On April 12, 2024, Palo Alto Networks published a security advisory detailing an actively exploited maximum severity vulnerability (CVE-2024-3400, CVSS: 10.0) affecting the GlobalProtect feature of PAN-OS. This vulnerability affects PAN-OS 10.2, PAN-OS 11.0, and PAN-OS 11.1 firewalls when configurations for both GlobalProtect gateway and device telemetry are enabled. An unauthenticated remote threat actor can exploit this vulnerability to execute arbitrary code with root privileges on the firewall.

On April 14, 2024, Palo Alto Networks (PAN) released hotfixes to address the maximum severity (CVSS: 10) vulnerability, CVE-2024-3400, affecting the GlobalProtect Feature of PAN-OS. An unauthenticated remote threat actor can exploit this vulnerability to execute arbitrary code with root privileges on the firewall. Volexity identified CVE-2024-3400 as a zero-day vulnerability and found that the threat actor UTA0218 was implanting a custom Python backdoor on firewall devices.

On April 12th, Palo Alto Networks released a CVE advisory for CVE-2024-3400, a critical vulnerability identified in the GlobalProtect Gateway feature of PAN-OS, the operating system for Palo Alto Networks firewalls. This command injection vulnerability allows unauthenticated attackers to execute arbitrary commands with root privileges on the affected devices.

Recently, a critical vulnerability, CVE-2024-3400, was discovered in the Palo Alto Networks PAN-OS software, posing a substantial risk to affected systems. In this blog post, we will discuss the nature of this vulnerability and how Forward Networks can assist organizations in swiftly identifying and addressing their risk exposure.

The recent discovery of a backdoor in XZ Utils (CVE-2024-3094), a data compression utility used by a wide array of various open-source, Linux-based computer applications, underscores the importance of open-source software security. While it is often not consumer-facing, open-source software is a critical component of computing and internet functions, such as secure communications between machines.

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.
