Description
Le titre, la description et les consignes de l’éditeur sont cités depuis les enregistrements sources (en anglais).
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.

Contournement · PAN-OS
The vast majority of firewalls already follow Palo Alto Networks' and industry best practices. However, if you have not already, we strongly recommend that you restrict your User-ID Terminal Server Agent connectivity to only trusted internal IP addresses according to our 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.
