A vulnerability exists in PAN-OS that could lead to rendering the management interface unavailable for legitimate use. (Ref # PAN-78127 / CVE-2017-15942)

Severity: High

PAN-OS contains a vulnerability that may allow a non-authenticated third party to mount a Denial of Service attack against the management interface. Successful exploitation of this issue may allow an attacker to render the PAN-OS management interface unavailable.

Products Affected

Workarounds and Mitigations

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.
