"The remote Red Hat Enterprise Linux CoreOS 4 host has a package installed that is affected by a vulnerability as
referenced in the RHSA-2023:1524 advisory.

  - Apache Commons Text performs variable interpolation, allowing properties to be dynamically evaluated and
    expanded. The standard format for interpolation is ${prefix:name}, where prefix is used to locate an
    instance of org.apache.commons.text.lookup.StringLookup that performs the interpolation. Starting with
    version 1.5 and continuing through 1.9, the set of default Lookup instances included interpolators that
    could result in arbitrary code execution or contact with remote servers. These lookups are: - script -
    execute expressions using the JVM script execution engine (javax.script) - dns - resolve dns records -
    url - load values from urls, including from remote servers Applications using the interpolation defaults
    in the affected versions may be vulnerable to remote code execution or unintentional contact with remote
    servers if untrusted configuration values are used. Users are recommended to upgrade to Apache Commons
    Text 1.10.0, which disables the problematic interpolators by default. (CVE-2022-42889)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
