Summary

AMF Vulnerable to Improper Resource Shutdown or Release

Details

A security flaw has been discovered in omec-project amf up to 2.1.3-dev. The impacted element is the function RANConfiguration of the file ngap/handler.go. The manipulation results in null pointer dereference. The attack may be launched remotely. The exploit has been released to the public and may be used for attacks. Upgrading to version 2.2.0 is sufficient to resolve this issue. Upgrading the affected component is recommended. The same pull request fixes multiple security issues.
