High severity with no evidence of exploitation so far.

What to do

  1. Check which version of Experion Server you run against the affected versions below, and install the vendor's latest release.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

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.
