CVE-2022-42889: Apache Commons Text prior to 1.10.0 allows RCE when applied to untrusted input due to insecure interpolation defaults

["Gary D. Gregory" <ggregory () apache org>]

Severity: important

Description:

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.

Mitigation:

Upgrade to Apache Commons Text 1.10.0.
