CVE-2019-12718: Cisco sf250-24 firmware cross-site scripting vulnerability

Cisco · Sf250 24 Firmware

A vulnerability in the web-based interface of Cisco Small Business Smart and Managed Switches could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. The vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious link and subsequently access a specific web interface page. 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.
