Description
The Palo Alto Networks firewalls API browser does not properly use the REST API tokens. In a specific scenario, an attacker could steal the authentication token and perform calls to the firewall’s API. (Ref # PAN-61046/PAN-100428)
This post-authentication issue requires the attacker to have access to a logged-in administrator’s browser.
This issue affects PAN-OS 5.0.19 and earlier; PAN-OS 5.1.12 and earlier; PAN-OS 6.0.14 and earlier; PAN-OS 6.1.14 and earlier; PAN-OS 7.0.10 and earlier; PAN-OS 7.1.4 and earlier
