CVE-2024-3382: PAN-OS: Firewall Denial of Service (DoS) via a Burst of Crafted Packets

A memory leak exists in Palo Alto Networks PAN-OS software that enables an attacker to send a burst of crafted packets through the firewall that eventually prevents the firewall from processing traffic. This issue applies only to PA-5400 Series devices that are running PAN-OS software with the SSL Forward Proxy feature enabled.

Security readout for executives and security teams

Plain-English summary

This issue can let an unauthenticated network attacker disrupt an affected Palo Alto firewall by causing a memory leak with crafted traffic. The result is availability loss: the firewall can eventually stop processing traffic. The source bundle limits impact to PA-5400 Series devices running PAN-OS with SSL Forward Proxy enabled.

Executive priority

Treat as high priority where PA-5400 firewalls inspect critical traffic with SSL Forward Proxy enabled. The business risk is outage or degraded network security enforcement, not data theft. Scope first, then follow vendor remediation guidance.

Technical view

CVE-2024-3382 is a PAN-OS memory leak categorized as CWE-770. CVSS 3.1 is 7.5, driven by network reachability, low complexity, no privileges, no user interaction, and high availability impact. Cloud NGFW and Prisma Access are listed as unaffected in the provided source bundle.

Likely exposure

Exposure appears narrow: PA-5400 Series appliances running PAN-OS version families listed in the bundle and using SSL Forward Proxy. Internet-edge, data-center, or egress inspection deployments would carry the most operational risk if traffic disruption would affect critical services.

Exploitation context

The bundle does not show CISA KEV status and provides no evidence of active exploitation. The attack scenario is denial of service, not confidentiality or integrity compromise. The attacker must send crafted packets through the firewall path where the vulnerable feature is active.

Researcher notes

Evidence is limited to the supplied CVE and vendor reference. Do not assume broader PAN-OS platform impact beyond the stated PA-5400 and SSL Forward Proxy condition. No public exploit activity is supported by the bundle.

Mitigation direction

  • Inventory PA-5400 Series firewalls and PAN-OS versions.
  • Confirm whether SSL Forward Proxy is enabled on each device.
  • Review Palo Alto Networks guidance for fixed releases or supported mitigations.
  • Prioritize remediation for firewalls protecting critical traffic paths.
  • Monitor memory pressure and traffic-processing health until remediated.

Validation and detection

  • Check asset inventory for PA-5400 Series devices.
  • Verify PAN-OS versions against the vendor advisory.
  • Confirm SSL Forward Proxy configuration status.
  • Review logs and telemetry for repeated memory growth or traffic-processing failures.
  • Document Cloud NGFW and Prisma Access as unaffected if applicable.
