CVE-2025-8274: Campcodes Recruitment System SQLi Flaw

CVE-2025-8274 Overview

A critical SQL injection vulnerability has been identified in Campcodes Online Recruitment Management System version 1.0. The vulnerability exists in the /admin/ajax.php?action=save_recruitment_status endpoint, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially enabling unauthorized access to sensitive database information, data manipulation, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive recruitment data, modify database records, or potentially escalate to full system compromise through database server exploitation.

Technical Details for CVE-2025-8274

Vulnerability Analysis

This SQL injection vulnerability stems from insufficient input validation in the recruitment status management functionality. The affected endpoint /admin/ajax.php?action=save_recruitment_status processes the ID parameter without proper sanitization, allowing attacker-controlled input to be directly incorporated into SQL queries executed against the backend database.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where untrusted data is sent to an interpreter as part of a command or query. The network-accessible nature of this vulnerability means attackers can exploit it remotely, and the low complexity of exploitation makes it particularly dangerous for exposed systems.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries (prepared statements) when handling the ID parameter in the AJAX endpoint. The application directly concatenates user-supplied input into SQL queries without sanitization, escaping, or the use of parameterized queries that would prevent SQL injection attacks.

Attack Vector

The attack can be launched remotely over the network against the vulnerable endpoint. An attacker sends a crafted HTTP request to /admin/ajax.php?action=save_recruitment_status with a malicious payload in the ID parameter. The payload contains SQL injection syntax designed to manipulate the database query structure, allowing the attacker to:

1. Extract sensitive data from the database using UNION-based or blind SQL injection techniques
2. Modify or delete recruitment records and other database content
3. Potentially escalate privileges if the database user has elevated permissions
4. Execute stored procedures or access underlying operating system functionality depending on database configuration

The exploit has been publicly disclosed, as documented in the GitHub CVE Issue #1, increasing the risk of active exploitation.

Detection Methods for CVE-2025-8274

Indicators of Compromise

• Unusual HTTP requests to /admin/ajax.php?action=save_recruitment_status containing SQL syntax characters such as single quotes, semicolons, UNION statements, or comment sequences (--, /*)
• Database error messages appearing in web server logs or application responses indicating malformed SQL queries
• Unexpected database queries in database audit logs, particularly those containing injection patterns
• Anomalous data modifications in recruitment-related database tables

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the /admin/ajax.php endpoint
• Monitor HTTP request logs for suspicious ID parameter values containing special characters or SQL keywords
• Enable database query logging and alert on queries with unusual patterns or syntax errors
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Configure real-time alerting for web server access logs filtering requests to the vulnerable endpoint with injection patterns
• Establish baseline monitoring of database query patterns and alert on deviations that may indicate exploitation
• Review authentication and authorization logs for unauthorized access attempts following potential SQL injection exploitation
• Implement application-level logging to capture all input to the vulnerable parameter for forensic analysis

How to Mitigate CVE-2025-8274

Immediate Actions Required

• Restrict network access to the Campcodes Online Recruitment Management System administration interface to trusted IP addresses only
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules in front of the application
• Disable or remove the vulnerable endpoint /admin/ajax.php?action=save_recruitment_status if the functionality is not critical
• Implement network segmentation to isolate the database server from direct internet access

Patch Information

At the time of publication, no vendor patch has been released for this vulnerability. Organizations using Campcodes Online Recruitment Management System 1.0 should contact the vendor for remediation guidance and monitor the VulDB entry for updates. In the absence of an official patch, implementing the recommended workarounds is critical to reducing exposure.

Workarounds

• Apply input validation at the application level by modifying the source code to use parameterized queries or prepared statements for all database interactions
• Implement strict input filtering to reject requests containing SQL injection characters in the ID parameter
• Configure the database user account used by the application with minimal privileges (principle of least privilege) to limit the impact of successful exploitation
• Place the application behind a reverse proxy with SQL injection detection and blocking capabilities
• Consider taking the application offline until a proper fix can be implemented if it handles sensitive recruitment data

# Example: Restrict access to admin directory using .htaccess
# Add to /admin/.htaccess
<Files "ajax.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Files>
