Who should care

Security teams and administrators of the affected application should be aware of this vulnerability and take necessary actions to mitigate it.

Technical summary

This allows any authenticated user to read and write comments on any process across all business units by supplying an arbitrary object GUID.

Defensive priority

HIGH

Recommended defensive actions

  • Apply patches or updates provided by the vendor to fix the IDOR vulnerability.
