Security Advisory

This security advisory describes one high risk vulnerability.

1) Deserialization of Untrusted Data

Severity: High

CVSSv3: 9.1 [CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:F/RL:O/RC:C] [PCI]

CVE-ID: CVE-2019-0192

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Description

The 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.

Mitigation

Install updates from vendor's website.
