A null pointer dereference vulnerability in Palo Alto Networks PAN-OS software enables an unauthenticated attacker to stop a core system service on the firewall by sending a crafted packet through the data plane that causes a denial of service (DoS) condition. Repeated attempts to trigger this condition result in the firewall entering maintenance mode.

A null pointer dereference vulnerability in the GlobalProtect gateway in Palo Alto Networks PAN-OS software enables an unauthenticated attacker to stop the GlobalProtect service on the firewall by sending a specially crafted packet that causes a denial of service (DoS) condition. Repeated attempts to trigger this condition result in the firewall entering maintenance mode.

A privilege escalation (PE) vulnerability in the XML API of Palo Alto Networks PAN-OS software enables an authenticated PAN-OS administrator with restricted privileges to use a compromised XML API key to perform actions as a higher privileged PAN-OS administrator. For example, an administrator with "Virtual system administrator (read-only)" access could use an XML API key of a "Virtual system administrator" to perform write operations on the virtual system configuration even though they should be limited to read-only operations.

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.

An OS command injection vulnerability in Palo Alto Networks Expedition 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.

A vulnerability in the GlobalProtect portal in Palo Alto Networks PAN-OS software enables a malicious authenticated GlobalProtect user to impersonate another GlobalProtect user. Active GlobalProtect users impersonated by an attacker who is exploiting this vulnerability are disconnected from GlobalProtect. Upon exploitation, PAN-OS logs indicate that the impersonated user authenticated to GlobalProtect, which hides the identity of the attacker.

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.

A command injection vulnerability in Palo Alto Networks PAN-OS software enables an authenticated administrator to bypass system restrictions and run arbitrary commands as root on the firewall.

An information exposure vulnerability in Palo Alto Networks PAN-OS software enables a local system administrator to unintentionally disclose secrets, passwords, and tokens of external systems. A read-only administrator who has access to the config log, can read secrets, passwords, and tokens to external systems.
