Technical details
A SQL injection vulnerability exists in CodeAstro Simple Online Leave Management System 1.0 within the '/SimpleOnlineLeave/admin/deletemp.php' file. The root cause is the failure to properly validate, sanitize, or parameterize the 'id' GET parameter before using it in a database query. An attacker with network access and low-level privileges (authenticated as an admin or similar) can provide a malicious payload, such as time-based blind SQL injection strings, to extract data or manipulate the database. A public exploit involving the 'SLEEP' function has been disclosed. Remediation requires implementing prepared statements with parameter binding for all user-supplied inputs.
