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.
Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
