3DescriptionCVE.org
A security flaw has been discovered in Open5GS up to 2.7.6. This vulnerability affects the function ogs_gtp2_parse_tft in the library lib/gtp/v2/types.c of the component SMF. Performing a manipulation of the argument pf[0].content.length results in denial of service. The attack is possible to be carried out remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Open5GS versions up to 2.7.6 are vulnerable to a denial of service attack in the SMF component's TFT parsing function when a crafted packet manipulates the traffic filter content length parameter. An unauthenticated remote attacker can trigger this flaw to crash the service, and public exploit code exists with no patch currently available.
