Description

A JNDI Injection vulnerability exists in Apache Log4j version 2.0-beta9 to 2.15.0, excluding 2.12.2. The vulnerability is due to improper handling of logged messages when the logging configuration uses a non-default Pattern Layout. An attacker who can control an item in the MapMessage or StrucutredDataMessage can exploit this vulnerability by sending a crafted message to be logged by the target application, a remote unauthenticated attacker can cause denial of service or in certain configuration execute arbitrary code on the target system. This vulnerability is due to the incomplete fix for CVE-2021-44228. *NOTE: This strike uses the local hostname check bypass method.
