The 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 sending malicious input to the affected software through crafted DHCP requests, and then persuading a user 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.","severity":{"version":"3.0","score":5.2,"vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00432,"percentile":0.37668,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2019-10-16T18:36:28Z","modified":"2026-06-17T02:15:16Z","products":[{"vendor":"cisco","product":"cisco spa122 ata with router"},{"vendor":"cisco","product":"spa122_firmware"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191016-spa-dhcp-xss","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-12703"},{"url":"https://github.com/advisories/GHSA-j3mr-9fcj-h6c6"}],"sources":{"cve":[{"id":"CVE-2019-12703","title":"Cisco SPA122 ATA with Router Devices DHCP Services Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco SPA122 ATA with Router Devices could allow an unauthenticated, adjacent attacker to conduct cross-site scripting attacks.
