Exposure of Sensitive Information to an Unauthorized Actor
The Authlogic gem for Ruby on Rails, when used with certain versions before 3.3.0, makes potentially unsafe "find_by_id" method calls, which might allow remote attackers to conduct CVE-2012-6496 SQL injection attacks via a crafted parameter in environments that have a known "secret_token" value, as demonstrated by a value contained in "secret_token.rb" in an open-source product.
CWE-200 - Information Exposure
An information exposure vulnerability is categorized as an information flow (IF) weakness, which can potentially allow unauthorized access to otherwise classified information in the application, such as confidential personal information (demographics, financials, health records, etc.), business secrets, and the application's internal environment.
