CVE-2019-17571 is an unsafe deserialization vulnerability in the SocketServer class of Apache Log4j 1.2, affecting releases through 1.2.17. SocketServer accepts serialized log events and deserializes them without enforcing an allowlist of permitted object types. An attacker can supply a malicious serialized object that invokes a suitable deserialization gadget chain during object reconstruction, resulting in arbitrary code execution. This issue is distinct from CVE-2017-5645, which affects analogous socket-server functionality in Log4j 2.x.
