CVE-2018-12026

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...

CVE-2018-12028

An Incorrect Access Control vulnerability in SpawningKit in Phusion Passenger 5.3.x before 5.3.2 allows a Passenger-managed malicious application, upon spawning a child process, to report an arbitrary different PID back to Passenger's process manager. If the malicious application then generates a...

CVE-2018-12029

A race condition in the nginx module in Phusion Passenger 3.x through 5.x before 5.3.2 allows local escalation of privileges when a non-standard passengerinstanceregistrydir with insufficiently strict permissions is configured. Replacing a file with a symlink after the file was created, but befor...

Denial Of Service (DoS)

passenger is vulnerable to denial of service DoS attacks. A malicious user can create a child process that reports an arbitrary PID to Passenger's process manager, which can be terminated if the malicious process generates an error...

Information Disclosure

passenger is vulnerable to information disclosure attacks. The vulnerability exists through an insecure permissions vulnerability where a normal user of the UNIX system could swap the application's user directory to redirect traffic to a non-application user's process through an alternative UNIX...
