| VCID-a91w-ppku-ebfc | Information Exposure Given a Passenger-spawned application process that reports that it listens on a certain Unix domain socket, if any of the parent directories of said socket are writable by a normal user that is not the application's user, then that non-application user can swap that directory with something else, resulting in traffic being redirected to a non-application user's process through an alternative Unix domain socket. |
CVE-2018-12027
GHSA-whfx-877c-5p28 |
| VCID-e99s-zs31-c3cn | Concurrent Execution using Shared Resource with Improper Synchronization (Race Condition) A race condition in the nginx module in Phusion Passenger allows local escalation of privileges when a non-standard `passenger_instance_registry_dir` with insufficiently strict permissions is configured. Replacing a file with a symlink after the file was created, but before it was chowned, leads to the target of the link being chowned via the path. Targeting sensitive files such as root's crontab file allows privilege escalation. |
CVE-2018-12029
GHSA-jjcj-fgfm-9g9r |
| VCID-etvv-bvc3-qyan | Improper Link Resolution Before File Access During the spawning of a malicious Passenger-managed application, SpawningKit in Phusion Passenger 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. |
CVE-2018-12026
GHSA-7cv3-gvmc-8mq5 |
| VCID-xn3j-fysa-ybga | Incorrect Permission Assignment for Critical Resource An Incorrect Access Control vulnerability in SpawningKit in Phusion Passenger 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 an error, it would cause Passenger's process manager to kill said reported arbitrary PID. |
CVE-2018-12028
GHSA-jjhj-8gx7-x836 |
| VCID-z5g4-xxf6-vbbh | Incorrect Permission Assignment for Critical Resource An issue was discovered in Phusion Passenger. 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. |
