- Issue
- Spring Cloud SSO Connector, version 2.1.2, contains a regression which disables issuer validation in resource servers that are not bound to the SSO service. In PCF deployments with multiple SSO service plans, a remote attacker can authenticate to unbound resource servers which use this version of the SSO Connector with tokens generated from another service plan. Mitigation Users of affected versions should apply the following mitigation: Releases that have fixed this issue include:</p<ul<liSpring Cloud SSO Connector: 2.1.3</li</ul Alternatively, you can perform <uone</u of the following workarounds:</p<ul<liBind your resource server to the SSO service plan via a service instance binding</li<liSet “sso.connector.cloud.available=true” within your Spring application properties</li</ul
Recommended action: Upgrade to 2.1.3.RELEASE or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
