This vulnerability is due to a lack of proper input sanitization while querying the external authentication server. An attacker could exploit this vulnerability by sending a crafted query through an external authentication web page. A successful exploit could allow the attacker to gain access to sensitive information, including user credentials from the external authentication server. To exploit this vulnerability, an attacker would need valid operator-level (or higher) credentials.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7},"cwes":["CWE-200","CWE-497"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esasma-info-dsc-Q9tLuOvM","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esasma-info-dsc-Q9tLuOvM"],"products":["cisco:email_security_appliance","cisco:secure_email_and_web_manager"],"source":"nvd","synced_at":"2026-10-19T21:32:39.174919249+00:00"},"epss":{"cve":"CVE-2022-20664","score":0.01034,"percentile":0.63848,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
