A vulnerability in the GlobalProtect Gateway in Palo Alto Networks PAN-OS software enables an authenticated attacker to impersonate another user and send network packets to internal assets. However, this vulnerability does not allow the attacker to receive response packets from those internal assets.

An incorrect string comparison vulnerability in Palo Alto Networks PAN-OS software prevents Predefined Decryption Exclusions from functioning as intended. This can cause traffic destined for domains that are not specified in Predefined Decryption Exclusions to be unintentionally excluded from decryption.

A packet processing mechanism in Palo Alto Networks PAN-OS software enables a remote attacker to reboot hardware-based firewalls. Repeated attacks eventually cause the firewall to enter maintenance mode, which requires manual intervention to bring the firewall back online. This affects the following hardware firewall models: - PA-5400 Series firewalls - PA-7000 Series firewalls

A reflected cross-site scripting (XSS) vulnerability in the GlobalProtect portal feature of Palo Alto Networks PAN-OS software enables execution of malicious JavaScript (in the context of a user’s browser) if a user clicks on a malicious link, allowing phishing attacks that could lead to credential theft.

Web sessions in the management interface in Palo Alto Networks PAN-OS software do not expire in certain situations, making it susceptible to unauthorized access.
