CVE Vulnerabilities

Status Master

CVE-2020-1982

Certain communication between PAN-OS and cloud-delivered services inadvertently use TLS 1.0, which is known to be a cryptographically weak protocol. These cloud services include Cortex Data Lake, the Customer Support Portal, and the Prisma Access infrastructure. Conditions required for exploitation of known TLS 1.0 weaknesses do not exist for the communication between PAN-OS and cloud-delivered services. We do not believe that any communication is impacted as a result of known attacks against TLS 1.0. This issue impacts: All versions of PAN-OS 8.0; PAN-OS 8.1 versions earlier than PAN-OS 8.1.14; PAN-OS 9.0 versions earlier than PAN-OS 9.0.9; PAN-OS 9.1 versions earlier than PAN-OS 9.1.3. PAN-OS 7.1 is not impacted by this issue.

Status Master

CVE-2020-2030

An OS Command Injection vulnerability in the PAN-OS management interface that allows authenticated administrators to execute arbitrary OS commands with root privileges. This issue impacts PAN-OS 8.1 versions earlier than PAN-OS 8.1.15; and all versions of PAN-OS 7.1 and PAN-OS 8.0. This issue does not impact PAN-OS 9.0, PAN-OS 9.1, or Prisma Access services.

Status Master

CVE-2020-2031

An integer underflow vulnerability in the dnsproxyd component of the PAN-OS management interface allows authenticated administrators to issue a command from the command line interface that causes the component to stop responding. Repeated attempts to send this request result in denial of service to all PAN-OS services by restarting the device and putting it into maintenance mode. This issue impacts: PAN-OS 9.1 versions earlier than PAN-OS 9.1.3. This issue does not impact PAN-OS 8.1, PAN-OS 9.0, or Prisma Access services.

Status Master

CVE-2020-2034

An OS Command Injection vulnerability in the PAN-OS GlobalProtect portal allows an unauthenticated network based attacker to execute arbitrary OS commands with root privileges. An attacker requires some knowledge of the firewall to exploit this issue. This issue can not be exploited if GlobalProtect portal feature is not enabled. This issue impacts PAN-OS 9.1 versions earlier than PAN-OS 9.1.3; PAN-OS 8.1 versions earlier than PAN-OS 8.1.15; PAN-OS 9.0 versions earlier than PAN-OS 9.0.9; all versions of PAN-OS 8.0 and PAN-OS 7.1. Prisma Access services are not impacted by this vulnerability.
