CVE-2018-0407: Cisco sf300-08 firmware cross-site scripting vulnerability

Cisco · Sf300 08 Firmware

A vulnerability in the web-based management interface of Cisco Small Business 300 Series (Sx300) Managed Switches could allow an authenticated, remote attacker to conduct a persistent cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. 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 interface or allow the attacker to access sensitive browser-based information. Cisco Bug IDs: CSCvi87326.
