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.\n\n\n\n\n\nReleases 1.11.0 and 2.0.0-M2 address a potential security issue when accessing enum properties in an uncontrolled way. If an application using Commons BeanUtils passes property paths from an external source directly to the getProperty() method of PropertyUtilsBean, an attacker can access the enum\u2019s class loader via the \u201cdeclaredClass\u201d property available on all Java \u201cenum\u201d objects. Accessing the enum\u2019s \u201cdeclaredClass\u201d allows remote attackers to access the ClassLoader and execute arbitrary code. The same issue exists with PropertyUtilsBean.getNestedProperty().\nStarting in versions 1.11.0 and 2.0.0-M2 a special BeanIntrospector suppresses the \u201cdeclaredClass\u201d property. Note that this new BeanIntrospector is enabled by default, but you can disable it to regain the old behavior; see section 2.5 of the user's guide and the unit tests.\n\nThis issue affects Apache Commons BeanUtils 1.x before 1.11.0, and 2.x before 2.0.0-M2.Users of the artifact commons-beanutils:commons-beanutils\n\n 1.x are recommended to upgrade to version 1.11.0, which fixes the issue.\n\n\nUsers of the artifact org.apache.commons:commons-beanutils2\n\n 2.x are recommended to upgrade to version 2.0.0-M2, which fixes the issue."}, {"lang": "es", "value": "Vulnerabilidad de control de acceso inadecuado en Apache Commons. Se a\u00f1adi\u00f3 una clase especial BeanIntrospector en la versi\u00f3n 1.9.2. Esta permite impedir que los atacantes utilicen la propiedad de clase declarada de los objetos de enumeraci\u00f3n de Java para acceder al cargador de clases. Sin embargo, esta protecci\u00f3n no estaba habilitada por defecto. PropertyUtilsBean (y, en consecuencia, BeanUtilsBean) ahora impide el acceso a las propiedades de clase declaradas por defecto. Las versiones 1.11.0 y 2.0.0-M2 solucionan un posible problema de seguridad al acceder a las propiedades de enumeraci\u00f3n de forma incontrolada. Si una aplicaci\u00f3n que utiliza Commons BeanUtils pasa rutas de propiedades desde una fuente externa directamente al m\u00e9todo getProperty() de PropertyUtilsBean, un atacante puede acceder al cargador de clases de la enumeraci\u00f3n mediante la propiedad \"declaredClass\", disponible en todos los objetos \"enum\" de Java. Acceder a la propiedad \"declaredClass\" de la enumeraci\u00f3n permite a atacantes remotos acceder al cargador de clases y ejecutar c\u00f3digo arbitrario. El mismo problema existe con PropertyUtilsBean.getNestedProperty(). A partir de las versiones 1.11.0 y 2.0.0-M2, un BeanIntrospector especial suprime la propiedad \"declaredClass\". Tenga en cuenta que este nuevo BeanIntrospector est\u00e1 habilitado por defecto, pero puede deshabilitarlo para recuperar el comportamiento anterior; consulte la secci\u00f3n 2.5 de la gu\u00eda del usuario y las pruebas unitarias. Este problema afecta a Apache Commons BeanUtils 1.x anterior a la 1.11.0 y a las versiones 2.x anterior a la 2.0.0-M2. Se recomienda a los usuarios del artefacto commons-beanutils:commons-beanutils 1.x actualizar a la versi\u00f3n 1.11.0, que soluciona el problema. Se recomienda a los usuarios del artefacto org.apache.commons:commons-beanutils2 2.x actualizar a la versi\u00f3n 2.0.0-M2, que soluciona el problema."}], "lastModified": "2025-06-09T18:56:26.370", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:apache:commons_beanutils:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "3ABE6272-1A82-437E-8153-DE129760FD51", "versionEndExcluding": "1.11.0", "versionStartIncluding": "1.0"}, {"criteria": "cpe:2.3:a:apache:commons_beanutils:2.0.0:milestone1:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D211BECE-15F4-4685-8B8C-BB6221A2CC83"}], "operator": "OR"}]}], "sourceIdentifier": "security@apache.org"}
