The vulnerability is due to improper boundary restrictions on user-supplied input in the Guest user feature of the web-based management interface. An attacker could exploit this vulnerability by sending malicious requests to a targeted device, triggering a buffer overflow condition. A successful exploit could allow the attacker to cause the device to stop responding, resulting in a denial of service condition, or could allow the attacker to execute arbitrary code.","severity":{"version":"3.0","score":8.1,"vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","level":"high","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-08","score":0.06765,"percentile":0.94021,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-119"],"published":"2018-10-05T14:00:00Z","modified":"2026-06-17T01:30:45Z","products":[{"vendor":"cisco","product":"cisco rv130w wireless-n multifunction vpn router firmware"},{"vendor":"cisco","product":"rv110w_firmware"},{"vendor":"cisco","product":"rv130w_firmware"},{"vendor":"cisco","product":"rv215w_firmware"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180905-rv-routers-overflow","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"http://www.securityfocus.com/bid/105285","tags":["vdb-entry","x_refsource_BID","x_transferred","Third Party Advisory","VDB Entry"]},{"url":"http://www.securitytracker.com/id/1041675","tags":["vdb-entry","x_refsource_SECTRACK","x_transferred","Third Party Advisory","VDB Entry"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2018-0423"},{"url":"https://github.com/advisories/GHSA-3r77-vxv8-f245"}],"sources":{"cve":[{"id":"CVE-2018-0423","title":"Cisco RV110W, RV130W, and RV215W Routers Management Interface Buffer Overflow Vulnerability","description":"A vulnerability in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router, and Cisco RV215W Wireless-N VPN Router could allow an unauthenticated, remote attacker to cause a denial of service condition or to execute arbitrary code.
