This clearly illustrates Hybris installations may be vulnerable to Log4j exploit.Till there is proper advisory from SAP Hybris there are couple of workarounds which might be done to mitigate this vulnerability.
Putting in Firewall rules to block the JNDI request might be a good way to prevent this and along with blocking the outbound requests also.
Another way is to put in a System property like this or change the environment variable as shown below
LOG4J_FORMAT_MSG_NO_LOOKUPS to true
