Security Bulletin
Summary
A vulnerability in Apache Log4j could allow an attacker to execute arbitrary code on the system. This vulnerability may affect IBM Spectrum Scale due to its use of Log4j for logging.
Vulnerability Details
CVEID: CVE-2021-4104
DESCRIPTION: Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by the deserialization of untrusted data when the attacker has write access to the Log4j configuration. If the deployed application is configured to use JMSAppender, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/215048 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)
