arbitrary OS commands with root privileges against certain Palo Alto’s GlobalProtect firewalls, using a just announced critical severity vulnerability which is being actively exploited in the wild. While limited to specific versions and configurations, unauthenticated remote command execution vulnerabilities are among the most severe security vulnerabilities that exist. Indeed, CVE-2024-3400 has a critical 10 out of 10 rating under CVSS.

A command injection vulnerability has been discovered in the GlobalProtect feature within Palo Alto Networks PAN-OS software for specific versions that have distinct feature configurations that may enable a remote, unauthenticated attacker to execute arbitrary code with root privileges on the firewall. These specific versions require configurations for GlobalProtect gateway and device telemetry enabled.

CrowdStrike is constantly working to protect our customers from the newest and most advanced cybersecurity threats. We are actively monitoring activity related to CVE-2024-3400, a critical command injection vulnerability in the GlobalProtect feature of Palo Alto Networks’ PAN-OS software affecting “specific PAN-OS versions and distinct feature configurations,” the vendor says.

If you spend quite a bit of time in the command line, working with Docker images and containers locally to build and test them, you might be in the mood for some power-user Docker commands. We're skipping the basics and diving straight into the lesser-known yet highly effective commands that can significantly improve your Docker experience.

In a new threat briefing, Forescout Research – Vedere Labs details an exploitation campaign targeting organizations running Fortinet’s FortiClient EMS which is vulnerable to CVE-2023-48788. We are designating this campaign Connect:fun because of the use of ScreenConnect and Powerfun as post-exploitation tools – our first-ever named campaign.

Before we start this blog post, let’s acknowledge that the only way to secure your environment from any vulnerability is to update the vulnerable hardware or software with patches that the author or the project community releases. Every other form of mitigation is only a way to provide an extended time for critical applications that cannot be updated immediately.
