Remediation
Red Hat mitigation
Implementing proper access control on the Beaker cache database, to prevent unauthorized writes into the database, will mitigate exploitation of this flaw. This flaw also cannot be triggered if the Cache functionality of Beaker is not used. When using the Session feature of Beaker, use the signing functionality to verify the integrity of the data retrieved from the database before deserialization.
