The CVE-2021-44228, also known as "Log4j 2 Remote Code Execution Vulnerability," is a critical security flaw in the popular Java logging library called Log4j 2. This vulnerability allows an attacker to execute arbitrary code on a remote server by sending a specially crafted logging request. The flaw is due to the lack of proper input validation in the JNDI (Java Naming and Directory Interface) lookup feature of Log4j 2.
The flaw was reported on December 9, 2021, and the maintainers of Log4j 2 released a patch on December 14, 2021. However, due to the widespread use of Log4j 2 in various applications and services, the vulnerability has been exploited in the wild, leading to a series of cyberattacks.
To mitigate the risk of exploitation, it is highly recommended to apply the available patch as soon as possible. If it is not feasible to apply the patch immediately, developers should restrict the use of Log4j 2 to a limited set of services and applications, and should avoid using JNDI lookups until a more permanent solution is in place.
In summary, CVE-2021-44228 is a critical security flaw in Log4j 2 that allows remote code execution on a remote server. It is essential to apply the available patch as soon as possible to mitigate the risk of exploitation.Recommended mitigation
The provided answer does not contain any information about a mitigation for the specified CVE (Common Vulnerability Exposure). A mitigation is a strategy to reduce or eliminate the risk associated with a vulnerability. In this case, I would recommend searching for more information about the CVE and its associated vulnerability, as well as any available mitigations. You can typically find this information on the official CVE database or security bulletins from the software vendor.
