CVE-2026-37749 -- CVSS 9.8 Vulnerability Briefing

CVE-2026-37749 | CVSS 9.8 (Critical) | Exploit: No known exploit

What Is It

A SQL injection vulnerability in CodeAstro Simple Attendance Management System v1.0 allows remote unauthenticated attackers to bypass authentication through the username parameter in the application's login page (index.php).

Technical Detail

The flaw exists in the application's failure to properly sanitize or parameterize user-supplied input in the username field processed by index.php, enabling an attacker to inject arbitrary SQL statements into the backend database query. By crafting a malicious username value, a remote unauthenticated attacker can manipulate the authentication logic to bypass login controls entirely, gaining unauthorized access to the application. Depending on database configuration and privilege levels, further exploitation could extend to data exfiltration, data manipulation, or escalation of access within the application.

Exploitation Status

No known exploit code has been publicly observed or confirmed at this time. The vulnerability is not currently listed in the CISA Known Exploited Vulnerabilities catalog. Despite the absence of confirmed exploitation, the straightforward nature of SQL injection authentication bypass vulnerabilities means the barrier to exploitation is low for any attacker with basic knowledge of SQL injection techniques.

Who Is Targeting This

No specific threat actor attribution at this time. No campaigns or targeted sectors have been identified in connection with this vulnerability. Given the product's likely deployment in educational institutions and small organizations managing attendance records, opportunistic attackers scanning for unpatched web applications represent the most probable threat profile.

What To Do

Organizations running CodeAstro Simple Attendance Management System v1.0 should treat this as a high-priority remediation given the critical CVSS score of 9.8 and the unauthenticated attack vector. Check with the vendor for an updated release that addresses this input validation flaw. If no patch is available, restrict access to the application to trusted networks or authenticated proxies as an interim control. Implement a web application firewall rule to detect and block SQL injection patterns targeting the username parameter in index.php. Review application logs for anomalous login attempts containing SQL metacharacters such as single quotes, comment sequences, or boolean logic strings, which may indicate active probing or exploitation attempts.
