CVE-2014-3514
Description
It was discovered that Active Record's create_with method failed to properly check attributes passed to it. A remote attacker could possibly use this flaw to bypass the strong parameter protection and modify arbitrary model attributes via mass assignment if an application using Active Record called create_with with untrusted values.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Technical Impact: Execute Unauthorized Code or Commands; Alter Execution Logic; Read Application Data; Modify Application Data
If an attacker can provide an untrusted input that contains argument-separating delimiters, then the resulting command will have more arguments than intended by the developer, potentially changing the expected behavior of the command. Depending on the functionality supported by the extraneous arguments, this may have security-relevant consequences. The attacker could include arguments that allow unintended commands or code to be executed, allow sensitive data to be read or modified, or cause other unintended behavior.
