Unauthenticated command execution via YAML cookie deserialization
Published Oct 6, 2023 · Updated Sep 19, 2024
Command injection in Geokit Rails before 2.5.0 allows remote attackers to execute host commands via a malicious geo_location cookie. The retrieve_location_from_cookie_or_service method passes the untrusted cookie directly to YAML.load and constructs a GeoLoc object from the deserialized result. The Rails application must enable the geocode_ip_address callback and accept the attacker-supplied cookie; commands run with the application process privileges.
