{"id":"CVE-2020-3431","state":"PUBLISHED","title":"Cisco Small Business RV Series Routers Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Small Business RV042 Dual WAN VPN Routers and Cisco Small Business RV042G Dual Gigabit WAN VPN Routers could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.\r\nThe vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected software. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive browser-based information.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.","publishedAt":"2024-11-18T16:02:42.393Z","updatedAt":"2024-11-18T16:32:56.721Z","severity":{"score":6.1,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/RL:X/RC:X/E:X","source":"cisco"},"assigner":"cisco","products":["Cisco Cisco Small Business RV Series Router Firmware"],"affected":[{"vendor":"Cisco","product":"Cisco Small Business RV Series Router Firmware","versions":[{"version":"N/A","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sa-rv-routers-xss-K7Z5U6q3"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T19:47:29.373Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2020/3xxx/CVE-2020-3431.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2020-3431","state":"PUBLISHED","datePublished":"2024-11-18T16:02:42.393Z","dateUpdated":"2024-11-18T16:32:56.721Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2019-12-12T00:00:00.000Z"},"containers":{"cna":{"title":"Cisco Small Business RV Series Routers Cross-Site Scripting Vulnerability","descriptions":[{"lang":"en","value":"A vulnerability in the web-based management interface of Cisco Small Business RV042 Dual WAN VPN Routers and Cisco Small Business RV042G Dual Gigabit WAN VPN Routers could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.\r\nThe vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected software.
