Which products are affected by CVE-2019-1579?

Affected package information for CVE-2019-1579 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2019-1579?

Apply the paloaltonetworks pan-os security patch or hotfix for CVE-2019-1579 on the affected version, following the vendor advisory for your exact build.

How do I detect CVE-2019-1579 across my infrastructure?

Inventory every paloaltonetworks pan-os deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2019-1579 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2019-1579?

O3 detects and blocks CVE-2019-1579 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2019-1579 actively exploited in the wild?

Yes. There are 6 known exploit references for CVE-2019-1579, including 5 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2019-1579?

CVE-2019-1579 has an EPSS (Exploit Prediction Scoring System) score of 39.3%, placing it in the 98th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score warrants monitoring and prompt remediation.

Is CVE-2019-1579 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2019-1579 (Palo Alto Networks PAN-OS Remote Code Execution Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2022-01-10. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-07-10. The required action was: Apply updates per vendor instructions. This CVE has been used in known ransomware campaigns. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2019-1579?

CVE-2019-1579 is classified as CWE-134 (CWE-134). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.
