Summary

Multiple vulnerabilities in Cisco DNA Spaces Connector could allow an authenticated, remote attacker to perform a command injection attack on an affected device. These vulnerabilities are due to insufficient input sanitization when executing affected commands. A high-privileged attacker could exploit these vulnerabilities on a Cisco DNA Spaces Connector by injecting crafted input during command execution. A successful exploit could allow the attacker to execute arbitrary commands as root within the Connector docker container.
