Everything you need to know

Log4j, a widely-used open-source logging service developed by Apache Software Foundation, came under scrutiny after a series of critical vulnerabilities were publicly revealed in December 2021. The exploits are linked to the Java Naming and Directory Interface (JNDI) and include remote code execution (RCE) flaws. Attackers can exploit these vulnerabilities to inject fraudulent messages, enabling arbitrary code execution and system exploitation. Companies such as Apple and VMware and products like Apache Struts and Minecraft were affected. Cybersecurity agencies advised organizations to implement DevSecOps strategies, use network-based filtering, scan vulnerable applications, patch regularly, and monitor for suspicious traffic to mitigate this risk.
