CWE-1067: Excessive Execution of Sequential Searches of Data Resource
Learn about CWE-1067 (Excessive Execution of Sequential Searches of Data Resource), its security impact, exploitation methods, and prevention guidelines.
What is Excessive Execution of Sequential Searches of Data Resource?
• Overview: Excessive Execution of Sequential Searches of Data Resource, identified as CWE-1067, occurs when a product executes a data query against an SQL table or view without using an index, leading to inefficient sequential searches that degrade performance.
• Exploitation Methods:
- Attackers can exploit this vulnerability by repeatedly querying the database, knowing that each request results in a full table scan, which can lead to system slowdowns or unavailability.
- Common attack patterns include Denial-of-Service (DoS) attacks, where the attacker intentionally overloads the system to degrade its performance or make it inaccessible.
• Security Impact:
- Direct consequences include significant slowdowns in data retrieval, increasing response times and reducing system efficiency.
- Potential cascading effects include overall system performance degradation, making it susceptible to further performance-related vulnerabilities.
- Business impact can be severe, leading to downtime, loss of customer trust, and potential financial losses due to reduced service availability.
• Prevention Guidelines:
- Specific code-level fixes include ensuring that database queries are optimized with appropriate indexing strategies to avoid full table scans.
- Security best practices involve regular performance testing and database query optimization to identify and mitigate inefficient searches.
- Recommended tools and frameworks include database query analyzers and performance monitoring tools to detect and address indexing issues proactively.
