Generation of Error Message Containing Sensitive Information

CVE-2025-69253

Severity Medium
Score 6.6/10

Summary

free5GC is an open-source project for 5th generation (5G) mobile core networks. Versions through 1.4.1 of the User Data Repository are affected by Improper Error Handling with Information Exposure. The NEF component reliably leaks internal parsing error details (e.g., invalid character 'n' after top-level value) to remote clients, which can aid attackers in service fingerprinting. All deployments of free5GC using the "Nnef_PfdManagement" service may be vulnerable. free5gc/udr pull request 56 contains a patch. No direct workaround is available at the application level. Applying the official patch is recommended.
