Re: Remote code execution exploit found in Log4j .....

Anyone care to share a real world example of how this would hurt someone on
the IBM i? From what I understand it requires a lot of variables... one
being that the attacker needs to be able to inject commands into the logger.

Not a hypothetical.. real world. Maybe if you found it on your system..
step us through how someone could cause harm without having credentials to
your system.

One thing to keep in mind ... some vendors repackage jar's so their
product is included in a single jar, with all the required classes
included (either as classes or jar's with a special class loader).

This is going to make it very difficult to detect if the vulnerable
classes are used.

This is true. AND sometimes their jars are themselves buried in .war and
.ear files.

PLUG: Us IBM i engineers at Absolute Performance can help with searching
for this stuff, also on Windows, Linux, AIX ...
