The vulnerability is due to insufficient validation of user-supplied input to the xAPI of the affected software. An attacker could exploit this vulnerability by sending a crafted request to the xAPI. A successful exploit could allow the attacker to read and write arbitrary files in the system. To exploit this vulnerability, an attacker would need either an In-Room Control or administrator account.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","score":7.2},"cwes":["CWE-22"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-telepresence-path-tr-wdrnYEZZ","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-telepresence-path-tr-wdrnYEZZ"],"products":["cisco:ex60_firmware","cisco:ex90_firmware","cisco:sx10_firmware","cisco:sx20_firmware","cisco:sx80_firmware","cisco:telepresence_codec_c40_firmware","cisco:telepresence_codec_c60_firmware","cisco:telepresence_codec_c90_firmware","cisco:telepresence_mx200_firmware","cisco:telepresence_mx300_firmware","cisco:telepresence_mx700_firmware","cisco:telepresence_mx800_firmware","cisco:webex_board_55_firmware","cisco:webex_board_55s_firmware","cisco:webex_board_70_firmware","cisco:webex_board_70s_firmware","cisco:webex_board_85s_firmware","cisco:webex_dx70_firmware","cisco:webex_dx80_firmware","cisco:webex_room_55_firmware","cisco:webex_room_70_firmware"],"source":"nvd","synced_at":"2026-10-19T21:09:53.489947993+00:00"},"epss":{"cve":"CVE-2020-3143","score":0.08453,"percentile":0.95012,"date":"2026-11-01"},"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).
