CVE-2024-3385 — A packet processing mechanism in Palo Alto Networks PAN-OS software enables a remote attacker to reboot hardware-based firewalls

High CVSS 7.5

A packet processing mechanism in Palo Alto Networks PAN-OS software enables a remote attacker to reboot hardware-based firewalls. Repeated attacks eventually cause the firewall to enter maintenance mode, which requires manual intervention to bring the firewall back online. This affects the following hardware firewall models: - PA-5400 Series firewalls - PA-7000 Series firewalls

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
