Error description

  • Multiple vulnerabilities have been reported for log4j-1.x. These
    vulnerabilities have been assessed as not applicable in the
    context of IBM Business Automation Workflow, IBM Business
    Process Manager. The Apache foundation stopped supporting
    log4j-1.x several years ago. There is a latent risk of new
    vulnerabilities being reported for log4j-1.x and no expectation
    of fixes by the Open Source community. As a matter of
    precaution, log4j-1.x is removed or upgraded where possible.
    
    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:
