CVE-2020-3147

Name of the Vulnerable Software and Affected Versions Cisco Small Business Switches versions prior to 1.3.7.18

Description A vulnerability in the web UI of Cisco Small Business Switches could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper validation of requests sent to the web interface. An attacker could exploit this vulnerability by sending a malicious request to the web interface of an affected device. A successful exploit could allow the attacker to cause an unexpected reload of the device, resulting in a DoS condition.

Recommendations For versions prior to 1.3.7.18, update the firmware to version 1.3.7.18 or later to resolve the issue. As a temporary workaround, consider restricting access to the web interface to minimize the risk of exploitation. Avoid sending malicious requests to the web interface until the issue is resolved.
