An improper neutralization of matching symbols vulnerability in the Palo Alto Networks PAN-OS command line interface (CLI) enables authenticated administrators (including read-only administrators) with access to the CLI to to read arbitrary files on the firewall.

An information exposure vulnerability exists in Palo Alto Networks PAN-OS software that enables a GlobalProtect end user to learn both the configured GlobalProtect uninstall password and the configured disable or disconnect passcode. After the password or passcode is known, end users can uninstall, disable, or disconnect GlobalProtect even if the GlobalProtect app configuration would not normally permit them to do so.

An incorrect string comparison vulnerability in Palo Alto Networks PAN-OS software prevents Predefined Decryption Exclusions from functioning as intended. This can cause traffic destined for domains that are not specified in Predefined Decryption Exclusions to be unintentionally excluded from decryption.

A vulnerability in Palo Alto Networks PAN-OS software enables a remote attacker to reboot PAN-OS firewalls when receiving Windows New Technology LAN Manager (NTLM) packets from Windows servers. Repeated attacks eventually cause the firewall to enter maintenance mode, which requires manual intervention to bring the firewall back online.

A reflected cross-site scripting (XSS) vulnerability in the Captive Portal feature of Palo Alto Networks PAN-OS software enables execution of malicious JavaScript (in the context of an authenticated Captive Portal user’s browser) if a user clicks on a malicious link, allowing phishing attacks that could lead to credential theft.

Web sessions in the management interface in Palo Alto Networks PAN-OS software do not expire in certain situations, making it susceptible to unauthorized access.

A cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software enables a malicious authenticated read-write administrator to store a JavaScript payload using the web interface on Panorama appliances. This enables the impersonation of another authenticated administrator.

An OS command injection vulnerability in Palo Alto Networks PAN-OS software enables an authenticated administrator to disrupt system processes and potentially execute arbitrary code with limited privileges on the firewall.

An improper privilege management vulnerability in Palo Alto Networks PAN-OS software enables an authenticated read-only administrator to revoke active XML API keys from the firewall and disrupt XML API usage.

An OS command injection vulnerability in the XML API of Palo Alto Networks PAN-OS software enables an authenticated API user to disrupt system processes and potentially execute arbitrary code with limited privileges on the firewall.

A credential disclosure vulnerability in Palo Alto Networks PAN-OS software enables an authenticated read-only administrator to obtain the plaintext credentials of stored external system integrations such as LDAP, SCP, RADIUS, TACACS+, and SNMP from the web interface.

A DOM-Based cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software enables a remote attacker to execute a JavaScript payload in the context of an administrator’s browser when they view a specifically crafted link to the PAN-OS web interface.

A reflected cross-site scripting (XSS) vulnerability in the Captive Portal feature of Palo Alto Networks PAN-OS software can allow a JavaScript payload to be executed in the context of an authenticated Captive Portal user’s browser when they click on a specifically crafted link.

A file disclosure vulnerability in Palo Alto Networks PAN-OS software enables an authenticated read-write administrator with access to the web interface to export local files from the firewall through a race condition.

A vulnerability in Palo Alto Networks PAN-OS software enables an authenticated administrator to expose the plaintext values of secrets stored in the device configuration and encrypted API keys.

A local file deletion vulnerability in Palo Alto Networks PAN-OS software enables an authenticated administrator to delete files from the local file system with elevated privileges. These files can include logs and system components that impact the integrity and availability of PAN-OS software.

A PAN-OS URL filtering policy misconfiguration could allow a network-based attacker to conduct reflected and amplified TCP denial-of-service (RDoS) attacks. The DoS attack would appear to originate from a Palo Alto Networks PA-Series (hardware), VM-Series (virtual) and CN-Series (container) firewall against an attacker-specified target. To be misused by an external attacker, the firewall configuration must have a URL filtering profile with one or more blocked categories assigned to a source zone that has an external facing interface. This configuration is not typical for URL filtering and, if set, is likely unintended by the administrator. If exploited, this issue would not impact the confidentiality, integrity, or availability of our products. However, the resulting denial-of-service (DoS) attack may help obfuscate the identity of the attacker and implicate the firewall as the source of the attack. We have taken prompt action to address this issue in our PAN-OS software. All software updates for this issue are expected to be released no later than the week of August 15, 2022. This issue does not impact Panorama M-Series or Panorama virtual appliances. This issue has been resolved for all Cloud NGFW and Prisma Access customers and no additional action is required from them.

A vulnerability exists in Palo Alto Networks PAN-OS software that enables an authenticated network-based PAN-OS administrator to upload a specifically created configuration that disrupts system processes and potentially execute arbitrary code with root privileges when the configuration is committed on both hardware and virtual firewalls. This issue does not impact Panorama appliances or Prisma Access customers. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.23; PAN-OS 9.0 versions earlier than PAN-OS 9.0.16; PAN-OS 9.1 versions earlier than PAN-OS 9.1.13; PAN-OS 10.0 versions earlier than PAN-OS 10.0.10; PAN-OS 10.1 versions earlier than PAN-OS 10.1.5.

An improper handling of exceptional conditions vulnerability exists in the DNS proxy feature of Palo Alto Networks PAN-OS software that enables a meddler-in-the-middle (MITM) to send specifically crafted traffic to the firewall that causes the service to restart unexpectedly. Repeated attempts to send this request result in denial-of-service to all PAN-OS services by restarting the device in maintenance mode. This issue does not impact Panorama appliances and Prisma Access customers. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.22; PAN-OS 9.0 versions earlier than PAN-OS 9.0.16; PAN-OS 9.1 versions earlier than PAN-OS 9.1.13; PAN-OS 10.0 versions earlier than PAN-OS 10.0.10; PAN-OS 10.1 versions earlier than PAN-OS 10.1.5. This issue does not impact PAN-OS 10.2.

PAN-OS software provides options to exclude specific websites from URL category enforcement and those websites are blocked or allowed (depending on your rules) regardless of their associated URL category. This is done by creating a custom URL category list or by using an external dynamic list (EDL) in a URL Filtering profile. When the entries in these lists have a hostname pattern that does not end with a forward slash (/) or a hostname pattern that ends with an asterisk (*), any URL that starts with the specified pattern is considered a match. Entries with a caret (^) at the end of a hostname pattern match any top level domain. This may inadvertently allow or block more URLs than intended and allowing more URLs than intended represents a security risk. For example: example.com will match example.com.website.test example.com.* will match example.com.website.test example.com.^ will match example.com.test You should take special care when using such entries in policy rules that allow traffic. Where possible, use the exact list of hostname names ending with a forward slash (/) instead of using wildcards. PAN-OS 10.1 versions earlier than PAN-OS 10.1.3; PAN-OS 10.0 versions earlier than PAN-OS 10.0.8; PAN-OS 9.1 versions earlier than PAN-OS 9.1.12; all PAN-OS 9.0 versions; PAN-OS 8.1 versions earlier than PAN-OS 8.1.21, and Prisma Access 2.2 and 2.1 versions do not allow customers to change this behavior without changing the URL category list or EDL.
