On December 9, 2021, Apache disclosed CVE-2021-44228 , a remote code execution vulnerability affecting the Apache Log4j2, a Java-based logging framework widely used in commercial and open-source software products.
Vulnerability Details
Apache Log4j2 library is one of the most widely used Java-based logging utilities globally. Due to its widespread use in popular software and hardware platforms, a large number of third-party apps may be vulnerable to exploitation.
• CVE-2021-44228: A vulnerability in versions of Log4j2 prior to 2.15 allowing a malicious actor to access arbitrary resources through an encapsulated Java Naming and Directory Interface (JNDI) request.
• CVE-2021-45046: Similar to CVE-2021-44228 but only affecting Log4j2 version 2.15.0 which allows a malicious actor to launch a denial of service (DOS) attack on the hosting server.
