  • What's new in Java 18 for us, developers ?

    The guys at Oracle have made this point on this forum quite often, but it never really hit home for me personally until the recent log4j vulnerability made me more interested in the topic and the available mitigation options (see https://github.com/gredler/aegis4j/).

    If you've been impacted by these log4j vulnerabilities, have a look at aegis4j, a Java agent that completely disables platform features you don't use, before an attacker uses them against you (including e.g. JNDI and Java serialization).

    Yep, this is why strategically patching InitialContext when the class is initially loaded will completely disable JNDI (and mitigate future JNDI-based exploits).

  • Log4j 2.15.0 – Previously suggested mitigations may not be enough

    The recent log4j vulnerability really piqued my interest, and I've spent the last few evenings working on a proof of concept Java agent that could mitigate similar vulnerabilities in the future, for applications that are able to completely forego platform features like JNDI, serialization or native process execution.

    It's not a lot of code, but it uses parts of the platform that I think are a bit unusual for most devs, so it was quite interesting to implement. Happy to discuss details, ideas, and concerns.

    One idea for a possible improvement is to make the feature block list adaptive, i.e. watch what the application uses in the first few minutes of execution, and then shut down all unused "dangerous" features for the remaining lifetime of the VM. Not sure how reliable this would be though, especially for services which have background jobs that might only run once a day.
