An attacker could exploit this vulnerability by persuading an authenticated user of the interface to follow a crafted link. A successful exploit could allow the attacker to perform a factory reset of the affected device, resulting in a Denial of Service (DoS) condition.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-352"],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipphone-csrf-HOCmXW2c","https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipphone-csrf-HOCmXW2c"],"products":["cisco:ip_conference_phone_7832_with_multiplatform_firmware","cisco:ip_conference_phone_8831_with_multiplatform_firmware","cisco:ip_conference_phone_8832_with_multiplatform_firmware","cisco:ip_phone_6821_with_multiplatform_firmware","cisco:ip_phone_6825_with_multiplatform_firmware","cisco:ip_phone_6841_with_multiplatform_firmware","cisco:ip_phone_6851_with_multiplatform_firmware","cisco:ip_phone_6861_with_multiplatform_firmware","cisco:ip_phone_6871_with_multiplatform_firmware","cisco:ip_phone_7811_with_multiplatform_firmware","cisco:ip_phone_7821_with_multiplatform_firmware","cisco:ip_phone_7841_with_multiplatform_firmware","cisco:ip_phone_7861_with_multiplatform_firmware","cisco:ip_phone_8800_key_expansion_module_with_multiplatform_firmware","cisco:ip_phone_8811_with_multiplatform_firmware","cisco:ip_phone_8841_with_multiplatform_firmware","cisco:ip_phone_8845_with_multiplatform_firmware","cisco:ip_phone_8851_key_expansion_module_with_multiplatform_firmware","cisco:ip_phone_8851_with_multiplatform_firmware","cisco:ip_phone_8861_key_expansion_module_with_multiplatform_firmware","cisco:ip_phone_8861_with_multiplatform_firmware","cisco:ip_phone_8865_with_multiplatform_firmware","cisco:video_phone_8875_firmware"],"source":"nvd","synced_at":"2026-10-19T21:39:14.809778102+00:00"},"epss":{"cve":"CVE-2023-20221","score":0.00325,"percentile":0.25612,"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).
