CVE-2024-4803 Overview
CVE-2024-4803 is a SQL injection vulnerability in Kashipara College Management System 1.0. The flaw resides in the submit_admin.php script, where the phone parameter is passed to a database query without proper sanitization. Attackers can manipulate the phone argument to inject arbitrary SQL statements. The vulnerability is remotely exploitable and requires low-level privileges. Public disclosure of the exploit details has occurred through VulDB entry VDB-263923, increasing exposure to opportunistic attackers targeting educational management platforms.
Critical Impact
Remote attackers can inject SQL statements through the phone parameter in submit_admin.php, potentially reading, modifying, or deleting database records containing student, staff, and administrative data.

Technical Details for CVE-2024-4803
Vulnerability Analysis
The vulnerability is classified under CWE-89, Improper Neutralization of Special Elements used in an SQL Command. The submit_admin.php endpoint accepts a phone parameter and concatenates the value directly into a backend SQL query. Attackers submit crafted input containing SQL metacharacters to alter query logic. Successful exploitation allows extraction of database contents, authentication bypass through boolean-based injection, and modification of stored records. The affected component handles administrative submission workflows, making it a valuable target for attackers seeking privileged access to college management data.
Root Cause
The root cause is missing input validation and the absence of parameterized queries in submit_admin.php. User-supplied data in the phone field is trusted and interpolated directly into SQL statements. The application does not apply prepared statements, escaping, or type enforcement before query execution.
Attack Vector
Exploitation occurs over the network without user interaction. An attacker sends an HTTP request to submit_admin.php with a malicious phone payload. Since the endpoint requires only low privileges, any authenticated user of the college management portal can trigger the flaw. Public proof-of-concept material referenced in the GitHub CVE Hub Document demonstrates the injection pattern against the vulnerable parameter.
No verified code examples are available. The exploitation pattern involves appending SQL clauses such as UNION SELECT or boolean tautologies to the phone field, causing the backend MySQL engine to return attacker-controlled result sets. Refer to the VulDB entry #263923 for additional technical context.
Detection Methods for CVE-2024-4803
Indicators of Compromise
- HTTP POST requests to submit_admin.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or OR 1=1 in the phone field
- Web server logs showing unusually long or encoded phone parameter values inconsistent with phone number formats
- Database error messages returned to clients or logged during processing of admin submissions
- Unexpected outbound queries or bulk record enumeration originating from the college management application account
Detection Strategies
- Deploy web application firewall (WAF) signatures targeting SQL injection patterns on the submit_admin.php endpoint
- Enable database query logging and alert on syntactically anomalous queries originating from the application service account
- Correlate authentication events with immediate access to submit_admin.php to identify attacker reconnaissance
Monitoring Recommendations
- Monitor web server access logs for repeated requests to submit_admin.php from single source IP addresses
- Track database response times and row-count anomalies indicative of UNION-based extraction
- Alert on any modification of administrative tables outside expected business workflows
How to Mitigate CVE-2024-4803
Immediate Actions Required
- Restrict network access to the college management portal to trusted IP ranges until a vendor patch is available
- Deploy WAF rules blocking SQL injection payloads directed at submit_admin.php, particularly targeting the phone parameter
- Audit database accounts used by the application and remove unnecessary privileges such as FILE, DROP, or cross-database access
- Review web and database logs for evidence of prior exploitation attempts referencing the vulnerable parameter
Patch Information
No vendor advisory or official patch has been published for Kashipara College Management System 1.0. Organizations running this software should evaluate migration to a supported alternative or apply code-level remediation by rewriting submit_admin.php to use parameterized queries. Track updates through the VulDB CTI record #263923 and the VulDB submission tracker.
Workarounds
- Replace direct SQL concatenation in submit_admin.php with prepared statements using PDO or mysqli parameter binding
- Apply server-side input validation enforcing numeric-only content and length limits on the phone field
- Place the application behind an authenticating reverse proxy to reduce exposure of the vulnerable endpoint
