Vulnerabilities (CVE)

A vulnerability in Palo Alto Networks PAN-OS software enables an unauthenticated attacker to cause a denial of service (DoS) to the firewall. Repeated attempts to trigger this issue results in the firewall entering into maintenance mode.

An information disclosure vulnerability in Palo Alto Networks PAN-OS® software enables an authenticated administrator to view session tokens of users authenticated to the firewall web UI. This may allow impersonation of users whose session tokens are leaked.   The security risk posed by this issue is significantly minimized when CLI access is restricted to a limited group of administrators. Cloud NGFW and Prisma® Access are not affected by this vulnerability.

A weak (low bit strength) device certificate in Palo Alto Networks Panorama software enables an attacker to perform a meddler-in-the-middle (MitM) attack to capture encrypted traffic between the Panorama management server and the firewalls it manages. With sufficient computing resources, the attacker could break encrypted communication and expose sensitive information that is shared between the management server and the firewalls.

An arbitrary file upload vulnerability in Palo Alto Networks Panorama software enables an authenticated read-write administrator with access to the web interface to disrupt system processes and crash the Panorama. Repeated attacks eventually cause the Panorama to enter maintenance mode, which requires manual intervention to bring the Panorama back online.

An improper authorization vulnerability in Palo Alto Networks Panorama software enables an authenticated read-only administrator to upload files using the web interface and completely fill one of the disk partitions with those uploaded files, which prevents the ability to log into the web interface or to download PAN-OS, WildFire, and content images. This issue affects only the web interface of the management plane; the dataplane is unaffected.

An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable.

An SQL injection vulnerability in Palo Alto Networks Expedition enables an authenticated attacker to reveal Expedition database contents, such as password hashes, usernames, device configurations, and device API keys. This vulnerability also enables attackers to create and read arbitrary files on the Expedition system.

A reflected cross-site scripting (XSS) vulnerability in Palo Alto Networks Expedition enables attackers to execute malicious JavaScript code in the context of an authenticated Expedition user’s browser if that authenticated user clicks a malicious link that allows phishing attacks and could lead to Expedition browser-session theft.

An arbitrary file deletion vulnerability in Palo Alto Networks Expedition enables an unauthenticated attacker to delete arbitrary files accessible to the www-data user on the host filesystem.

A wildcard expansion vulnerability in Palo Alto Networks Expedition allows an unauthenticated attacker to enumerate files on the host filesystem.

An OS command injection vulnerability in Palo Alto Networks Expedition enables an unauthenticated attacker to run arbitrary OS commands as the www-data user in Expedition, which results in the disclosure of usernames, cleartext passwords, device configurations, and device API keys for firewalls running PAN-OS software.

A memory corruption vulnerability in Palo Alto Networks PAN-OS software allows an unauthenticated attacker to crash PAN-OS due to a crafted packet through the data plane, resulting in a denial of service (DoS) condition. Repeated attempts to trigger this condition will result in PAN-OS entering maintenance mode.

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 ... 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.

When Security Assertion Markup Language (SAML) authentication is enabled and the 'Validate Identity Provider Certificate' option is disabled (unchecked), improper verification of signatures in PAN-OS SAML authentication enables an unauthenticated network-based attacker to access protected resources. The attacker must have network access to the vulnerable server to exploit this vulnerability. This issue affects PAN-OS 9.1 versions earlier than PAN-OS 9.1.3; PAN-OS 9.0 versions earlier than PAN-OS ... When Security Assertion Markup Language (SAML) authentication is enabled and the 'Validate Identity Provider Certificate' option is disabled (unchecked), improper verification of signatures in PAN-OS SAML authentication enables an unauthenticated network-based attacker to access protected resources. The attacker must have network access to the vulnerable server to exploit this vulnerability. This issue affects PAN-OS 9.1 versions earlier than PAN-OS 9.1.3; PAN-OS 9.0 versions earlier than PAN-OS 9.0.9; PAN-OS 8.1 versions earlier than PAN-OS 8.1.15, and all versions of PAN-OS 8.0 (EOL). This issue does not affect PAN-OS 7.1. This issue cannot be exploited if SAML is not used for authentication. This issue cannot be exploited if the 'Validate Identity Provider Certificate' option is enabled (checked) in the SAML Identity Provider Server Profile. Resources that can be protected by SAML-based single sign-on (SSO) authentication are: GlobalProtect Gateway, GlobalProtect Portal, GlobalProtect Clientless VPN, Authentication and Captive Portal, PAN-OS next-generation firewalls (PA-Series, VM-Series) and Panorama web interfaces, Prisma Access In the case of GlobalProtect Gateways, GlobalProtect Portal, Clientless VPN, Captive Portal, and Prisma Access, an unauthenticated attacker with network access to the affected servers can gain access to protected resources if allowed by configured authentication and Security policies. There is no impact on the integrity and availability of the gateway, portal or VPN server. An attacker cannot inspect or tamper with sessions of regular users. In the worst case, this is a critical severity vulnerability with a CVSS Base Score of 10.0 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N). In the case of PAN-OS and Panorama web interfaces, this issue allows an unauthenticated attacker with network access to the PAN-OS or Panorama web interfaces to log in as an administrator and perform administrative actions. In the worst-case scenario, this is a critical severity vulnerability with a CVSS Base Score of 10.0 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). If the web interfaces are only accessible to a restricted management network, then the issue is lowered to a CVSS Base Score of 9.6 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). Palo Alto Networks is not aware of any malicious attempts to exploit this vulnerability.
