Time-based SQL Injection
Description
In a time-based attack, someone could inject a SQL command to the server with code to force a delay in the execution of the queries or with a heavy query that generates this time delay. Depending on the time response, it is possible to deduct some information and determine if a vulnerability is present to exploit it.
Impact
- Allow an attacker to interfere with the queries that an application makes to its database.
- Retrieve information from the database an even extract data.
- Affect the authentication and authorization aspects of the application.
- Steal sensitive information stored in databases.
Recommendation
- Use of prepared statements (with parameterized queries).
- Use of stored procedures.
- Enforcing the least privilege.
Threat
Anonymous attacker from an intranet.
Expected Remediation Time
⌚ minutes.
