    "In Log4j <= 2.14, `Message Lookups` were enabled by default creating an input validation vulnerability.\n",
    "A threat actor could take advantage of this vulnerability to make a Java application process JNDI lookups to download and execute Java objects from an attacker controlled naming service.\n",
    "There are a few types of Java objects that can be stored in a directory service.\n",
    "A JNDI reference object is one of them. A JNDI reference jave object points to the location of the Java object requested. \n"
