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.
