SQL Injection Authentication Bypass in CodeAstro Simple Attendance Management System v1.0
CVE-2026-37749 is a SQL injection vulnerability in CodeAstro Simple Attendance Management System v1.0. The flaw is present in index.php and is exploitable through the username parameter. According to the provided information, a remote unauthenticated attacker can supply crafted SQL input to the username parameter and bypass the application's authentication mechanism.
What it means and what to do now: patch path, interim mitigations, and the assume-compromise checklist.
What an attacker gets, and what they’ve been doing with it.
Successful exploitation allows an unauthenticated remote attacker to bypass authentication. The provided CVSS v3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) indicates potential high impact to confidentiality, integrity, and availability.
If you can’t patch tonight, do this now.
If no patch is available, restrict network exposure to the application, especially public access to the login interface. Deploy WAF rules or equivalent filtering to detect and block SQL injection payloads targeting the username parameter in index.php. Monitor authentication logs and web server logs for anomalous login attempts and SQL injection indicators. As a defense-in-depth measure, ensure the backend database account used by the application has least-privilege permissions.
Patch, then assume compromise.
Upgrade to a fixed version if one is made available by the vendor. Review and correct the vulnerable SQL query handling in index.php, specifically the processing of the username parameter. Use parameterized queries or prepared statements, enforce strict server-side input validation, and avoid constructing SQL statements with unsanitized user-controlled input.
