- It was found that when using remote logging with log4j
socket server the log4j server would deserialize any log
event received via TCP or UDP. An attacker could use
this flaw to send a specially crafted log event that,
during deserialization, would execute arbitrary code in
the context of the logger application. (CVE-2017-5645)"
