Script Summary

Detects Ruby on Rails servers vulnerable to object injection, remote command executions and denial of service attacks. (CVE-2013-0156)

All Ruby on Rails versions before 2.3.15, 3.0.x before 3.0.19, 3.1.x before 3.1.10, and 3.2.x before 3.2.11 are vulnerable. This script sends 3 harmless YAML payloads to detect vulnerable installations. If the malformed object receives a status 500 response, the server is processing YAML objects and therefore is likely vulnerable.
