{"id":"CVE-2025-1925","url":"https://www.cyber-defence.io/tools/cve/CVE-2025-1925","generatedAt":"2026-10-28T02:12:55.100Z","title":"A vulnerability classified as problematic was found in Open5GS up to 2.7.2.","description":"A vulnerability classified as problematic was found in Open5GS up to 2.7.2. Affected by this vulnerability is the function amf_nsmf_pdusession_handle_update_sm_context of the file src/amf/nsmf-handler.c of the component AMF. The manipulation leads to denial of service. The attack can be launched remotely. This vulnerability allows a single UE to crash the AMF, resulting in the complete loss of mobility and session management services and causing a network-wide outage. All registered UEs will lose connectivity, and new registrations will be blocked until the AMF is restarted, leading to a high availability impact. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue.","published":"2025-03-04T14:15:37.000Z","lastModified":"2026-06-17T08:40:21.000Z","status":"Analyzed","sourceIdentifier":"cna@vuldb.com","cvss":{"version":"4.0","score":6.9,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-404"],"affected":["open5gs/open5gs"],"epss":{"score":0.00831,"percentile":0.57318,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.83%).
