A Cross-Site Scripting (XSS) vulnerability exists in the PAN-OS URL filtering “continue page” (Ref # PAN-OS 90835, CVE-2018-7636). PAN-OS software does not properly validate specific request parameters.
PAN-OS major release PAN-OS 8.0 is affected (PAN-OS 8.0.10 and earlier). Other PAN-OS major releases are not affected (8.1.x, 7.1.x, 6.1.x).
PAN-OS 8.0.11-h1 and later. PAN-OS major releases 8.1.x, 7.1.x, and 6.1.x are not impacted.
This issue impacts the continue page and admin override page, but does not impact the block page. URL filtering configurations that only use the “block” page but not the continue page or admin override feature are not impacted.
Palo Alto Networks would like to thank Ayushman Dutta for reporting this issue.
