An attacker could exploit this vulnerability by sending a crafted packet to the IP address of a device that has Web Access enabled. A successful exploit could allow the attacker to access sensitive information from the device.\r\nNote: To exploit this vulnerability, Web Access must be enabled on the phone. Web Access is disabled by default.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200"],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-phone-write-g3kcC5Df"],"products":["cisco:desk_phone_9841_firmware","cisco:desk_phone_9851_firmware","cisco:desk_phone_9861_firmware","cisco:desk_phone_9871_firmware","cisco:ip_phone_7811_firmware","cisco:ip_phone_7821_firmware","cisco:ip_phone_7841_firmware","cisco:ip_phone_7861_firmware","cisco:ip_phone_8811_firmware","cisco:ip_phone_8821_firmware","cisco:ip_phone_8841_firmware","cisco:ip_phone_8845_firmware","cisco:ip_phone_8851_firmware","cisco:ip_phone_8851nr_firmware","cisco:ip_phone_8861_firmware","cisco:ip_phone_8865_firmware","cisco:video_phone_8875_firmware"],"source":"nvd","synced_at":"2026-10-19T22:07:46.309729541+00:00"},"epss":{"cve":"CVE-2025-20336","score":0.00387,"percentile":0.32844,"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).
