Unspecified Vulnerability in Phusion Passenger

Phusion Passenger is an Apache module for deploying Ruby on Rails projects on Apache and Nginx web servers from Phusion Netherlands. A security vulnerability exists in the 'switchGroup' function in the agent/ExecHelper/ExecHelperMain.cpp file in Phusion Passenger, which stems from the program...

Privilege Escalation

Passenger is vulnerable to privilege escalations. The application contains a race condition when a file is created, the permission assignment is done with the file path rather than the file descriptor, leading to improper assignments of permissions...

CVE-2018-12615

An issue was discovered in switchGroup in agent/ExecHelper/ExecHelperMain.cpp in Phusion Passenger before 5.3.2. The set of groups gidset is not set correctly, leaving it up to randomness i.e., uninitialized memory which supplementary groups are actually being set while lowering privileges...

Privilege Escalation

Phusion Passenger is vulnerable to privilege escalation. The gidset variable that manages group permissions is not set properly, leaving group permissions to be assigned at random due to a uninitialized buffer...

CVE-2018-12615

Phusion Passenger (before 5.3.2) is affected by CVE-2018-12615. The issue is in switchGroup() (agent/ExecHelper/ExecHelperMain.cpp): the gidset controlling supplementary groups is not set correctly, leaving it up to randomness (uninitialized memory) to determine which groups are actually applied ...

CVE-2018-12027

An Insecure Permissions vulnerability in SpawningKit in Phusion Passenger 5.3.x before 5.3.2 causes information disclosure in the following situation: given a Passenger-spawned application process that reports that it listens on a certain Unix domain socket, if any of the parent directories of sa...

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...
