CVE-2021-3048

Name of the Vulnerable Software and Affected Versions PAN-OS versions prior to 9.0.14 PAN-OS versions prior to 9.1.9 PAN-OS versions prior to 10.0.5

Description The issue is caused by certain invalid URL entries contained in an External Dynamic List (EDL) that cause the Device Server daemon (devsrvr) to stop responding. This condition leads to failed commits on the firewall and prevents administrators from performing commits and configuration changes, even though the firewall remains otherwise functional. If the firewall then restarts, it results in a denial-of-service (DoS) condition and the firewall stops processing traffic.

Recommendations For PAN-OS versions prior to 9.0.14, update to version 9.0.14 or later. For PAN-OS versions prior to 9.1.9, update to version 9.1.9 or later. For PAN-OS versions prior to 10.0.5, update to version 10.0.5 or later.
