Official description

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain sensitive information and cause a denial of service due to the generation of error messages containing sensitive information.

The underlying weakness: Generation of Error Message Containing Sensitive Information

The product generates an error message that includes sensitive information about its environment, users, or associated data.

How developers prevent this class of flaw

  • Handle exceptions internally and do not display errors containing potentially sensitive information to a user.
  • Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.
  • Debugging information should not make its way into a production release.
