Improper Input Validation

Overview Affected versions of this package are vulnerable to Improper Input Validation in the ueId validation process in EE subscription handlers. An attacker can cause unauthorized data creation and persistent data corruption by submitting arbitrary identifier values that bypass intended format...

free5GC UDR has improper `ueId` validation in EE subscription handlers that allows arbitrary identifier persistence

Summary The free5GC UDR accepts arbitrary non-3GPP ueId values in the EE subscription creation and query flows because the regular expression used for validation ends with the catch-all alternative |.+. This causes the validation logic to accept any non-empty string rather than restricting input ...
