A local privilege escalation vulnerability exists in the PAN-OS management web interface that allows the administrator to access the password hashes of local users by manipulating the HTML markup. (Ref. # PAN-91564; CVE-2018-9334)
Successful exploitation of this issue requires the attacker to be authenticated.
PAN-OS 6.1.20 and earlier, PAN-OS 7.1.16 and earlier, PAN-OS 8.0.8 and earlier, and PAN-OS 8.1.0
PAN-OS 6.1.21 and later, PAN-OS 7.1.17 and later, PAN-OS 8.0.9 and later, and PAN-OS 8.1.1 and later
This issue affects the web-based management interface of PAN-OS and is strongly mitigated by following best practices for securing the management interface of PAN-OS. Our best practices guidelines reduce the exposure of the management interface to potential attackers. Please review the Best Practices for Securing Administrative Access in the PAN-OS technical documentation, available at: https://www.paloaltonetworks.com/documentation/80/pan-os/pan-os/getting-started/best-practices-for-securing-administrative-access.
Palo Alto Networks would like to thank Bill Chaison from GCI Inc. for reporting this issue.
