A vulnerability exists in the Management Web Interface that could allow for Information Disclosure. The Management Web Interface does not properly validate specific request parameters which can potentially allow for Information Disclosure. (Ref # PAN-70434 / CVE-2017-7216)
Successfully exploiting this issue would require an attacker to be authenticated.
PAN-OS 7.1.8 and earlier

Palo Alto Networks recommends to implement best practice by allowing web interface access only to a dedicated management network. Additionally, restrict the set of IP addresses to a subset of authorized sources that you allow to interact with the management network.
Palo Alto Networks would like to thank Christophe Schleypen from NATO Communications and Information Agency for reporting this issue to us.
