Palo Alto Networks PAN-OS before 3.1.10 and 4.0.x before 4.0.5 allows remote attackers to execute arbitrary commands via unspecified vectors, aka Ref ID 31091.
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
