CVE-2021-3509

A flaw was found in the Red Hat Ceph Storage Dashboard. In response to CVE-2020-27839, the JWT token was moved from localStorage to an httpOnly cookie. However, token cookies are used in the body of the HTTP response for the documentation, which again makes it available to XSS. The greatest threat to the system is for confidentiality, integrity, and availability.

Red Hat OpenStack Platform deployments use the ceph package directly from the Ceph channel; the RHOSP package will not be updated at this time. Red Hat OpenShift Container Storage (RHOCS) 4 shipped ceph package for the usage of RHOCS 4.2 only which has reached End of Life. The shipped version of ceph package is neither used nor supported with the release of RHOCS 4.3.

Red Hat Ceph Storage (RHCS) 4 ships a version of ceph which has not been patched for CVE-2020-27839, and therefore, although not vulnerable to this specific flaw, would be vulnerable if CVE-2020-27839 were to be patched without recognition of the flaw.

Red Hat Enterprise Linux 8 is not affected by this flaw as it does not include the ceph dashboard component.
