Alert ImpactNot Exploitable
Technical DetailsThe flaw exists but it is not exploitable
Technical Details ExplanationRSA has investigated the issue and have deemed that the flaw exists but is not exploitable.
This is because of the following:
  • Access Manager does not accept the input from the user to de-serialize the data.
  • AxM runtime interfaces are not serializing any of the custom Java objects.
  • Most of the references are associated with the Admin API, the methods for which are executed over the authentication.
ResolutionNo changes are required. It is also suggested to run AxM components in SSL auth mode.
