Technical details
A SQL injection vulnerability exists in CodeAstro Simple Online Leave Management System 1.0 within the '/SimpleOnlineLeave/index.php' file. The root cause is the failure to sanitize or validate the 'email' POST parameter before using it in a database query. An unauthenticated remote attacker can provide malicious SQL payloads (including boolean-based blind, error-based, and time-based blind techniques) to manipulate backend queries. This can result in unauthorized database access, data exfiltration, or full system compromise. A public exploit (PoC) using sqlmap has been disclosed. No official patch is currently documented, but the issue can be mitigated by using prepared statements with parameterized queries.
