: This attempts to prematurely close the original, legitimate SQL query statement intended by the developers [2].
: This is the malicious command. It instructs the database to pause or "sleep" for 5 seconds before responding to the query [2, 3].
If you enter this payload into a form and the website takes roughly 5 seconds longer than usual to load, it confirms that the application is vulnerable to SQL injection [2]. {KEYWORD}');SELECT SLEEP(5)#
This technique is known as [3].
If the payload works, an attacker can replace SLEEP(5) with more complex queries (e.g., IF(SUBSTRING((SELECT password FROM users),1,1)='a', SLEEP(5), 0) ) to extract data character-by-character based on whether the server pauses [3]. Security Implications : This attempts to prematurely close the original,
This string is a classic example of a , specifically targeting databases like MySQL or MariaDB to identify vulnerabilities [1, 2].
Ensure the database user account used by the web application has limited permissions. If you enter this payload into a form
