Prodapt’s approach for making applications secure Protect your applications with WAF (Web-Application Firewall).A new version (2.16) fixing this issue was released. Log4j has released version 2.15 by partially fixing this vulnerability, but this version can be affected by DoS attacks. Set log4jformatMsgNoLookups to true (Available in version 2.10).Follow this link for regular updates about AWS services How do we fix it? Symantec Endpoint Protection Manager (SEPM)Ī complete list of affected software can be found here: ĪWS is constantly updating their services vulnerable to log4j.
Splunk Enterprise Amazon Machine Image (AMI).The CISA has released the list of software that are impacted by this security flaw. If you use any of the below packages/software/tools and your application is internet-facing, you are more likely to get affected. Should I be worried?Įven though you are not using the log4j library directly in your application, you may be affected. I’m not using the LOG4J library in my application. The JNDI lookup in log4j downloads a java object and executes it in the JVM of your machine. Through this, an attacker can get access to the file system/databases/environment variables and perform any malicious activity.Ī sample request data with user-agent value altered by the attacker that points to an LDAP server to access the crypto mining software. Most of the logging libraries will have access to file system/databases/environment variables to update the logs. which can lead to a serious impact.īy injecting any malicious binary, attackers can get access to all the processes which the log4j can access.
The address can point to a malicious server/download and execute shell script/exe, set up crypto-mining software, etc. If someone sends a request to your application with a malicious website/server address, instead of simply logging the request, log4j will execute the JNDI lookup by resolving the address specified in the request. As a matter of fact, Log4j is JNDI lookup enabled (Java Naming and Directory Service) by default. Say your application is internet-facing and it uses log4j library with JNDI lookup enabled.
RCE is a technique where the attacker can run any commands/code on the victim’s machine. Through Remote Code Execution (RCE), attackers have leveraged a critical zero-day vulnerability in Apache Log4j. Log4j is a java-based logging library that can provide multiple log levels such as FATL, ERROR, INFO, DEBUG, TRACE, etc. Is your application at risk? Let’s find out. Major SIEM & SOAR platforms using the log4j library are also at risk. This serious security flaw has affected every known internet application and, nearly 41% of corporate networks in India are now vulnerable to this security flaw. The first three days of the initial breakout saw over 846,000 attacks globally. The Log4j vulnerability is haunting the internet by increasing its risk to 100 hacks per minute.
