Description
You can configure Palo Alto Networks firewalls to host a web-based Captive Portal to authenticate users. A denial of service condition was identified in this subsystem (Ref. 92413).
A third party user could remotely disrupt the captive portal’s operation, provoking a delay before it resumes normal operations.
This issue affects PAN-OS 5.0.18 and earlier; PAN-OS 6.0.13 and earlier; PAN-OS 6.1.11 and earlier; PAN-OS 7.0.6 and earlier; PAN-OS 7.1.1 and earlier
