The Log4j component (also known as Log4Shell and LogJam) is a Java-based logging package used by developers to log errors. At the moment, it is already known that the CVE-2021-44228 vulnerability affected a large number of software, including some services of the largest tech companies such as Amazon, Apple, Cisco, Google, Microsoft, Steam and IBM. The Dutch Cybersecurity Center has created a regularly updated doc on GitHub listing the affected applications.
With Total Network Inventory you can quickly build reports on software found on your network from the listed publishers for further analysis. We have also prepared a report with filters for publishers that are currently flagged in the document as vulnerable, patched, or if the status is unknown.
The table report template can be downloaded from here.
