Descriptions

During the spawning of a malicious Passenger-managed application, SpawningKit in Phusion Passenger 5.3.x before 5.3.2 allows such applications to replace key files or directories in the spawning communication directory with symlinks. This then could result in arbitrary reads and writes, which in turn can result in information disclosure and privilege escalation.

Durante la generación de una aplicación maliciosa gestionada por Passenger, SpawningKit en Phusion Passenger en versiones 5.3.x anteriores a la 5.3.2 permite que tales aplicaciones reemplacen archivos o directorios claves en el directorio spawning communication con vínculos simbólicos. Esto podría resultar en lecturas y escrituras arbitrarias, que en cambio podrían resultar en una revelación de información y un escalado de privilegios.

Multiple vulnerabilities have been found in Passenger, the worst of which could result in the execution of arbitrary code. Versions less than 5.3.2 are affected.
