PAN-OS® 9.1.10 addressed issues.
Issue ID
Fixed an issue where a firewall in FIPS mode running PAN-OS 8.1.18 or a later version failed to connect with a WildFire appliance in normal mode.
Fixed an issue where cloud queries failed, which generated system logs. The issue occurred because a hash was not found in the cloud.
Fixed an issue where custom URL categories hit incorrect URL categories, which caused the firewall to miss or deny the security policies for the configured custom URL.

Fixed an issue where commit jobs failed when validating HIP objects and profiles.
Fixed an issue where an unavailable certificate revocation list (CRL) from the server side caused an infinite loop on a process (sslmgr), which resulted in it not responding for other tasks.
A fix was made to address an improper restriction of XML external identity (XXE) reference in the PAN-OS web interface that enabled an authenticated administrator to read any arbitrary file from the file system and send a specifically crafted request to the firewall that caused the service to crash (CVE-2021-3055).

Device Name
field was missing when GlobalProtect logs were exported to CSV from the Panorama management server.
Fixed a memory leak issue related to a process (useridd) that occurred when processing high amount of HIP reports as well as aa memory leak issue related to the sslvpn process that occurred when the firewall was configured as a GlobalProtect satellite.
Fixed an issue where a process (useridd) repeatedly exceeded the virtual memory limit, which caused the process to stop responding.
Fixed an issue in Panorama where an administrator with the role of Panorama administrator did not have the option to download or install GlobalProtect clients (

in the
and pushed from Panorama template stack values. To utilize this fix, you must upgrade both Panorama and the firewall.
ZTP-capable firewalls only

Fixed an issue where you were unable to add more than 500 DHCP relay agent objects in the firewall templates from Panorama.
Fixed an issue where an increase was observed on
, which caused latency.

Failed to get DLSRVR client key
. This issue occurred only on firewalls where the
request system-private-data-reset
CLI command had been issued in the past.

Fixed an issue where, when stateless GTP-U traffic hit a multi-dataplane firewall, an inter-dataplane fragmentation loop occurred, which caused high dataplane resource usage.
A fix was made to address an issue where a cryptographically weak pseudo-random number (PRNG) was used during authentication to the PAN-OS interface. As a result, attackers with the capability to observe their own authentication secrets over a long duration on the firewall had the ability to impersonate another authenticated web interface administrator’s session (CVE-2021-3047).
Fixed an issue where the management interface incorrectly used the configured default gateway for local network traffic when service routes were configured.

Fixed an issue where using XML special characters in the
Uninstalled GlobalProtect APP
password in the application configuration (

) disrupted portal connectivity.
Fixed an issue where the firewall treated external dynamic list entries with nested carets as invalid.
Fixed an issue where, after upgrading Panorama from PAN-OS 8.1.9 to PAN-OS 9.1.3, the option to preview changes for dynamic address groups or templates from Panorama did not work.
Fixed an issue where the software QoS shaping queue processing was not properly applied on multicast traffic.
Fixed an issue where, when IPSec tunnels had
enabled, tunnel activation was sent every 3 seconds, even when the configured value was different. With this fix, tunnel activation will be sent according to the configured intervals and thresholds.

PA-220 Series firewalls only
) Fixed an issue where a process (mgmtsrvr) stopped responding when viewing logs in the web interface.
A fix was made to address a reflect cross-site scripting (XSS) vulnerability in the PAN-OS web interface that enabled an authenticated network-based attacker to mislead another authenticated PAN-OS administrator to click on a specially crafted link that performed arbitrary actions in the web interface as the targeted authenticated administrator (CVE-2021-3052).
Fixed an issue where Elasticsearch restarted unexpectedly when it ran out of memory. This was due to the
value being set incorrectly in the newer version of Elasticsearch (starting from PAN-OS 9.0). With this fix, the value is set correctly.
Fixed an issue where, even when tunnel interface is set to
, the following alert displayed:
Tunnel GRE_Tunnels is going down(critical)
Fixed an issue where a process (authd) ignored null domain authentication profiles in a sequence and only returned non-null domains to GlobalProtect.

Fixed an issue on the firewall web interface where the Cortex Data Lake
Logging Service Status
pop-up window did not show correct information.
Fixed an issue with the Panorama web interface where, when all device groups and templates were selected, a load configuration operation failed. This was caused by the XML cache rebuilding for each device group and template iteration.
Fixed an issue where, in two separate but simultaneous sessions, the same software packet buffer was owned and processed.
Fixed an issue where a satellite firewall was unable to authenticate to an LSVPN gateway when the issued certificate from Simple Certificate Enrollment Protocol (SCEP) had encryption bits set to 3072.

Fixed an issue where administrators were unable to delete the
GlobalProtect Data File
update schedule (
Device > Dynamic Updates
Fixed an issue where merged configurations were unable to be exported from Panorama-managed firewalls using the PAN-OS XML API.
Fixed a rare issue where, when aggregate ethernet (AE) groups were deleted and re-added, the AE interface no longer had an SDB node to send link the location to. As a result, the dataplane was unable to identify a connected route for the interface address.
Fixed an issue where the firewall status was inaccurate (
Panorama > Device Deployment
Fixed an issue memory leak issue where a process (devsrvr) consumed excess memory, which resulted in OOM conditions.
