CVE-2025-8950: Campcodes Recruitment System SQLi Flaw

CVE-2025-8950 Overview

A SQL injection vulnerability has been identified in Campcodes Online Recruitment Management System version 1.0. This vulnerability exists in the file /Recruitment/index.php?page=view_vacancy where improper handling of the ID argument allows attackers to inject malicious SQL queries. The attack can be initiated remotely without authentication, and proof-of-concept exploit information has been publicly disclosed.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data from the database, potentially compromising candidate personal information, recruitment records, and administrative credentials stored in the system.

Technical Details for CVE-2025-8950

Vulnerability Analysis

This vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly known as Injection. The affected component processes user-supplied input through the ID parameter without adequate sanitization or parameterized query implementation. When a user accesses the vacancy viewing functionality, the application directly incorporates the ID parameter value into SQL queries, creating an injection point that attackers can exploit.

The network-accessible nature of this vulnerability means that any remote attacker with access to the application can attempt exploitation without requiring prior authentication or user interaction. The vulnerability affects data confidentiality, integrity, and availability of the underlying database system.

Root Cause

The root cause of this vulnerability stems from inadequate input validation and the use of dynamic SQL query construction. The application fails to properly sanitize or escape user-supplied data in the ID parameter before incorporating it into database queries. Instead of using prepared statements or parameterized queries, the application appears to concatenate user input directly into SQL statements, enabling attackers to manipulate query logic.

Attack Vector

An attacker can exploit this vulnerability by crafting malicious HTTP requests to the vulnerable endpoint /Recruitment/index.php?page=view_vacancy with a specially crafted ID parameter containing SQL injection payloads. The attack is network-based and requires no authentication or privileges, making it accessible to any remote attacker who can reach the application.

Typical exploitation scenarios include:

• Union-based SQL injection to extract data from other database tables
• Boolean-based blind SQL injection to enumerate database contents
• Time-based blind SQL injection when direct output is not visible
• Potential for database manipulation or privilege escalation depending on database permissions

The vulnerability affects the vacancy viewing functionality, suggesting that attackers could potentially access sensitive recruitment data, candidate information, and administrative records stored in the database.

Detection Methods for CVE-2025-8950

Indicators of Compromise

• Unusual database query patterns originating from web application logs targeting /Recruitment/index.php?page=view_vacancy
• HTTP requests containing SQL injection payloads (e.g., UNION SELECT, ' OR 1=1, time-based functions) in the ID parameter
• Unexpected database errors or application crashes when accessing vacancy viewing functionality
• Evidence of data exfiltration or unauthorized database access in database audit logs

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the ID parameter
• Monitor web server access logs for requests to /Recruitment/index.php?page=view_vacancy with suspicious parameter values
• Enable database query logging and alert on anomalous query patterns or syntax errors
• Deploy intrusion detection systems (IDS) with SQL injection detection signatures

Monitoring Recommendations

• Configure real-time alerting for SQL injection patterns in application firewall logs
• Establish baseline normal traffic patterns to the recruitment application and alert on deviations
• Monitor database user activity for unexpected queries or data access patterns
• Review application error logs regularly for SQL syntax errors that may indicate exploitation attempts

How to Mitigate CVE-2025-8950

Immediate Actions Required

• Restrict access to the Campcodes Online Recruitment Management System to trusted networks only using firewall rules
• Implement a Web Application Firewall (WAF) to filter SQL injection attempts targeting the vulnerable endpoint
• Disable or remove the affected view_vacancy functionality if not critical to operations
• Audit database access logs for any evidence of prior exploitation

Patch Information

At the time of publication, no official patch has been released by Campcodes for this vulnerability. Organizations using this software should monitor the Campcodes website for security updates and consider implementing compensating controls until a patch becomes available. Additional vulnerability details can be found in the VulDB CTI entry.

Workarounds

• Deploy a Web Application Firewall configured to block SQL injection attacks on the affected endpoint
• Implement network-level access controls to limit who can reach the recruitment management system
• If source code access is available, modify the affected file to use parameterized queries or prepared statements for the ID parameter
• Consider temporarily disabling the vulnerable functionality until a proper fix is implemented
• Implement input validation at the application layer to allow only numeric values for the ID parameter

# Example WAF rule for ModSecurity to block SQL injection on the affected endpoint
SecRule REQUEST_URI "@contains /Recruitment/index.php" \
  "id:100001,\
  phase:2,\
