CVE-2017-5645 – log4j: Socket receiver deserialization vulnerability

https://notcve.org/view.php?id=CVE-2017-5645

In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code. En Apache Log4j 2.x en versiones anteriores a 2.8.2, cuando se utiliza el servidor de socket TCP o el servidor de socket UDP para recibir sucesos de registro serializados de otra aplicación, puede enviarse una carga binaria especialmente diseñada que, cuando se deserializa, puede ejecutar código arbitrario. 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. • https://github.com/pimps/CVE-2017-5645 http://www.openwall.com/lists/oss-security/2019/12/19/2 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/97702 http://www.securitytracker.com/id/1040200 http://www.securit • CWE-502: Deserialization of Untrusted Data •
