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 Expedition contains an OS command injection vulnerability that allows an unauthenticated attacker to run arbitrary OS commands as root in Expedition, resulting in disclosure of usernames, cleartext passwords, device configurations, and device API keys of PAN-OS firewalls.

Palo Alto Networks Expedition contains a SQL injection vulnerability that allows an unauthenticated attacker to reveal Expedition database contents, such as password hashes, usernames, device configurations, and device API keys. With this, attackers can also create and read arbitrary files on the Expedition system.

Palo Alto Networks Expedition contains a missing authentication vulnerability that allows an attacker with network access to takeover an Expedition admin account and potentially access configuration secrets, credentials, and other data.
