CVE-2025-7136 Overview
A critical SQL Injection vulnerability has been identified in Campcodes Online Recruitment Management System version 1.0. The vulnerability exists in the /admin/view_vacancy.php file where the ID parameter is not properly sanitized before being used in SQL queries. This flaw allows remote attackers to inject malicious SQL commands, potentially leading to unauthorized data access, data modification, or complete database compromise.
Critical Impact
Remote attackers can exploit this SQL Injection vulnerability to extract sensitive recruitment data, modify database contents, or potentially gain unauthorized access to the underlying system without authentication.

Technical Details for CVE-2025-7136
Vulnerability Analysis
This SQL Injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) occurs due to insufficient input validation in the administrative vacancy viewing functionality. The ID parameter in /admin/view_vacancy.php is directly incorporated into SQL queries without proper sanitization or parameterization.
When an attacker supplies a crafted ID value containing SQL metacharacters, the application fails to treat this input as data and instead interprets portions of it as executable SQL commands. This allows attackers to manipulate the query logic, extract data from other tables, or perform administrative operations on the database.
The attack surface is particularly concerning as the vulnerability exists in an administrative endpoint, which may contain sensitive recruitment data including applicant personal information, employment history, and internal HR communications.
Root Cause
The root cause of this vulnerability is the lack of proper input sanitization and the absence of parameterized queries (prepared statements) in the application's database interaction layer. The ID parameter is concatenated directly into SQL query strings, creating a classic SQL Injection attack surface. This represents a fundamental secure coding violation where user-controlled input is trusted without validation.
Attack Vector
The vulnerability is exploitable remotely via the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests to the /admin/view_vacancy.php endpoint with a manipulated ID parameter containing SQL injection payloads.
Exploitation typically involves sending requests with payloads designed to:
- Extract data using UNION-based injection techniques
- Enumerate database structure through error-based injection
- Perform blind SQL injection using time-based or boolean-based techniques
- Potentially execute stored procedures or administrative commands
The exploit has been publicly disclosed, as documented in the GitHub CVE Issue Discussion, increasing the risk of active exploitation.
Detection Methods for CVE-2025-7136
Indicators of Compromise
- Unusual SQL error messages in web server logs from /admin/view_vacancy.php
- HTTP requests to /admin/view_vacancy.php containing SQL metacharacters such as single quotes, double dashes, or UNION SELECT statements in the ID parameter
- Unexpected database query patterns including time delays or large data extractions
- Access logs showing repeated requests to the vulnerable endpoint with varying ID values
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the ID parameter
- Monitor database query logs for anomalous queries originating from the recruitment management application
- Deploy application-layer intrusion detection to identify SQL injection attack signatures
- Review access logs for suspicious patterns targeting /admin/view_vacancy.php
Monitoring Recommendations
- Enable verbose logging on the web server and database to capture all queries and request parameters
- Set up alerting for SQL error messages that may indicate injection attempts
- Monitor for unusual data exfiltration patterns from the recruitment database
- Implement real-time log analysis to detect attack patterns against the vulnerable endpoint
How to Mitigate CVE-2025-7136
Immediate Actions Required
- Restrict access to /admin/view_vacancy.php using IP whitelisting or additional authentication controls
- Implement input validation on the ID parameter to accept only numeric values
- Deploy a Web Application Firewall with SQL injection protection rules
- Consider taking the affected functionality offline until a proper fix is applied
- Audit database access logs for signs of prior exploitation
Patch Information
No official vendor patch information is currently available for CVE-2025-7136. Organizations using Campcodes Online Recruitment Management System 1.0 should contact the vendor directly for remediation guidance or apply the recommended workarounds immediately.
For additional technical details, refer to the VulDB entry #315048 or the GitHub CVE Issue Discussion.
Workarounds
- Implement server-side input validation to ensure the ID parameter contains only numeric characters
- Use parameterized queries or prepared statements in the application code to prevent SQL injection
- Deploy a WAF with rules specifically targeting SQL injection in the ID parameter
- Restrict network access to administrative endpoints using firewall rules or VPN requirements
- Apply the principle of least privilege to the database user account used by the application
# Example: Apache mod_rewrite rule to block non-numeric ID values
# Add to .htaccess or Apache configuration
RewriteEngine On
RewriteCond %{QUERY_STRING} ID=[^0-9] [NC]
RewriteRule ^admin/view_vacancy\.php$ - [F,L]
