Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Commerce Merchandising accessible data as well as unauthorized read access to a subset of Oracle Commerce Merchandising accessible data. Affects: o Oracle Commerce Merchandising 11.0.0, 11.1,0, 11.2.0, 11.3.0, 11.3.1, 11.3.2 MITIGATION Oracle states: "Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply CPU fixes as soon as possible. Until you apply the CPU fixes, it may be possible to reduce the risk of successful attack by blocking network protocols required by an attack. For attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from users that do not need the privileges may help reduce the risk of successful attack. Both approaches may break application functionality, so Oracle strongly recommends that customers test changes on non-production systems. Neither approach should be considered a long-term solution as neither corrects the underlying problem."
