NVD Description

Note: Versions mentioned in the description apply only to the upstream passenger package and not the passenger package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

In agent/Core/SpawningKit/Spawner.h in Phusion Passenger 5.1.10 (fixed in Passenger Open Source 5.1.11 and Passenger Enterprise 5.1.10), if Passenger is running as root, it is possible to list the contents of arbitrary files on a system by symlinking a file named REVISION from the application root folder to a file of choice and querying passenger-status --show=xml.
