Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

Updated 25.06.2020

Added fixed version for vulnerabilities #1-4

1) Deserialization of Untrusted Data

EUVDB-ID: #VU29131

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2020-14061

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 related to oracle.jms.AQjmsQueueConnectionFactory, oracle.jms.AQjmsXATopicConnectionFactory, oracle.jms.AQjmsTopicConnectionFactory, oracle.jms.AQjmsXAQueueConnectionFactory, and oracle.jms.AQjmsXAConnectionFactory (aka weblogic/oracle-aqjms). A remote attacker can pass specially crafted data to the application and 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.
