Two reports to find out where you are using Log4j

A flaw in Apache Log4j allows an attacker to execute arbitrary code by injecting attacker-controlled data into a logged message. Though vScope does not inventory specific files on servers, it can be of great help identifying applications and systems that might be affected by the vulnerability in Log4j (Log4Shell).

Notice To follow this guide, vScope Server module is required

Background

Apache Log4j is a Java-based logging utility and one of the most popular logging libraries used by software developers. On 24 November 2021, exposed a critical vulnerability that allowed potential attackers to execute arbitrary code by injecting attacker-controlled data into a logged message.

The vulnerability has been listed as CVE-2021-44228 on National Vulnerability Database and described in detail on Apache.org.

If you want to know if vScope is affected (it is not), we keep posting updates in a post on our newsfeed.

How vScope can help

Since vScope stores and updates a detailed map of assets in your data center, you can use vScope to quickly get an overview of how you might be affected by the CVE-2021-4428 vulnerability. Here are two easy searches in vScope to help you get started.

Important Notice There is no auto-win here, meaning vScope will not provide you with 100% coverage of all affected applications. There might be false positives. You should use these methods together with recommendations from software suppliers and scanning results from antivirus software.

Shortcut: Search for Log4j

Try search vScope for ‘log4j’ and you will find two reports bundled in vScope.

Looking at running processes

If you are using vScope to inventory Windows OS, you will have access to updated information about processes running on servers (and clients). These processes can give your hints about applications that are using Log4j.

Start by building a table about processes, add columns “Command Line”, “Application”, and “System”. Filtering on “log4j” and/or “JNDI” in the Command Line column will show any processes that might use the Log4j library.

Locating vulnerable applications

vScope keeps track of any applications found in data sources such as Windows/Linux OS SCCM, Jamf, Desktop Central. This means that you can do powerful filters to list any applications, version, vendor, and where it is installed. So, with a relevant list of vulnerable applications, you can quickly find if any application is installed in your environment.

Below is a regex including 280 applications that have been confirmed as affected by CVE-2021-44228. The list has been fetched from Cisagov’s Github. Simply copy and paste the below regex and paste it into the Name -> Match filter in a table about Applications.

Remember: There might be false positives in the resulting table, the application may have been removed from Cisagov’s list of affected applications, or vScope’s discovery might not inventory your complete infrastructure.
