commons_configuration

Apache Commons Configuration 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.configuration2.interpol.Lookup that performs the interpolation. Starting with version 2.4 and continuing through 2.7, 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 Configuration 2.8.0, which disables the problematic interpolators by default.

Out-of-bounds Write vulnerability in Apache Commons Configuration.This issue affects Apache Commons Configuration: from 2.0 before 2.10.1. Users are recommended to upgrade to version 2.10.1, which fixes the issue.

Uncontrolled Resource Consumption vulnerability in Apache Commons Configuration 1.x. There are a number of issues in Apache Commons Configuration 1.x that allow excessive resource consumption when loading untrusted configurations or using unexpected usage patterns. The Apache Commons Configuration team does not intend to fix these issues in 1.x. Apache Commons Configuration 1.x is still safe to use in scenario's where you only load trusted configurations. Users that load untrusted configurations or give attackers control over usage patterns are recommended to upgrade to the 2.x version line, which fixes these issues. Apache Commons Configuration 2.x is not a drop-in replacement, but as it uses a separate Maven groupId and Java package namespace they can be loaded side-by-side, making it possible to do a gradual migration.
