Description

An information exposure through log file vulnerability exists in the Palo Alto
Networks Prisma Cloud Compute Console where a secret used to authorize the role
of the authenticated user is logged to a debug log file.

Authenticated Operator role and Auditor role users with access to the debug log
files can use this secret to gain Administrator role access for their active
session in Prisma Cloud Compute.

Prisma Cloud Compute SaaS versions were automatically upgraded to the fixed
release.

This issue impacts all Prisma Cloud Compute versions earlier than Prisma Cloud
Compute 21.04.412.

Solution

This issue is fixed in Prisma Cloud Compute 21.04.412 and all later versions.

Workarounds and Mitigations

Cloud Compute Console until Prisma Cloud Compute is upgraded to a fixed
version.
