PAN-OS 9.0.10 Addressed Issues

Fixed an issue where the firewall added a redundant 0\r\n packet while processing Clientless VPN traffic.

Fixed an issue where a process (authd) restarted when an administrator authenticated to the firewall with an Active Directory (AD) account. This issue occurred when LDAP was configured with FQDN, used DHCP instead of a static management IP address, and used the management interface to connect to the LDAP server.

Fixed an issue where dataplane processes restarted when attempting to access websites that had the NotBefore attribute less than or equal to Unix Epoch Time in the server certificate with forward proxy enabled.

A fix was made to address an OS command injection and memory corruption vulnerability in the PAN-OS management web interface that allowed authenticated administrators to disrupt system processes and execute arbitrary code and OS commands with root privileges (CVE-2020-2000).

(PA-7000 Series firewalls only) Added CLI commands to enable/disable resource-control groups and CLI commands to set an upper memory limit of 8G on a process (mgmtsrvr). To enable resource-control groups, use debug software resource-control enable and to disable them, use debug software resource-control disable. To set the memory limit, use debug management-server limit-memory enable, and to remove the limit, use debug management-server limit-memory disable. For the memory limit change to take effect, the firewall must be rebooted.

Fixed an issue where the reply to an XML API call from Panorama was in a different format after upgrading to PAN-OS 8.1.14-h1 and later releases, which caused automated systems to fail the API call.

Fixed an issue on Panorama where the web interface took more time than expected to load changes when the virtual router was large or when there was a large configuration change request from the web interface.

Fixed an issue where XML API failed to fetch logs larger than 10MB.

A fix was made to address an uncontrolled resource consumption vulnerability in PAN-OS that allowed for a remote unauthenticated user to upload temporary files through the management web interface that were not properly deleted after the request was finished. An attacker could disrupt the availability of the management web interface by repeatedly uploading files until available disk space was exhausted (CVE-2020-2039).

Fixed an issue where the panlogs directory reached 100% utilization on the firewall due to early calculation of the .size file.

Fixed an issue for PAN-DB where certain situations caused performance issues.

(PA-7000b Series firewalls only) Fixed a buffer overflow issue.

Fixed an issue with internal buffer and file sizes where logs were discarded due to slow log purging when the incoming log rate was high.

Fixed an issue where Panorama in Legacy mode rebooted due to multiple process (reportd) restarts.

Fixed an issue with one-way audio for inbound voice calls due to incorrect source port translation.

Fixed an issue where API calls did not return the output for the operational command for running configurations.

A fix was made to address a vulnerability involving information exposure through log files where sensitive fields were recorded in the configuration log without masking on PAN-OS software when the after-change-detail custom syslog field was enabled for configuration logs and the sensitive field appeared multiple times in one log entry. The first instance of the sensitive field was masked but subsequent instances were left in clear text (CVE-2020-2043).

Fixed an issue where exporting logs from the web interface did not generate a system log entry.

After upgrading to certain PAN-OS 8.1 and 9.0 versions, for certain configurations using dynamic routing without graceful restart and with Bidirectional Forwarding Detection (BFD) enabled, there was a longer traffic hit after a high availability (HA) failover compared to previous versions. This was due to BFD incorrectly timing admin-down messages for the failover event.

Fixed an issue where, after upgrading the passive firewall, the stream control transmission protocol (SCTP) sessions synced from the active firewall did not retain the rule information, and, after failover, SCTP stateful inspection did not work.

Fixed an issue on the firewalls where traffic originating from a GlobalProtect user did not match host information profile (HIP) based Security policies using the cached HIP report. Instead, the traffic was denied until the GlobalProtect agent submitted a new HIP report about 20 seconds later.

Fixed an issue where a process (all_pktproc) restarted while processing SSL VPN sessions.

Fixed an issue where an inconsistent PAN-DB cloud connection caused the firewall to negotiate the incorrect version and decode the cloud responses with the incorrect format.

Fixed an issue where the HA peer device did not preserve its import configuration when the mode was active/active and VR sync was disabled.

Fixed an issue where Panorama running 9.0.8 allowed a user with the admin role Device Group and Template to create templates and template stacks.

Fixed an issue on the firewalls where a process (all_task) stopped responding.

Fixed an issue where the firewall generated GPRS tunneling protocol (GTP) logs for invalid GTP packets. This fix also implements a counter, flow_gtp_invalid_ver, where the invalid packets are counted.

Fixed an issue where the multi-factor authentication (MFA) timestamp was not redistributed across the virtual system (vsys) when the IP address-to-user mapping type was UIA.

Fixed an issue where, when previewing device group configurations from Panorama, the following error message was returned: Parameter device group missing.

Fixed an issue where traffic matched an incorrect URL filtering profile due to a similarity in the MD5 hashes between the URL filtering profiles.

Fixed an issue where, when any change was made to an authentication profile, the LDAP server or local user database in a shared context removed the user group mapping information from the firewall.

Fixed an issue where a firewall running in FIPS mode was unable to download the GlobalProtect datafile even when a GlobalProtect license was installed and valid.

Fixed an issue in multi-vsys firewalls where traffic did not match an FQDN address group based policy.

Fixed an memory issue associated with a process (mgmtsrvr) due to a large number of ACK packets in logs on Panorama or the log collector.

Fixed an issue where Amazon Web Services (AWS) Nitro System based VM-Series firewalls unexpectedly rebooted due to input/output (I/O) errors caused by improper NMVE I/O timeout settings.

Fixed an issue where the locked users list grew too large, which caused 100% CPU usage on a process (authd). With this fix, locked users will be purged hourly if the lockout time for that user has expired.

Fixed an issue on Panorama where commits failed, referring to a portion of the configuration that was not changed.

Fixed an issue where a process (brdagent) failed in an HA configuration using High Speed Chassis Interconnect (HSCI) ports due to a memory leak.

Fixed an issue where a process (*mprelay*) stopped responding and invoked an out-of-memory (OOM) killer condition and displayed the following error messages: `tcam full` and `pan_plfm_fe_cp_arp_delete`.

Fixed an issue where the firewalls faced connection issues with Cortex Data Lake.

Fixed an internal logging issue for a daemon (authd).

Fixed an issue where promiscuous VLAN mode did not work with the new host drivers being used on the ESXi and single-root input/output virtualization (SR-IOV) with VLAN tagging did not work as expected. Both Data Plane Development Kit and packet mmap mode did not work.

Fixed an issue where dataplane free memory was depleted, which affected new GlobalProtect connections to the firewall.

Fixed an issue where a commit or content update operation with an error was not prevented from executing in the dataplane, which caused corruption in the dataplane policy cache.

Fixed an issue where the HTTP/2 stream method was no longer valid after overloading the same pointer to point to either the HTTP/2 stream or the proxy flow.

(PA-7000 Series firewalls only) Fixed an issue where a process (mprelay) on the control plane was restarted due to an internal heartbeat miss.

Fixed an issue where the firewall failed to establish SFTP firewall-server connections when SSH decryption was enabled.

Fixed an issue on Panorama in Legacy mode where configuring Network File System (NFS) log storage (Device > Setup > Operations) caused all plugin installations to fail.

Fixed an issue where a process (logrcvr) exited due to a race condition.

(PA-7000 Series firewalls only) Enhanced latency-sensitive protocols processing. With this fix, the following latency-sensitive control traffic will be prioritized: BGP, BFD, LACP, OSPF, OSPFv3, Protocol Independent Multicast (PIM), and Internet Group Management Protocol (IGMP).

Fixed an issue where the Elasticsearch cluster status displayed in yellow due to a missing replica serial number.

Fixed an issue where response pages generated from the firewall used the SMAC and DMAC addresses from the original packet, which caused a MAC flap on connected switches.

Fixed an issue that prevented the addition of a secondary logging disk for a VM-Series firewall deployed on AWS using Nitro server instance types.

Fixed an issue where the host information profile (HIP) match message was automatically enabled when modifying the GlobalProtect Agent settings.

Fixed an issue where virtual machine (VM) information source Dynamic Address Groups overrode static address groups, which caused traffic to hit the wrong Security policy rule.

(VM-Series firewalls in Microsoft Azure environment only) Fixed an issue where a firewall with accelerated networking enabled was unable to process packets efficiently because of underlying Microsoft drivers. To leverage this fix, you must upgrade to VM-Series Plugin 1.0.12.

Fixed an issue where the show config diff CLI command did not work correctly and produced unexpected output.

Fixed an issue where access was denied if a password contained more than 63 characters.

Fixed an issue where, on a firewall managed by Panorama, the XML API based IP tags were lost after a firewall reboot or process (useridd) restart.

Fixed an issue for S11 traffic where if the Modify Bearer Request message came after 30 seconds of Create Session Response message, the firewall dropped the Modify Bearer Request packet. This fix increases this time to 90 seconds.

Fixed an issue on the firewall where the dataplane pan-task process (all_pktproc) stopped responding while inspecting Server Message Block (SMB) traffic.

Fixed an issue where a process (useridd) failed due to internal user groups that were loading from the disk taking over the lock.

Fixed an issue where clientless VPN rewrite failed due to incorrect parsing of the HTML webpage.

Fixed an intermittent issue where Panorama was unable to query logs from the log collector due to large file sizes in es_cache_cron.log.

Fixed an issue on Panorama where administrators were unable to delete a shared address object even when it was not referenced in the configuration.

Fixed an issue on the firewall where configuring uppercase User Domain values in authentication profiles led to a failure in GlobalProtect Agent configuration selection based on the domain user match condition.

Fixed an issue where policies that contained objects did not display correctly when exported to CSV or PDF format.

Fixed an issue where the paths between the control plane and the dataplanes in network processing cards (NPCs) stalled in the dataplane-to-control plane direction due to the Ring Descriptor entries becoming out of sync on each side. This produced unrecoverable data path monitoring failures, which caused the chassis to become nonfunctional.

Fixed an issue where all NAT rules using the same FQDN entries as translated IP addresses were not updated when the IP addresses changed for those FQDNs.

A fix was made to address a vulnerability involving information exposure through log files where an administrator's password or other sensitive information was logged in cleartext while using the CLI in PAN-OS software. The opcmdhistory.log file was introduced to track operational command (op-command) usage but did not mask all sensitive information (CVE-2020-2044).

Fixed an issue where setting an IPv6 destination filter for the packet-diag option returned an error regarding a character limit.

Fixed an issue where using a session_proxy() without checking that it actually is a proxy led to a dataplane process restart.

Fixed an issue with a memory leak in a process (user-id) due to failed LDAP over SSL (LDAPS) requests.

Fixed an issue where Resolve (Objects > Addresses > <Name>) in the web interface did not work for FQDN address objects with more than 63 characters.

Fixed an issue where Safe Search was not enabled after an application change.

(VM-Series firewalls only) Fixed an issue where the VLAN interface failed to obtain the MAC address when the interface was used as a DHCP relay agent.

Fixed an issue where a process (all_pktproc) restarted while processing Clientless VPN traffic.

Fixed an issue where custom signatures did not properly detect the User-Agent header when the Origin header was above the User-Agent header.

Fixed an issue on Panorama where configuring a BGP import rule from the CLI failed with the following error message: Server error : permission denied for the command set.

Fixed an issue where querying traffic logs based on address objects and address groups did not work.

Fixed an issue where RADIUS authentication failed due to an FQDN resolution failure after the VM-Series firewall rebooted.

Fixed an issue that caused a procses (ikemgr) to exit when site-to-site VPNs experienced connectivity interruptions.

Fixed an issue where the Authentication Portal did not work due to a large number of HTTP requests with unsupported Authorization headers.

Fixed an issue on the firewalls where configuring a default Online Certificate Status Protocol (OCSP) URL in front of an intermediate certificate authority (CA) in a certificate profile did not override the OCSP URL during the validation of client certificates issued by the intermediate CA.

Fixed an issue where service objects were unable to be deleted if they were configured to exceed firewall limits.

Fixed an issue where a child dynamic address group was not added as a member of the parent group.

Fixed an issue where the GlobalProtect portal did not generate certificate signing requests (CSRs) due to failed Simple Certificate Enrollment Protocol (SCEP) authentication cookie validation.

Fixed an issue where both firewalls in an HA active/passive configuration stopped responding at the same time.

Fixed an issue where the firewall did not recognize a device when the DHCP contained a hostname with a trailing NULL.

Fixed an issue where the ACC risk meter displayed as zero for long time periods with a large amount of logs.

Fixed an issue where a rare cleartext HTTP/2 application behavior caused a resource leak. If jumbo frames were enabled, this leak caused the App-ID queue to fill up quickly, which led to legitimate sessions being discarded.

Fixed an issue where the session ID did not display correctly in the debug logs related to the hardware security module (HSM).

Fixed an issue where, in VM-Series firewalls deployed using init-cfg.txt in the bootstrap process and set in an HA configuration, the configuration did not display as synchronized due to the initcfg configuration.

Fixed an issue where a process (pan_comm) stopped responding due to operation commands run during a commit.

Fixed an issue where a process (mgmtsrvr) restarted due to race conditions initialized by the mutex.

Fixed an issue where excessive next hop FPGA exceptions occurred when an ARP request or response was lost in the network in an ECMP configuration, which blocked subsequent ARP learning due to a full queue.

Fixed an issue on Panorama where the Policy Optimizer showed invalid data for Rule Usage.

Enhanced a daemon (dnsproxy) to support DNS compression for query strings.

A fix was made to address an OS command injection vulnerability in the PAN-OS management interface that allowed authenticated administrators to execute arbitrary OS commands with root privileges (CVE-2020-2037).

Fixed an issue where selecting Preview Changes under a specific device group resulted in the following error message: Parameter device group missing.

Fixed an issue where the dynamic address group failed due to a process (devsrvr) not being synced with another process (useridd).

Fixed an issue where the dataplane maintained the old category for the URL even after changing or deleting that category from PAN-DB.

Fixed an issue where multiple daemons restarted due to MP ARP overflow.

Fixed an issue where the XML API used to retrieve hardware status periodically failed with a 200 OK message and no data.

Fixed an issue where a Panorama appliance running PAN-OS 10.0.0 observed restarts in a process (reportd) while running a custom report when the log collector or remote device was running a software version earlier than the current version on Panorama.

Fixed an issue where Elasticsearch failed to properly start up, which caused issues with logging on Panorama or the Log Collector.

(VM-Series firewalls on VMware ESXi only) Fixed an issue where the firewall stays in a boot loop and enters maintenance mode after adding a 60GB disk.

(Japanese language only) Fixed an issue where the WildFire Update Schedule incorrectly displayed At as Atlantic.

Fixed an issue on Panorama where, when navigating through Policies, the following error message displayed: show rule hit count op-command failed.

Fixed an issue where commits failed with the following error: Error unserializing profile objects failed to handle CONFIG_UPDATE_START.

Fixed an intermittent issue where configuration audit stopped showing commit history and revisions.

Fixed an issue where the firewall stopped forwarding logs to the log collector from the Log Processing Card (LPC) after a commit push from Panorama due to a race condition.

Fixed an issue on the firewalls where a process (mgmtsrvr) restarted after the Panorama connection flapped.
