These vulnerabilities are due to insufficient input validation. An attacker could exploit these vulnerabilities by using the web-based management interface to upload a file to location on an affected device that they should not have access to. A successful exploit could allow the attacker to overwrite files on the file system of the affected device.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-22","CWE-36"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-rv160-260-filewrite-7x9mnKjn","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-rv160-260-filewrite-7x9mnKjn"],"products":["cisco:rv160_vpn_router_firmware","cisco:rv160w_wireless-ac_vpn_router_firmware","cisco:rv260_vpn_router_firmware","cisco:rv260p_vpn_router_with_poe_firmware","cisco:rv260w_wireless-ac_vpn_router_firmware"],"source":"nvd","synced_at":"2026-10-19T21:14:10.479542811+00:00"},"epss":{"cve":"CVE-2021-1297","score":0.03734,"percentile":0.89834,"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).
