CISA Known Exploited Vulnerabilities Directory

Palo Alto Networks PAN-OS contains an authentication bypass vulnerability that allows attackers to bypass security restrictions and establish an unauthorized VPN connection.

Palo Alto Networks PAN-OS contains an out-of-bounds write vulnerability in the User-ID Authentication Portal (aka Captive Portal) service that can allow an unauthenticated attacker to execute arbitrary code with root privileges on the PA-Series and VM-Series firewalls by sending specially crafted packets.

Palo Alto Networks PAN-OS contains an external control of file name or path vulnerability. Successful exploitation enables an authenticated attacker with network access to the management web interface to read files on the PAN-OS filesystem that are readable by the “nobody” user.

Palo Alto Networks PAN-OS contains an authentication bypass vulnerability in its management web interface. This vulnerability allows an unauthenticated attacker with network access to the management web interface to bypass the authentication normally required and invoke certain PHP scripts.

Palo Alto Networks PAN-OS contains a vulnerability in parsing and logging malicious DNS packets in the DNS Security feature that, when exploited, allows an unauthenticated attacker to remotely reboot the firewall. Repeated attempts to trigger this condition will cause the firewall to enter maintenance mode.

Palo Alto Networks PAN-OS contains an authentication bypass vulnerability in the web-based management interface for several PAN-OS products, including firewalls and VPN concentrators.

Palo Alto Networks PAN-OS contains an OS command injection vulnerability that allows for privilege escalation through the web-based management interface for several PAN products, including firewalls and VPN concentrators.

Palo Alto Networks PAN-OS GlobalProtect feature contains a command injection vulnerability that allows an unauthenticated attacker to execute commands with root privileges on the firewall.

A Palo Alto Networks PAN-OS URL filtering policy misconfiguration could allow a network-based attacker to conduct reflected and amplified TCP denial-of-service (RDoS) attacks.

Palo Alto Networks PAN-OS contains multiple, unspecified vulnerabilities which can allow for remote code execution when chained.
