CVE-2025-0843: Needyamin Library Card System SQL Injection

CVE-2025-0843 is a critical SQL injection vulnerability in Needyamin Library Card System affecting the Admin Panel. Attackers can exploit email and password parameters remotely. This article covers technical details, affected versions, impact, and mitigation strategies.

CVE-2025-0843 Overview

A critical SQL injection vulnerability has been identified in needyamin Library Card System version 1.0. The vulnerability exists in the Admin Panel's authentication mechanism, specifically within the admindashboard.php file. Through manipulation of the email and password parameters, an unauthenticated attacker can inject malicious SQL statements to bypass authentication, extract sensitive data, or potentially compromise the underlying database system.

Critical Impact

This SQL injection vulnerability allows remote attackers to bypass admin authentication and potentially gain unauthorized access to the Library Card System's administrative functions and underlying database.

Affected Products

  • needyamin Library Card System 1.0
  • Admin Panel component (admindashboard.php)
  • Systems using vulnerable email/password authentication flow

Technical Details for CVE-2025-0843

Vulnerability Analysis

This vulnerability is classified as SQL Injection (CWE-89) with a related classification of Injection (CWE-74). The flaw exists in the authentication handling logic within the admindashboard.php file of the Admin Panel component. When processing login requests, the application fails to properly sanitize user-supplied input in the email and password parameters before incorporating them into SQL queries. This allows an attacker to craft malicious input that alters the intended SQL query structure, potentially bypassing authentication controls entirely or extracting sensitive information from the database.

The network-accessible attack vector means any remote attacker with HTTP access to the admin panel can attempt exploitation without requiring any prior authentication or special privileges. The exploit has been publicly disclosed, increasing the risk of widespread exploitation attempts against vulnerable installations.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries or prepared statements in the authentication mechanism. The application directly concatenates user-supplied input from the email and password form fields into SQL query strings without sanitization or escaping. This classic SQL injection pattern allows attackers to manipulate query logic by injecting SQL metacharacters and syntax.

Attack Vector

The attack is network-based and targets the Admin Panel login functionality. An attacker sends a crafted HTTP request to admindashboard.php with malicious SQL syntax embedded in the email or password parameters. Common attack patterns include:

  • Authentication bypass using tautology-based injections (e.g., ' OR '1'='1)
  • UNION-based attacks to extract data from other database tables
  • Time-based blind SQL injection to enumerate database contents
  • Stacked queries (if supported) to execute additional SQL statements

The vulnerability requires no user interaction and can be exploited remotely by any attacker with network access to the vulnerable endpoint. For technical analysis and additional details, refer to the Web Security Insights Analysis which documents the admin login bypass technique.

Detection Methods for CVE-2025-0843

Indicators of Compromise

  • Unusual login attempts to admindashboard.php containing SQL metacharacters such as single quotes, double dashes, or UNION keywords
  • Web server access logs showing requests with encoded SQL injection payloads in POST parameters
  • Database query logs containing malformed or unexpected SQL syntax in authentication queries
  • Successful admin logins from unexpected IP addresses or geographic locations

Detection Strategies

  • Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in the email and password parameters
  • Enable detailed logging on the web server and database to capture suspicious query patterns
  • Implement intrusion detection signatures that alert on SQL injection attempt patterns targeting PHP login forms
  • Monitor for anomalous authentication success rates or failed login spikes that may indicate active exploitation attempts

Monitoring Recommendations

  • Configure real-time alerting for any requests to admindashboard.php containing SQL injection indicators
  • Establish baseline metrics for admin authentication patterns and alert on deviations
  • Implement database activity monitoring to detect unauthorized data access or extraction
  • Review access logs regularly for patterns consistent with automated SQL injection scanning tools

How to Mitigate CVE-2025-0843

Immediate Actions Required

  • Restrict network access to the Admin Panel to trusted IP addresses only using firewall rules or .htaccess configuration
  • Deploy a Web Application Firewall (WAF) with SQL injection protection rules as an immediate defensive layer
  • Consider taking the vulnerable application offline until a proper fix can be implemented
  • Audit database and admin accounts for signs of compromise and reset credentials if necessary

Patch Information

As of the last modification date (2025-02-04), no official vendor patch has been released for this vulnerability. Organizations using the affected Library Card System should contact the vendor for remediation guidance or implement defensive mitigations. For additional vulnerability details, refer to the VulDB entry #294000.

Workarounds

  • Implement prepared statements and parameterized queries in the authentication code to prevent SQL injection
  • Apply strict input validation to reject any non-alphanumeric characters in email fields and restrict password field input
  • Deploy network-level access controls to limit Admin Panel access to internal networks or VPN-connected users only
  • Consider using a reverse proxy with request filtering capabilities to sanitize input before it reaches the application
bash
# Example Apache .htaccess configuration to restrict admin panel access
<Files "admindashboard.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Files>
