CWE-1089: Large Data Table with Excessive Number of Indices
Learn about CWE-1089 (Large Data Table with Excessive Number of Indices), its security impact, exploitation methods, and prevention guidelines.
What is Large Data Table with Excessive Number of Indices?
• Overview: Large Data Table with Excessive Number of Indices (CWE-1089) occurs when a software product uses a data table with too many indices, which can degrade performance and potentially lead to vulnerabilities if an attacker can exploit the slowdown.
• Exploitation Methods:
- Attackers can exploit this vulnerability by triggering operations that involve the data table, causing performance degradation.
- Common attack patterns include intentionally generating queries that heavily utilize the indexed columns, leading to resource exhaustion.
• Security Impact:
- Direct consequences of successful exploitation include significant slowdowns in application performance.
- Potential cascading effects may include denial of service if the system becomes too slow to respond to legitimate requests.
- Business impact could involve reduced user satisfaction and potential revenue loss due to degraded service availability.
• Prevention Guidelines:
- Specific code-level fixes include reviewing and reducing the number of indices on large tables where possible, and optimizing query performance.
- Security best practices involve regularly monitoring database performance and reviewing index usage to ensure efficiency.
- Recommended tools and frameworks include database performance monitoring tools and query optimization utilities to help identify and mitigate excessive indices.
