1) Deserialization of Untrusted Data
EUVDB-ID: #VU19391
Risk: High

CVE-ID: CVE-2019-0192
CWE-ID:
CWE-502 - Deserialization of Untrusted Data
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data within the RMI server component. A remote non-authenticated attacker can configure the JMX server via an HTTP POST request to the Config API, make it point to a malicious RMI server and then execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationInstall updates from vendor's website.
