CVE-2019-12703: Cisco SPA122 Firmware

Medium severity, CVSS 5.2. EPSS: 0.4% chance of exploitation in the next 30 days.

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. 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.

Affected products

• Cisco SPA122 Firmware: before 1.4.1 (fixed in 1.4.1); version 1.4.1 only
