Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Deserialization of Untrusted Data

EUVDB-ID: #VU27960

Risk: Medium

CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-17571

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

Exploit availability: No

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 SocketServer class in Log4j. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system,  if these is a deserialization gadget listening to untrusted network traffic for log data.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install update from vendor's website.
