This enables threat actors (who know the machineKey) to serialize a payload for server-side deserialization to achieve remote code execution. NOTE: a CentreStack admin can manually delete the machineKey defined in portal\\web.config.","cvss_version":"3.1","cvss_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","base_score":9.8,"base_severity":"CRITICAL","attack_vector":"NETWORK","privileges_req":"NONE","user_interaction":"NONE","scope":"UNCHANGED","impact_c":"HIGH","impact_i":"HIGH","impact_a":"HIGH","cwe_ids":["CWE-321","CWE-798"],"in_kev":true,"kev_date_added":"2025-04-08","kev_ransomware":false,"epss_score":0.94343,"epss_percentile":0.99851,"cap_rule_version":"0.1.1","stage":"INITIAL_ACCESS","req_access":"NONE","req_vector":"NETWORK","req_user_interaction":false,"grant_access":"USER","caps":["CODE_EXEC","CRED_ACCESS"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-09-18T11:33:15.814784+00:00","first_seen":"2025-04-03T20:15:24.987000+00:00","kev_first_seen":"2025-04-08T00:00:00+00:00","novelty_score":0.0,"novelty_reasons":[],"novelty_at":null,"vendors":["gladinet"],"products":["centrestack"],"affected":[{"vendor":"gladinet","product":"centrestack","ranges":["< 16.4.10315.56368"]}]}
