Exploited in the last 30 days

Multiple buffer overflow vulnerabilities in the User-ID Terminal Server Agent (TSA) component of Palo Alto Networks PAN-OS software allow an unauthenticated attacker with network access to cause a denial of service (DoS) condition or potentially execute arbitrary code by sending specially crafted network traffic. The security risk posed by this issue is minimized when the User-ID Terminal Server Agent connectivity is restricted to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://docs.paloaltonetworks.com/ngfw/help/10-2/user-identification/device-user-identification-terminal-services-agents#:~:text=To%20minimize%20security%20risk%2C%20restrict%20TS%20Agent%20connectivity%20to%20trusted%20internal%20IP%20addresses%20only. . Panorama is not impacted by this vulnerability.
