A vulnerability exists in the PAN-OS web interface packet capture management that could allow an authenticated user to inject arbitrary commands. (Ref # PAN-81892 / CVE-2017-15940)
PAN-OS contains a vulnerability that may allow for post authentication command injection
PAN-OS 6.1.18 and earlier, PAN-OS 7.0.18 and earlier, PAN-OS 7.1.13 and earlier, PAN-OS 8.0.6 and earlier
PAN-OS 6.1.19 and later, PAN-OS 7.0.19 and later, PAN-OS 7.1.14 and later, PAN-OS 8.0.6-h3 and later
Palo Alto Networks has released content update 765 including vulnerability signatures #30998 that can be used as an interim mitigation to protect PAN-OS devices until the device software is upgraded. Note that signatures 30998 must be applied to a firewall rule securing traffic destined for the Management interface. This issue affects the management interface of the device and is strongly mitigated by following best practices for the isolation of management interfaces for security appliances. We recommend that the management interface be isolated and strictly limited only to security administration personnel through either network segmentation or using the IP access control list restriction feature within PAN-OS. An alternative mitigation includes the use of a Panorama central manager and disabling of http and https management on each of the vulnerable appliance, then use the Panorama context switching feature to remotely access the web interface of the device.
Palo Alto Networks would like to thank Won Lae Lee and Hwang, Gyu Won from Samsung for reporting this issue
