CVE-2024-4807: College Management System SQLi Vulnerability

CVE-2024-4807 Overview

CVE-2024-4807 is a SQL injection vulnerability in Kashipara College Management System 1.0. The flaw resides in the delete_user.php script, where the id parameter is passed to a database query without proper sanitization. Attackers can manipulate this parameter remotely to inject arbitrary SQL statements. The issue is tracked as VulDB entry VDB-263927 and mapped to CWE-89. Public disclosure includes a proof-of-concept report, increasing the risk of opportunistic exploitation against exposed instances.

Critical Impact
Authenticated remote attackers can inject SQL through the id parameter of delete_user.php, leading to unauthorized read, modification, or deletion of database records.

Technical Details for CVE-2024-4807

Vulnerability Analysis

The vulnerability is a classic SQL injection ([CWE-89]) affecting the user-deletion workflow in Kashipara College Management System 1.0. The delete_user.php endpoint accepts an id argument from the request and concatenates it into an SQL statement without parameterization or type enforcement. Attackers submit crafted values in id to break out of the intended query context and append arbitrary SQL clauses. According to the enriched data, the EPSS probability is 0.803% with a percentile of 53.335, indicating moderate exploitation likelihood relative to peer CVEs. Public proof-of-concept material has been published, lowering the barrier to weaponization.

Root Cause

The root cause is missing input validation and lack of prepared statements in delete_user.php. User-supplied data flows directly into a dynamic SQL query, allowing operator injection. The application does not enforce integer casting on the id parameter or use parameterized queries via PDO or mysqli prepared statements.

Attack Vector

Exploitation occurs over the network against the web interface. The attacker sends an HTTP request to delete_user.php with a manipulated id parameter containing SQL metacharacters such as ', UNION SELECT, or time-based payloads. Because the attack vector is Network with Low attack complexity and requires low-privilege access, any authenticated user with access to the admin functionality can trigger the flaw. Successful injection permits data extraction, tampering, or destructive queries against the backend database.

See the GitHub Vulnerability Report and VulDB #263927 for the disclosed proof-of-concept details.

Detection Methods for CVE-2024-4807

Indicators of Compromise

HTTP requests to /delete_user.php containing SQL metacharacters in the id parameter, such as ', --, UNION, SLEEP(, or OR 1=1.
Unexpected DELETE, SELECT, or UNION-based queries in MySQL general or slow query logs originating from the College Management System database user.
Web server access logs showing repeated requests to delete_user.php from a single source IP with varying id values.

Detection Strategies

Deploy web application firewall rules that inspect the id query parameter for SQL syntax and reject non-numeric input to delete_user.php.
Correlate application logs with database audit logs to identify anomalous queries triggered by user-deletion actions.
Enable database query logging and alert on statements containing UNION SELECT, boolean-based tautologies, or time-delay functions targeting the application schema.

Monitoring Recommendations

Monitor for high volumes of 4xx or 5xx responses from delete_user.php, which often indicate probing.
Track outbound connections and DNS lookups from the database host that could indicate out-of-band SQL injection exfiltration.
Alert on administrative account activity outside normal business hours, especially interactions with user management endpoints.

How to Mitigate CVE-2024-4807

Immediate Actions Required

Restrict access to the College Management System admin interface using network ACLs, VPN, or IP allowlists until a fix is applied.
Audit the database for unauthorized changes to the users table and related records.
Rotate database credentials and application session secrets if exploitation is suspected.
Review web server and database logs from May 2024 forward for indicators listed above.

Patch Information

No official vendor patch is listed in the enriched CVE data or vendor advisories. Organizations running Kashipara College Management System 1.0 should contact the vendor for remediation guidance and consider replacing the affected application if no fix becomes available. Refer to VulDB CTI #263927 for tracking updates.

Workarounds

Modify delete_user.php to cast the id parameter to an integer before use, for example using intval($_GET['id']) in PHP.
Replace dynamic SQL concatenation with parameterized queries using PDO prepared statements or mysqli bound parameters.
Deploy a web application firewall signature to block SQL metacharacters in the id parameter of delete_user.php.
Enforce least-privilege on the database account used by the application so that injection cannot invoke DROP, GRANT, or cross-database queries.

bash

# Example WAF rule (ModSecurity) to block SQLi patterns on delete_user.php
