CVE-2024-7069: Employee Gate Pass Logging System SQLi

CVE-2024-7069 Overview

CVE-2024-7069 is a SQL injection vulnerability affecting SourceCodester Employee and Visitor Gate Pass Logging System 1.0, developed by oretnom23. The flaw resides in the /employee_gatepass/classes/Master.php?f=delete_department endpoint, where the id parameter is passed to a backend SQL statement without proper sanitization. A remote attacker with low privileges can inject arbitrary SQL through this parameter over the network. The issue is tracked as VulDB entry VDB-272351 and has been publicly disclosed, meaning exploitation details are already available to attackers. The vulnerability maps to [CWE-89] Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact
Authenticated remote attackers can manipulate the id argument in Master.php?f=delete_department to execute arbitrary SQL, potentially altering or exposing records in the underlying database.

Technical Details for CVE-2024-7069

Vulnerability Analysis

The vulnerability is a classic SQL injection reachable through the department deletion handler in Master.php. When a request is made to /employee_gatepass/classes/Master.php?f=delete_department, the application takes the id argument from the client and concatenates it into a DELETE SQL statement without prepared statements or input validation. An attacker can therefore terminate the intended statement and append their own SQL clauses. Because the vulnerable action is invoked over HTTP with only low-level authentication requirements, exploitation can be automated at scale against exposed instances. Public disclosure of the issue on VulDB (VDB-272351) and a GitHub write-up increase the likelihood that opportunistic scanners will target it.

Root Cause

The root cause is missing parameterization in the delete_department action of classes/Master.php. User-controlled input from the id request parameter flows directly into the SQL query string. There is no allow-list validation, no type casting to integer, and no prepared statement binding, which are the standard defenses against [CWE-89].

Attack Vector

An attacker sends a crafted HTTP request to the vulnerable endpoint with a malicious payload in the id parameter, for example a Boolean-based or UNION-based payload. Successful injection allows reading arbitrary tables, modifying records, or destroying data in the gate pass database. Because the endpoint performs a DELETE, attackers can also alter the WHERE clause to delete rows beyond the department originally targeted.

No verified proof-of-concept code has been published in a curated exploit database. Refer to the GitHub SQL Vulnerability Details writeup and VulDB entry #272351 for further technical context.

Detection Methods for CVE-2024-7069

Indicators of Compromise

HTTP requests to /employee_gatepass/classes/Master.php?f=delete_department containing SQL metacharacters such as ', --, UNION, SLEEP(, or OR 1=1 in the id parameter.
Web server or PHP error logs referencing SQL syntax errors originating from the delete_department handler.
Unexpected DELETE operations against the departments table or related tables in the gate pass database.

Detection Strategies

Deploy Web Application Firewall (WAF) rules that inspect requests to Master.php and block payloads matching common SQL injection signatures in the id parameter.
Enable database query logging and alert on DELETE statements with anomalous WHERE clauses affecting more than one row.
Use static analysis on the PHP source to flag any unsanitized concatenation of $_GET or $_POST input into SQL strings within classes/Master.php.

Monitoring Recommendations

Forward web server access logs and PHP error logs to a centralized analytics platform and build detections for SQL injection patterns against the employee_gatepass path.
Baseline normal request volumes to Master.php and alert on sudden spikes, which often indicate automated exploitation attempts.
Track authentication events preceding requests to delete_department to correlate low-privileged accounts with abusive behavior.

How to Mitigate CVE-2024-7069

Immediate Actions Required

Restrict network access to the Employee and Visitor Gate Pass Logging System so it is not reachable from the public internet.
Audit the departments table and related records for unauthorized modifications or deletions.
Rotate credentials for any application accounts that interact with the database if compromise is suspected.

Patch Information

No official vendor patch has been published for SourceCodester Employee and Visitor Gate Pass Logging System 1.0 as referenced in the NVD entry. Operators should treat the product as end-of-support for security purposes and consider migrating to an actively maintained alternative. For tracking updates, monitor the VulDB entry associated with this CVE.

Workarounds

Modify classes/Master.php to cast the id parameter to an integer with intval() before use, or refactor the query to use PDO prepared statements with bound parameters.
Place the application behind a WAF with SQL injection rulesets tuned for PHP applications, and enforce authentication in front of /employee_gatepass/.
Apply least-privilege permissions to the database account used by the application so it cannot perform operations beyond those required by the app.

bash

# Example hardening: block the vulnerable endpoint at the reverse proxy until patched
# nginx snippet
location ~* /employee_gatepass/classes/Master\.php {
    deny all;
    return 403;
