Log4j issue 101 Image
#Log4J 2.16.0 is out.

Fully disables all JNDI related functionality, and removes the lookups feature.
logging.apache.org/log4j/2.x/chan…
It's also time to use SLF4j so that you can switch logging libraries without any pain, I said this in 2013 though javarevisited.blogspot.com/2013/08/why-us…

With all the chaos going on, I thought to put some important info about Java Log4j issue
1. only version affected between >= 2.0 and <=2.14.1 are affected
2. If your application is not externally exposed, its low risk
3. version 2.15.0 of log4j released without this issue
A 🧵
JDK versions greater than 6u211, 7u201, 8u191, and 11.0.1 are not affected by the LDAP attack vector. In these versions com.sun.jndi.ldap.object.trustURLCodebase is set to false meaning JNDI cannot load remote code using LDAP.
Exploit Requirements
- A server with a vulnerable log4j version (listed above),
- an endpoint with any protocol (HTTP, TCP, etc) that allows an attacker to send the exploit string,
- and a log statement that logs out the string from that request.
