CVE-2021-1542
Cisco Small Business 220 Series Smart Switches could allow a remote attacker to gain elevated privileges on the system, caused by the use of weak session management for session identifier values.

CVE-2021-1543
Cisco Small Business 220 Series Smart Switches are vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the web-based management interface. A remote attacker could exploit this vulnerability using a specially-crafted URL to execute script in a victim’s Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim’s cookie-based authentication credentials.
CVE-2021-1571
Cisco Small Business 220 Series Smart Switches are vulnerable to HTML injection. A remote attacker could inject malicious HTML code, which when viewed, would be executed in the victim’s Web browser within the security context of the hosting site.
