CVE-2020-3162

Name of the Vulnerable Software and Affected Versions Cisco IoT Field Network Director (affected versions not specified)

Description The issue is related to insufficient input validation of incoming CoAP traffic in the Constrained Application Protocol (CoAP) implementation. This could allow a remote attacker to cause a denial of service (DoS) condition on an affected device by sending a specially crafted malicious packet. The attacker could exploit this by sending a malformed CoAP packet to an affected device, potentially forcing the CoAP server to stop and interrupting communication to the IoT endpoints.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
