— Ingenious AI security check.
Key figure: CISA's Known Exploited Vulnerabilities catalog listed 1,748 entries as of October 16, 2026, every one confirmed exploited in the wild (CISA KEV catalog, version 2026.10.16).
A firewall sits at the network’s edge with full trust — a vulnerability there bypasses every defense behind it. CVE-2026-0322 affects Palo Alto firewalls, the boxes guarding countless corporate networks. Check your PAN-OS version against the advisory immediately: edge devices get exploited within hours of disclosure.
An authenticated remote code execution flaw in the PAN-OS management interface lets an attacker with network access run code as root on your firewall. Palo Alto Networks confirmed very limited exploitation in the wild, CISA put it on the Known Exploited Vulnerabilities list on October 14, and federal agencies must remediate by October 17. This free CVE check tool tells you if you're at risk. No signup, nothing installed.
Check your PAN-OS version — in the web UI: Device → Software — or on the CLI:
show system info | match sw-version
Check whether your management interface is reachable from untrusted networks — the exploit needs network access to the management interface. In the web UI: Network → Interfaces → Management → check the Permitted IP Addresses list. Then check from outside:
nmap -p 443 <your-mgmt-ip>
Check for signs of past compromise — Palo Alto released three attacker IP addresses in its advisory. Hunt your authentication logs for logins from unknown or foreign IPs, especially any administrative logins outside change windows:
Monitor → Logs → System — filter for admin authentication events since early October. Look for logins at odd hours, new admin accounts, or configuration commits nobody on your team made.
This page checked one CVE. BreachHunter tracks attacker infrastructure and exposed management interfaces across your footprint — the exact attack surface this CVE lives on.
PAN-OS 10.2 before 10.2.18-h12, 11.1 before 11.1.16-h3, 11.2 before 11.2.16, 12.1 before 12.1.10-h2, and 12.2 before 12.2.4 on PA-Series and VM-Series firewalls and Panorama appliances. Cloud NGFW and Prisma Access are not affected.
Yes — the attacker needs valid credentials AND network access to the PAN-OS management interface. That is why it is rated high severity (CVSS 8.6) rather than critical. But once those two conditions hold, the attacker gets arbitrary code execution as root. An internet-exposed management interface collapses the second condition to just stolen credentials.
CISA added CVE-2026-0322 to its Known Exploited Vulnerabilities catalog on October 14, 2026, with a remediation deadline of October 17, 2026 for US federal civilian agencies. Palo Alto Networks confirmed very limited exploitation in the wild. Patch immediately and restrict management-interface access to trusted IPs or a jump box in the meantime.
A CVE checker is a free tool that tells you whether your software is affected by a published CVE — a publicly known cybersecurity vulnerability. It compares your version or configuration against the official advisory and gives you a patched, vulnerable, or unknown verdict in about 30 seconds.
Find your exact version number, then compare it against the vendor's security advisory or the NVD entry for the CVE. The fastest way is a CVE checker built for that product: paste your version and get an instant verdict against the published version tables.
You are affected when you run a vulnerable version and the vulnerable component is reachable or enabled — for example, open sign-ups, an exposed management port, or a vulnerable app installed. A CVE checker gives you the version verdict in seconds; the advisory's conditions tell you whether that verdict means real exposure.
