Commons-BeanUtils: Arbitary Code Execution — GLSA 202601-05

A vulnerability has been discovered in Commons-BeanUtils, which can lead to execution of arbitrary code.

Affected packages

Package dev-java/commons-beanutils on all architectures
Affected versions < 1.11.0
Unaffected versions >= 1.11.0

Background

Commons-beanutils provides easy-to-use wrappers around Reflection and Introspection APIs

Description

Multiple vulnerabilities have been discovered in Commons-BeanUtils. Please review the CVE identifiers referenced below for details.

Impact

A special BeanIntrospector class was added in version 1.9.2. This can be used to stop attackers from using the declared class property of Java enum objects to get access to the classloader. However this protection was not enabled by default. PropertyUtilsBean (and consequently BeanUtilsBean) now disallows declared class level property access by default.

Workaround

There is no known workaround at this time.

Resolution

All Commons-BeanUtils users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-java/commons-beanutils-1.11.0"
