Sourcecodester Basic Library System v1.0 is vulnerable to SQL Injection in /librarysystem/load_admin.php.
AnalysisAI
SQL injection in Sourcecodester Basic Library System v1.0 allows high-privilege authenticated attackers to extract sensitive data via the /librarysystem/load_admin.php endpoint. The vulnerability requires administrative authentication, limiting exposure to compromised or malicious admin accounts. EPSS exploitation probability is minimal at 0.02% (6th percentile), and no public exploit code has been identified, making this a low-priority issue despite the SQL injection vector.
Technical ContextAI
The vulnerability resides in a PHP-based library management application where user-supplied input is not properly sanitized before being used in SQL queries. CWE-89 (SQL Injection) indicates that the load_admin.php script likely concatenates user input directly into SQL query strings without parameterized prepared statements or input validation. This is a classic PHP vulnerability pattern common in older or poorly-maintained applications that predate modern frameworks with built-in ORM protection. The attack surface is limited by network accessibility and the requirement for valid administrative credentials.
RemediationAI
Apply vendor patches immediately if available, or upgrade to a patched version of Sourcecodester Basic Library System beyond v1.0. Primary mitigation is to implement parameterized prepared statements in /librarysystem/load_admin.php using PHP PDO or mysqli with bound parameters, replacing any SQL string concatenation. If patching is delayed, implement Web Application Firewall (WAF) rules to block SQL injection payloads (single quotes, UNION, SELECT keywords in admin endpoints) and restrict administrative endpoint access to trusted IP ranges. Review VulDB (https://vuldb.com/vuln/357129) and NIST NVD (https://nvd.nist.gov/vuln/detail/CVE-2026-36873) for vendor-specific patches, though given the legacy nature of this application, source code review and custom remediation may be necessary.
