Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer, where the product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. this may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. 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 flaw has been found in omec-project amf up to 2.1.1. This vulnerability affects unknown code of the component NGAP Message Handler. Executing a manipulation can lead to memory corruption. The attack can be launched remotely. The exploit has been published and may be used. This patch is called 8a4c33cdda866094f1989bdeff6d8642fce8de8435f89defd66831c97715f5aa. It is best practice to apply a patch to resolve this issue.
