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.","published":"2026-02-25T17:25:30.000Z","lastModified":"2026-06-17T10:17:11.000Z","status":"Analyzed","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H"},"cwe":["CWE-257"],"affected":["cisco/catalyst sd-wan manager"],"epss":{"score":0.07317,"percentile":0.9434,"date":"2026-10-26","history":[]},"kev":{"listed":true,"dateAdded":"2026-04-20","dueDate":"2026-04-23","knownRansomwareCampaignUse":"Unknown","notes":"Please adhere to CISA’s guidelines to assess exposure and mitigate risks associated with Cisco SD-WAN devices as outlines in CISA’s Emergency Directive 26-03 (URL listed below in Notes) and CISA’s “Hunt & Hardening Guidance for Cisco SD-WAN Devices (URL listed below in Notes).
