CVE-2020-1728: Medium severity redhat Keycloak vulnerability
A flaw was found in Keycloak’s Admin Console, where it is missing HTTP security headers in HTTP responses. This issue is not a direct vulnerability and may not lead to a security issue, but increases the chances of allowing attackers to exploit other security flaws. Examples of these possible exploits are servers being prone to clickjacking, channel downgrade attacks, and other similar client-based attack vectors.
Other sources
A vulnerability was found in all versions of Keycloak where, the pages on the Admin Console area of the application are completely missing general HTTP security headers in HTTP-responses. This does not directly lead to a security issue, yet it might aid attackers in their efforts to exploit other problems. The flaws unnecessarily make the servers more prone to Clickjacking, channel downgrade attacks and other similar client-based attack vectors.
