What is CVE-2024-3400?

CVE-2024-3400 is PAN-OS: Arbitrary File Creation Leads to OS Command Injection Vulnerability in GlobalProtect. The supplied enrichment data classifies it as Remote Code Exec mapped to CWE-77 Command Injection; CWE-20 Improper Input Validation.

Which versions are affected?

Affected product and version evidence is listed in the product table above. Current public advisories should be checked for exact version scope before patch targeting is finalized.

Is there active exploitation?

Yes: CISA KEV signal present. If exploitation is not confirmed from current sources, teams should document that status and continue monitoring KEV, vendor, and telemetry updates.

Is there a public exploit?

317 public PoC repositories reported; 1 marked weaponized in current dataset. Public exploit or PoC availability should raise triage priority, especially for exposed or business-critical systems.

How can defenders detect it?

Start with web/proxy/WAF logs, application logs, network IDS/IPS, EDR process telemetry, host service logs where available. Look for vulnerability-class behavior, product errors, suspicious authentication events, exploit probes, and abnormal process activity based only on evidence that applies to the affected product.

How should teams prioritize it?

Prioritize CVE-2024-3400 using CVSS 10, EPSS 100%, KEV status, public PoC status, and asset exposure. Internet-facing, privileged, or business-critical deployments should be handled first.

Are workarounds available?

Workarounds are not confirmed from current sources. Fixed-version evidence is listed in the mitigation section above.

Which threat actors are linked publicly?

Publicly linked actor or ransomware signals in the supplied enrichment data: UTA0218 (), FIN7 (), BRONZE HIGHLAND (), APT 29 (), Fox Kitten (), Ransomware use: Known. Do not attribute exploitation to a threat actor unless the source evidence explicitly supports that linkage.

What should be done in the next 24 hours?

Identify exposed assets running affected vendor/product/version combinations. Treat as emergency remediation because CISA KEV status is present. Search available logs for exploit probes, errors, authentication anomalies, or suspicious child processes matching the vulnerability class. Open remediation tickets with affected assets, owners, evidence status, and detection coverage so decisions are traceable.

CVE-2024-3400 — PAN-OS: Arbitrary File Creation Leads to OS Command Injection Vulnerability in GlobalProtect

Q: Is it in CISA KEV?

Yes. The supplied enrichment data lists CVE-2024-3400 in CISA KEV with required action: 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.. KEV status should be monitored because it can change after initial disclosure or after exploitation becomes publicly confirmed.

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.

Remediation

The vendor's own words where we have them.

We strongly advise customers to immediately upgrade to a fixed version of PAN-OS to protect their devices even when workarounds and mitigations have been applied. This issue is fixed in PAN-OS 10.2.9-h1, PAN-OS 11.0.4-h1, PAN-OS 11.1.2-h3, and in all later PAN-OS versions. Customers who upgrade to these versions will be fully protected.

CISA required action

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.

What this weakness leads to

MITRE's own consequences and mitigations for the weakness class — the authority's wording, not guidance derived from the CVSS vector.

MITRE

CWE-20 · Improper Input Validation

DoS: Crash, Exit, or Restart
DoS: Resource Consumption (CPU)
DoS: Resource Consumption (Memory)
Read Memory

Mitigation: Consider using language-theoretic security (LangSec) techniques that characterize inputs using a formal language and build recognizers for that language. This effectively requires parsing to be a distinct layer that effectively enforces a boundary between raw input and internal data representations, instead of allowing parser code to be scattered throughout the program, where it could be subject to errors or inconsistencies that create weaknesses. [REF-1109] [REF-1110] [REF-1111]

CWE-77 · Improper Neutralization of Special Elements used in a Command ('Command Injection')

Execute Unauthorized Code or Commands

Mitigation: If at all possible, use library calls rather than external processes to recreate the desired functionality.

Answered from this record1

What should defenders know first?

CVE-2024-3400 is PAN-OS: Arbitrary File Creation Leads to OS Command Injection Vulnerability in GlobalProtect, a critical vulnerability affecting PAN-OS, Cloud NGFW, Prisma Access from Palo Alto Networks. The current evidence lists it in CISA KEV, and the exploit status is: Yes: CISA KEV signal present. Public exploit evidence is: 317 public PoC repositories reported; 1 marked weaponized in current dataset. The affected-version evidence is listed in the key facts and affected products tables. Defenders should first verify whether exposed or business-critical assets run those versions, then apply vendor patches or mitigations, restrict reachable attack surface, and preserve logs for detection review. CVSS 10 describes technical severity, while EPSS 100% helps estimate near-term exploit likelihood; neither replaces asset context. Unknown fields should remain explicit in tickets, and threat actor, IOC, victimology, or payload claims should not be added unless a cited source supports them. Monitor CISA KEV, vendor advisories, NVD changes, public PoC repositories, and internal telemetry for update triggers.
