Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- log4j-patch: Parche no intrusivo para la vulnerabilidad RCE de #log4j2 🛠
-
Warning for people playing on Minecraft servers. This is important!
There is also log4j-patch which might allow you to resolve issues with it.

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).

How do I construct a curl command for a log4shell ldap server?
I'm using this: https://github.com/mbechler/marshalsec as an LDAP server.

A Study Notes of Exploit Spring Boot Actuator
According to the introduction in https://github.com/mbechler/marshalsec/blob/master/marshalsec.pdf, in addition to the javax.script.ScriptEngineManager class , we can also use the com.sun.rowset.JdbcRowSetImplclass to complete the exploitation through JNDI injection. The payload is as follows

Log4Shell log4j vulnerability (CVE-2021-44228) - cheat-sheet reference guide
Not sure if that method actually works since LDAP is a different protocol than HTTP? If you're running an HTTP server as the receiver, then your server is just going to be confused by the connection and it might not log anything. You either want to run an LDAP server like https://github.com/mbechler/marshalsec , or have some logging method that triggers on any TCP connection, or use a service like dnslog.cn that can log for you. (although I've seen a lot of companies are now specifically blocking that domain which seems silly).
