SQL Injection: Auth Bypass
Drill authentication-bypass SQL injection by matching the payload to the query context.
A login form builds SQL unsafely. Discover the parameter shape, adapt for quoted strings or numeric fields, comment out trailing checks, and authenticate as admin.
Variants change the vulnerable field and query tail so the solution is not a single payload pasted into every form.
How the attack works
- Probe the login fields with a single quote to confirm the input reaches the query unsafely.
username: admin' - Work out the query shape — quoted string vs numeric — from how it breaks.
- Inject a tautology and comment out the password check to authenticate as the first user.
username: admin' OR 1=1 -- - - Land in the admin session and read the flag.
