An attacker could exploit this vulnerability by sending a crafted HTTP request and reading the file that contains the DCA password from that affected system. A successful exploit could allow the attacker to access another affected system and gain DCA user privileges.\r\nNote: Cisco Catalyst SD-WAN Manager releases 20.18 and later are not affected by this vulnerability.","cvss_version":"3.1","cvss_vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","base_score":7.5,"base_severity":"HIGH","attack_vector":"LOCAL","privileges_req":"HIGH","user_interaction":"NONE","scope":"CHANGED","impact_c":"HIGH","impact_i":"HIGH","impact_a":"HIGH","cwe_ids":["CWE-257"],"in_kev":true,"kev_date_added":"2026-04-20","kev_ransomware":false,"epss_score":0.07317,"epss_percentile":0.94382,"cap_rule_version":"0.1.1","stage":"PRIV_ESC","req_access":"PRIV","req_vector":"LOCAL","req_user_interaction":false,"grant_access":"PRIV","caps":["CODE_EXEC","PRIV_GAIN"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-09-18T11:58:25.536451+00:00","first_seen":"2026-02-25T17:25:30.150000+00:00","kev_first_seen":"2026-04-20T00:00:00+00:00","novelty_score":0.0,"novelty_reasons":[],"novelty_at":null,"vendors":["cisco"],"products":["catalyst_sd-wan_manager"],"affected":[{"vendor":"cisco","product":"catalyst_sd-wan_manager","ranges":["< 20.9.8.2","≥ 20.10 and < 20.12.5.3","≥ 20.13 and < 20.15.4.2","≥ 20.16 and < 20.18","20.12.6"]}]}
