Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-404: Improper Resource Shutdown or Release, where the product does not release or incorrectly releases a resource before it is made available for re-use. In Github.com/omec project/amf, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
