CVE-2026-10111: Student Management System SQLi Vulnerability

CVE-2026-10111 Overview

CVE-2026-10111 is a SQL injection vulnerability in sambitraj STUDENT-MANAGEMENT-SYSTEM version 1.0. The flaw resides in the application's Login Page, where the email parameter is passed unsanitized into a backend SQL query. Attackers can manipulate this argument remotely without authentication to alter query logic and access or modify database contents. The issue is categorized under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). A public exploit has been disclosed, and the project maintainer was notified through an issue report but has not responded.

Critical Impact
Remote, unauthenticated attackers can inject SQL through the login form's email parameter, potentially exposing credentials and student records stored in the backend database.

Technical Details for CVE-2026-10111

Vulnerability Analysis

The vulnerability exists in the authentication flow of STUDENT-MANAGEMENT-SYSTEM 1.0. The Login Page accepts an email value from the client and incorporates it into a SQL statement without parameterization or input neutralization. An attacker can submit crafted SQL syntax inside the email field to break out of the intended query context. This enables boolean-based, error-based, or union-based injection techniques to extract data from the backend database. Because the endpoint is reachable pre-authentication, the attacker requires no valid credentials or prior access. Public exploit details have been released, lowering the skill barrier for opportunistic abuse.

Root Cause

The root cause is improper neutralization of user-supplied input before it is concatenated into a SQL query [CWE-74]. The login handler does not use prepared statements or parameterized queries, and it does not validate or escape the email parameter. As a result, SQL metacharacters in the input alter the structure of the executed query.

Attack Vector

The attack vector is network-based and unauthenticated. An attacker submits a malicious payload in the email field of the Login Page through a standard HTTP POST request. By injecting comment sequences and tautologies into the parameter, the attacker can bypass authentication or enumerate database tables and columns. No user interaction is required, and the vulnerability can be triggered from any system that can reach the login endpoint.

No verified exploit code is available; refer to the VulDB vulnerability details and the GitHub issue tracker for further technical context.

Detection Methods for CVE-2026-10111

Indicators of Compromise

HTTP POST requests to the Login Page containing SQL metacharacters such as ', --, #, UNION, OR 1=1, or SLEEP( in the email parameter.
Unusual login failures followed by successful authentications from the same source address within a short interval.
Database error messages returned in HTTP responses originating from the login endpoint.

Detection Strategies

Inspect web server and application logs for request bodies in which the email field contains non-email characters or SQL syntax.
Deploy Web Application Firewall (WAF) rules tuned for SQL injection patterns on the login route.
Enable database query auditing to capture anomalous statements such as UNION SELECT, time-delay functions, or stacked queries originating from the login handler.

Monitoring Recommendations

Monitor authentication endpoints for spikes in request volume and malformed inputs.
Alert on outbound connections from the application server that follow suspicious login activity, which can indicate post-exploitation data exfiltration.
Correlate database error rates with HTTP request patterns to identify probing attempts.

How to Mitigate CVE-2026-10111

Immediate Actions Required

Remove the affected STUDENT-MANAGEMENT-SYSTEM 1.0 deployment from any internet-exposed network segment until a fix is applied.
Rotate any credentials, session tokens, and database secrets that may have been accessible through the vulnerable database.
Review database and web server logs for prior indications of SQL injection attempts against the login endpoint.

Patch Information

No official patch is available. According to the disclosure, the project maintainer was notified via the GitHub Issue Tracker but has not responded. Organizations using this codebase should apply source-level fixes by replacing string-concatenated SQL with parameterized queries or prepared statements, and by enforcing strict input validation on the email field.

Workarounds

Place the application behind a Web Application Firewall configured with SQL injection signatures for the login endpoint.
Restrict access to the Login Page using IP allowlisting or VPN-only access while a code-level fix is developed.
Apply least-privilege controls to the database user the application connects with, removing rights such as FILE, DROP, and access to unrelated schemas.

bash

# Configuration example: minimal WAF rule concept for the email parameter
# (Pseudocode - adapt to your WAF syntax)
SecRule ARGS:email "@rx (['\"]|--|#|\b(UNION|SELECT|OR|AND)\b\s+\d)" \
