CVE-2011-2930 describes multiple SQL injection vulnerabilities within the ActiveRecord adapters of Ruby on Rails. These flaws arise from improper handling of column names within the quotetablename method, allowing attackers to inject malicious SQL code. This can lead to unauthorized data access, modification, or deletion. The vulnerability impacts versions of Ruby on Rails prior to 2.3.13, 3.0.x before 3.0.10, and 3.1.x before 3.1.0.rc5, and a fix is available in the specified patched versions.
Successful exploitation of CVE-2011-2930 allows an attacker to inject arbitrary SQL commands into database queries. This can result in a wide range of malicious activities, including the extraction of sensitive data such as user credentials, financial information, and personally identifiable information (PII). Attackers could also modify or delete data, potentially disrupting application functionality or causing data loss. The blast radius extends to any data accessible through the affected database. While no direct precedent is explicitly cited, the potential for data exfiltration and manipulation mirrors the impact of other SQL injection vulnerabilities, highlighting the critical need for remediation.
CVE-2011-2930 was published in 2017, though the vulnerability itself dates back to earlier versions of Ruby on Rails. It is not currently listed on the CISA KEV catalog. Public proof-of-concept exploits are available, indicating a moderate risk of exploitation. The vulnerability's age and the availability of exploits suggest that it remains a potential target for attackers, particularly those targeting legacy Ruby on Rails applications.
Applications built using older versions of Ruby on Rails (prior to 2.3.13, 3.0.10, or 3.1.0.rc5) are at risk. This includes legacy applications that have not been regularly updated and those deployed in shared hosting environments where the underlying Ruby on Rails framework is managed by the hosting provider. Applications that rely on user-supplied input to construct database queries are particularly vulnerable.
• ruby/server: Inspect application logs for suspicious SQL queries containing unusual characters or keywords (e.g., UNION, SELECT, DROP).
grep -i 'union|select|drop' /var/log/rails/production.log• ruby/server: Use a static analysis tool to scan Ruby code for potential SQL injection vulnerabilities in ActiveRecord queries. • generic web: Monitor web application firewall (WAF) logs for SQL injection attempts targeting Rails endpoints. • generic web: Review access logs for unusual patterns of requests that might indicate an attacker probing for vulnerabilities.

The primary mitigation for CVE-2011-2930 is to upgrade to a patched version of Ruby on Rails, specifically version 2.3.13 or later. If upgrading is not immediately feasible due to compatibility issues or application downtime concerns, consider implementing temporary workarounds. Input validation and sanitization techniques can help prevent malicious column names from reaching the database. Web application firewalls (WAFs) configured to detect and block SQL injection attempts can provide an additional layer of defense. Monitor database logs for suspicious SQL queries that might indicate an attempted exploitation. After upgrading, confirm the fix by attempting to inject a simple SQL statement through a vulnerable parameter and verifying that it is properly sanitized.

CVE-2011-2930 is a SQL injection vulnerability in Ruby on Rails ActiveRecord adapters, allowing attackers to execute arbitrary SQL commands via crafted column names in vulnerable versions.
You are affected if you are using Ruby on Rails versions 2.3.9.pre and below, 3.0.x before 3.0.10, or 3.1.x before 3.1.0.rc5.
Upgrade to a patched version of Ruby on Rails: 2.3.13 or later, 3.0.10 or later, or 3.1.0.rc5 or later. Implement input validation as a temporary workaround.
While no active campaigns are definitively linked, SQL injection vulnerabilities are a persistent threat, and public exploits exist.
