✅ Remediation
VERSION MINOR VERSION SUGGESTED SOLUTION PAN-OS 11.2 11.2.0 through 11.2.2 Upgrade to 11.2.3 or later PAN-OS 11.1 11.1.0 through 11.1.4 Upgrade to 11.1.5 or later PAN-OS 11.0 11.0.0 through 11.0.5 Upgrade to 11.0.6 or later PAN-OS 10.2 10.2.0 through 10.2.10 Upgrade to 10.2.11 or later PAN-OS 10.1 10.1.0 through 10.1.14 Upgrade to 10.1.14-h11 or later All other older Upgrade to a supported fixed version. unsupported PAN-OS versions PAN-OS 11.0 is EoL. We listed it in this section for completeness because we added a patch for PAN-OS 11.0 before it reached EoL. If you are running PAN-OS 11.0 in any of your firewalls, we strongly recommend that you upgrade to a fixed supported version. We proactively initiated the upgrade through Prisma Access March 21, 2025, to cover all tenants. Workarounds and mitigations: If you are not using SCEP, you can disable it to mitigate this risk by running the following command in your PAN-OS command-line interface (CLI): > debug sslmgr set disable-scep-auth-cookie yes CAUTION: This workaround is effective only until the next reboot, after which you must rerun this command to stay protected.
