Preface
A recently discovered vulnerability with the Apache Commons Text was reported to Apache. Apache Commons Text performs variable interpolation, allowing properties to be dynamically evaluated and expanded.
These lookups and their actions are:
- script: execute expressions using the JVM script execution engine (javax.script)
- dns: resolve dns records
- url: load values from urls
The url lookup includes values from remote servers Applications, which can allows for remote code execution or unintentional contact with remote servers if untrusted configuration values are used.
