Outdated log4j library used

[prodigysml]

Just wanted to raise that this tool is using an outdated log4j library: https://github.com/nccgroup/CollaboratorPlusPlus/blob/d36dd9f12624ee8ec3bfcb5f462bfc484cd2bdd3/build.gradle#L29

The tool is an awesome tool and I'm aware of multiple people using it, so figured it might be a good idea to try get fixed. Upgrading to version 2.17.0 should fix the issue. It is possibly exploitable if the debug mode is enabled: https://github.com/nccgroup/CollaboratorPlusPlus/blob/29e05c3f0815ee3dd21cf29be3120c6d8166e488/src/main/java/com/nccgroup/collaboratorplusplus/server/HttpHandler.java#L71
