CVE-2025-65133: School Management System SQLi Vulnerability

CVE-2025-65133 Overview

CVE-2025-65133 is a SQL injection vulnerability in the School Management System version 1.0 by manikandan580. A remote attacker can send a crafted HTTP request to an affected endpoint to manipulate SQL query logic. The flaw allows extraction of sensitive data from the backend database without authentication. The weakness is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact

An unauthenticated attacker can extract sensitive database contents, including student records and credentials, over the network with low attack complexity.

Affected Products

• School Management System version 1.0 by manikandan580
• Web application deployments exposing the vulnerable endpoint
• Backend SQL database accessed by the application

Technical Details for CVE-2025-65133

Vulnerability Analysis

The School Management System 1.0 fails to sanitize user-supplied input before incorporating it into SQL statements. An attacker submits crafted parameters in an HTTP request that break out of the intended query context. The application executes the modified query against the database, returning attacker-controlled results. Exploitation requires no authentication, no user interaction, and can be performed remotely over the network.

Successful exploitation impacts confidentiality, integrity, and availability of the database. Attackers can read arbitrary tables, modify records, or in some configurations execute administrative database operations. The EPSS probability is 0.202% (percentile 42.085) as of 2026-05-14, indicating limited observed exploitation activity at this time.

Root Cause

The root cause is improper neutralization of special characters in SQL query construction [CWE-89]. The application concatenates untrusted HTTP request parameters directly into SQL statements rather than using parameterized queries or prepared statements. Input validation and output encoding routines are absent on the affected endpoint.

Attack Vector

The attack vector is network-based. An attacker sends an HTTP request containing SQL metacharacters and payload fragments to the vulnerable endpoint. The injected fragment alters the WHERE clause, UNION-selects additional columns, or stacks queries depending on the database driver. Refer to the GitHub PoC for CVE-2025-65133 for endpoint and parameter details. No verified code samples are reproduced here.

Detection Methods for CVE-2025-65133

Indicators of Compromise

• HTTP request logs containing SQL metacharacters such as ', ", --, ;, UNION SELECT, or OR 1=1 in query parameters or POST bodies targeting School Management System endpoints.
• Database error messages returned in HTTP responses that disclose SQL syntax, table names, or column names.
• Unusual outbound data volumes from the application server to clients following targeted HTTP requests.
• Application or database logs showing queries with unexpected UNION, INFORMATION_SCHEMA, or SLEEP( calls.

Detection Strategies

• Deploy a web application firewall with SQL injection signature detection on the application's public endpoints.
• Enable database query logging and alert on queries referencing information_schema, mysql.user, or other sensitive system tables.
• Correlate web server access logs with database slow query logs to identify time-based blind injection attempts.
• Run authenticated and unauthenticated dynamic application security testing (DAST) scans against the deployment.

Monitoring Recommendations

• Monitor HTTP 500 responses and database error events tied to user-controllable parameters.
• Track per-source-IP request rates to login, search, and report endpoints for enumeration patterns.
• Alert on database authentication events outside expected application service accounts.
• Forward web, application, and database logs to a centralized SIEM for correlation and retention.

How to Mitigate CVE-2025-65133

Immediate Actions Required

• Remove the School Management System 1.0 instance from public exposure until a fix is in place.
• Restrict access to the application using IP allowlists, VPN, or reverse proxy authentication.
• Rotate database credentials and any application secrets that may have been exposed.
• Audit database tables accessed by the application service account for unauthorized modifications.

Patch Information

No vendor patch is listed in the NVD entry at the time of publication. Review the GitHub Security Advisory for CVE-2025-65133 for the current vendor response status. Operators should track the upstream repository for fixes and rebuild deployments once parameterized queries are introduced.

Workarounds

• Place a web application firewall in front of the application with SQL injection rules enabled in blocking mode.
• Apply least-privilege database permissions so the application account cannot read system tables or write outside required schemas.
• Disable verbose database error messages in HTTP responses to limit information disclosure.
• If source code access is available, refactor vulnerable queries to use prepared statements with bound parameters before redeploying.
