Description
Open5GS through 2.8.0 contains a heap out-of-bounds read vulnerability in ogs_pfcp_parse_dropped_dl_traffic_threshold() that allows remote unauthenticated attackers to read past IE buffers via short IEs. Attackers can send PFCP Session Establishment or Modification Requests to the UPF on UDP port 8805 with DLPA and DLBY flags set, potentially crashing the UPF.
