Descriptions

The Plugins Manager in Jenkins before 1.640 and LTS before 1.625.2 does not verify checksums for plugin files referenced in update site data, which makes it easier for man-in-the-middle attackers to execute arbitrary code via a crafted plugin.

The Plugins Manager in Jenkins en versiones anteriores a 1.640 y LTS en versiones anteriores a 1.625.2 no verifica sumas de comprobación para archivos de plugin referenciados en datos del sitio de actualización, lo que facilita a atacantes man-in-the-middle ejecutar código arbitrario a través de un plugin manipulado.
