This vulnerability exists because the GUI is accessible on self-managed cloud installations or local server installations of Cisco vManage. An attacker could exploit this vulnerability by accessing the exposed GUI of Cisco SD-AVC. A successful exploit could allow the attacker to view managed device names, SD-AVC logs, and SD-AVC DNS server IP addresses.","severity":{"version":"3.1","score":5.3,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00922,"percentile":0.60585,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-798"],"published":"2022-09-30T18:45:49Z","modified":"2026-06-17T04:25:14Z","products":[{"vendor":"cisco","product":"cisco sd-wan vmanage"},{"vendor":"cisco","product":"sd-wan"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdavc-ZA5fpXX2","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-20844"},{"url":"https://github.com/advisories/GHSA-mvqp-5v99-c8gp"}],"sources":{"cve":[{"id":"CVE-2022-20844","title":"Cisco Software-Defined Application Visibility and Control on Cisco vManage Static Username and Password Vulnerability","description":"A vulnerability in authentication mechanism of Cisco Software-Defined Application Visibility and Control (SD-AVC) on Cisco vManage could allow an unauthenticated, remote attacker to access the GUI of Cisco SD-AVC using a default static username and password combination.
