Are Your Applications Vulnerable
to Log4j?

A bug in the Log4j library can allow an attacker to execute arbitrary code on systems that use Log4j to write logs.
 

Log4j is an old-timer open-source library used by many software developers and built-in into many Java-based platforms. A common scenario would be to log write the user-agent HTTP header to the log. However, it can be any part of the HTTP request, not only the HTTP protocol.

This security vulnerability affects many applications, some of which you can find in any organization (e.g., 
VMWare, AWS, Google, and many more). However, some may be unique and specific to your organization alone.

The challenge is finding Log4j because of the way Java packaging works. It's possible you have Log4j hiding somewhere in your application and don’t even know about it.

Test if your applications are vulnerable to Log4j

Why is it a challenge to address Log4j?

The Java ecosystem distributes dependencies as Java archive (JAR) files. These files are packages that one can use as a Java library. For example, you can have a JAR nested in a JAR.

 

This situation creates many layers that all need to be investigated. Just looking at the JARs your project draws directly may not be enough, since Log4j could be hiding inside another JAR file!

How Komodo Consulting addresses
Log4j vulnerabilities

Komodo Consulting scans many nested JAR files layers, identify their existence, their version, and report which vulnerabilities your software contains.

We can scan your applications no matter where they reside:

Scan a directory on disk

Scan a container image locally

Scan a container in a remote registry

We recommend scanning source code before or after building the final application. It’s important to scan your applications during every stage of development. A clean source code scan doesn't mean the final build will be. Even scanning after deployment is a good idea. Maybe you didn’t pick up a critical Log4j vulnerability last week, but this week you might!
