CVE-2011-0448 describes a SQL Injection vulnerability discovered in Ruby on Rails versions 3.0.x prior to 3.0.4. This flaw allows attackers to manipulate SQL queries by providing non-integer values to the limit function, potentially leading to unauthorized data access or modification. The vulnerability was publicly disclosed in 2017 and a patch is available in version 3.0.4.
Successful exploitation of CVE-2011-0448 could allow an attacker to bypass application security controls and directly interact with the underlying database. This could result in the unauthorized retrieval, modification, or deletion of sensitive data, including user credentials, financial information, or application configuration details. Depending on the database schema and application logic, an attacker might also be able to execute arbitrary commands on the database server, potentially leading to a complete compromise of the system. The impact is amplified in environments where the application handles sensitive data or is integrated with other critical systems.
CVE-2011-0448 has been publicly disclosed and a proof-of-concept may be available. While active exploitation is not widely reported, the vulnerability's ease of exploitation and the potential impact make it a persistent risk. It was added to the NVD database on 2017-10-24. The vulnerability's age means that many applications may still be running vulnerable versions, making it a target for opportunistic attackers.

The primary mitigation for CVE-2011-0448 is to upgrade to Ruby on Rails version 3.0.4 or later. If upgrading is not immediately feasible, consider implementing input validation on the limit function to ensure that only integer values are accepted. While not a complete solution, this can reduce the attack surface. Web application firewalls (WAFs) configured to detect and block SQL injection attempts can also provide a layer of defense. Thoroughly review and sanitize all user inputs to prevent malicious code from reaching the database.
