Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Memory corruption in PAN-OS 7.1.24 and earlier, PAN-OS 8.0.19 and earlier, PAN-OS 8.1.9 and earlier, and PAN-OS 9.0.3 and earlier will allow a remote, unauthenticated user to craft a message to Secure Shell Daemon (SSHD) and corrupt arbitrary memory.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Memory corruption vulnerability in PAN-OS Secure Shell Daemon (SSHD) affecting versions 7.1.24 and earlier, 8.0.19 and earlier, 8.1.9 and earlier, and 9.0.3 and earlier. A remote, unauthenticated attacker can send specially crafted messages to corrupt arbitrary memory, potentially leading to code execution.

MitigationUpgrade PAN-OS to a version newer than the affected versions (7.1.25+, 8.0.20+, 8.1.10+, or 9.0.4+) to patch the memory corruption vulnerability in SSHD.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify PAN-OS version
    Run 'show system info' from the PAN-OS CLI or check the System Information page in the web management interface
    Affected if The installed version is 7.1.24 or earlier, 8.0.19 or earlier, 8.1.9 or earlier, or 9.0.3 or earlier
  2. Confirm SSH daemon is enabled
    Run 'show system services' from the CLI or check the Device > Setup > Management > Management Interface Settings in the web UI to verify SSH service is enabled
    Affected if SSH (SSHD) is enabled on any interface (management or data plane)
  3. Check SSH access from untrusted networks
    Review the interface bindings and security zone assignments for SSH access. Use 'show interface' and check which zones the management or data plane interfaces with SSH are assigned to
    Affected if SSH is accessible from untrusted zones, external interfaces, or the internet (not just from trusted management networks)

A user is affected if their PAN-OS version falls within the vulnerable ranges AND SSH daemon is enabled and accessible from a network where unauthenticated attackers could reach it.

Upgrade available Upgrade to a release after 9.0.3
Interim mitigation

Upgrade PAN-OS to a version newer than the affected versions (7.1.25+, 8.0.20+, 8.1.10+, or 9.0.4+) to patch the memory corruption vulnerability in SSHD.

Recommended fix High confidence

PAN-OS 7.1.25+ (or migrate to 8.1+), 8.0.20+, 8.1.10+, or 9.0.4+ (recommended: latest 9.1.x or 10.x for longest support)

  1. 1. Identify the current PAN-OS version by navigating to Device > Summary in the web interface or running 'show system info' in CLI
  2. 2. Determine which branch (7.1, 8.0, 8.1, or 9.0) is currently running
  3. 3. For PAN-OS 7.1.x: Upgrade to PAN-OS 7.1.25 or later (note: 7.1 branch may be end-of-life; consider migrating to a supported branch)
  4. 4. For PAN-OS 8.0.x: Upgrade to PAN-OS 8.0.20 or later
  5. 5. For PAN-OS 8.1.x: Upgrade to PAN-OS 8.1.10 or later
  6. 6. For PAN-OS 9.0.x: Upgrade to PAN-OS 9.0.4 or later
  7. 7. Download the appropriate PAN-OS update from Palo Alto Networks support portal
  8. 8. Upload and install the update via Device > Software or via CLI with 'request system software install'
Caveat Upgrading PAN-OS may introduce behavioral changes; test thoroughly in non-production environment first. The 7.1 branch is end-of-life; consider migrating to a supported branch (8.1+, 9.0+, or 10.x) for continued security updates.
