How do I detect CVE-2019-1579 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

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

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

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 46.2%, placing it in the 99th 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.
