{"cve":"CVE-2021-1287","nvd":{"published":"2021-03-18T19:15:13.323","modified":"2026-06-17T03:31:24.837","status":"Modified","description":"A vulnerability in the web-based management interface of Cisco RV132W ADSL2+ Wireless-N VPN Routers and Cisco RV134W VDSL2 Wireless-AC VPN Routers could allow an authenticated, remote attacker to execute arbitrary code on an affected device or cause the device to restart unexpectedly. The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a denial of service (DoS) condition on the affected device.","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-121"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-rv-132w134w-overflow-Pptt4H2p","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-rv-132w134w-overflow-Pptt4H2p"],"products":["cisco:rv132w_firmware","cisco:rv134w_firmware"],"source":"nvd","synced_at":"2026-10-19T21:15:50.279857260+00:00"},"epss":{"cve":"CVE-2021-1287","score":0.02278,"percentile":0.83119,"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).
