Summary
o 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.
There are no workarounds that address this vulnerability.
