Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2024-3400?

CVE-2024-3400 has an EPSS (Exploit Prediction Scoring System) score of 94.3%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2024-3400 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2024-3400 (Palo Alto Networks PAN-OS Command Injection Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2024-04-12. CISA required all US federal civilian agencies to remediate this vulnerability by 2024-04-19. The required action was: Apply mitigations per vendor instructions as they become available. Otherwise, users with vulnerable versions of affected devices should enable Threat Prevention IDs available from the vendor. See the vendor bulletin for more details and a patch release schedule. This CVE has been used in known ransomware campaigns. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

Q: Can O3 Security detect CVE-2024-3400 in my codebase?

Yes. O3 Security's Impact-Aware SCA scanner identifies CVE-2024-3400 across all affected ecosystems (multiple ecosystems), correlates it against your dependency graph, and uses function-level reachability to confirm whether the vulnerable code path is actually reachable in your application — eliminating false positives. You can scan your stack for CVE-2024-3400 directly from the O3 platform.

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

A command injection as a result of arbitrary file creation vulnerability in the GlobalProtect feature of Palo Alto Networks PAN-OS software for specific PAN-OS versions and distinct feature configurations may enable an unauthenticated attacker to execute arbitrary code with root privileges on the firewall.

Cloud NGFW, Panorama appliances, and Prisma Access are not impacted by this vulnerability.

Exploits & PoCs

Research use only. For defensive security, authorized penetration testing, and academic research only. Never execute exploit code against systems without explicit written authorization.
