Descriptions

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The XWiki Crypto API will generate X509 certificates signed by default using SHA1 with RSA, which is not considered safe anymore for use in certificate signatures, due to the risk of collisions with SHA1. The problem has been patched in XWiki version 13.10.6, 14.3.1 and 14.4-rc-1. Since then, the Crypto API will generate X509 certificates signed by default using SHA256 with RSA. Administrators are advised to upgrade their XWiki installation to one of the patched versions. If the upgrade is not possible, it is possible to patch the module xwiki-platform-crypto in a local installation by applying the change exposed in 26728f3 and re-compiling the module.

La API Crypto de XWiki generará certificados X509 firmados por defecto usando SHA1 con RSA, que ya no es considerada segura para su uso en firmas de certificados, debido al riesgo de colisiones con SHA1. El problema ha sido parcheado en versiones 13.10.6, 14.3.1 y 14.4-rc-1 de XWiki. Desde entonces, la Crypto API generará certificados X509 firmados por defecto usando SHA256 con RSA. Es recomendado a administradores que actualicen su instalación de XWiki a una de las versiones parcheadas. Si la actualización no es posible, es posible parchear el módulo xwiki-platform-crypto en una instalación local al aplicar el cambio expuesto en 26728f3 y volviendo a compilar el módulo
