Log4j RCE Found
https://github.com/Glavo/log4j-patch
This is a non-intrusive patch that allows you to block this vulnerability without modifying the program code/updating the dependent. So you can use it to patch third-party programs, such as Minecraft.
The principle of the library is simple: It provides an empty JndiLookup to override the implementation in log4j. Log4j2 can handle this situation and safely disable JNDI lookup.
It is compatible with all versions of log4j2 (2.0~2.15).
