CVE-2025-7134: Campcodes Recruitment System SQLi Flaw

CVE-2025-7134 Overview

A critical SQL injection vulnerability has been discovered in Campcodes Online Recruitment Management System version 1.0. This vulnerability affects the /admin/ajax.php?action=delete_application endpoint, where improper handling of the ID argument allows attackers to inject malicious SQL statements. The vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to sensitive recruitment data, modification of database records, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive applicant data, modify recruitment records, or potentially gain unauthorized access to the underlying database system. The exploit has been publicly disclosed, increasing the risk of active exploitation.

Technical Details for CVE-2025-7134

Vulnerability Analysis

This SQL injection vulnerability exists in the administrative AJAX handler responsible for deleting job applications. The affected endpoint /admin/ajax.php?action=delete_application accepts an ID parameter that is directly incorporated into SQL queries without proper sanitization or parameterization. This classic injection pattern allows attackers to manipulate the query structure by injecting malicious SQL code through the ID parameter.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly referred to as injection vulnerabilities. The network-accessible nature of this endpoint means attackers can exploit this vulnerability remotely, without requiring any special privileges or user interaction.

Root Cause

The root cause of CVE-2025-7134 is the failure to implement proper input validation and parameterized queries in the application's database layer. The ID argument passed to the delete_application action is concatenated directly into SQL statements rather than being treated as a bound parameter. This allows special SQL characters and keywords in user input to break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack can be initiated remotely over the network against the administrative interface. An attacker crafts a malicious HTTP request to /admin/ajax.php?action=delete_application with a specially crafted ID parameter containing SQL injection payloads. Depending on the database configuration and application privileges, successful exploitation could enable:

• Extraction of sensitive recruitment data including applicant personal information
• Modification or deletion of database records
• Authentication bypass to access administrative functions
• Potential command execution if database features like xp_cmdshell or INTO OUTFILE are available

The exploit has been publicly disclosed, as documented in the GitHub Issue Discussion, increasing the likelihood of exploitation attempts in the wild.

Detection Methods for CVE-2025-7134

Indicators of Compromise

• HTTP requests to /admin/ajax.php?action=delete_application containing SQL syntax characters such as single quotes, semicolons, or SQL keywords like UNION, SELECT, DROP
• Unusual database errors or exceptions in application logs related to malformed SQL queries
• Unexpected changes to application or recruitment data in the database
• Evidence of data exfiltration attempts through time-based or error-based SQL injection techniques

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 suspicious requests targeting /admin/ajax.php with abnormal parameter values
• Configure database auditing to alert on unusual query patterns, failed queries, or mass data access operations
• Deploy application-level logging to capture and alert on injection attempt signatures

Monitoring Recommendations

• Enable detailed logging for all requests to administrative endpoints including /admin/ajax.php
• Set up real-time alerting for SQL syntax errors or database exceptions originating from the recruitment application
• Monitor for unusual database activity such as bulk data reads, schema queries, or privilege escalation attempts
• Regularly review access logs for scanning activity targeting known vulnerable endpoints

How to Mitigate CVE-2025-7134

Immediate Actions Required

• Restrict access to the administrative interface (/admin/) to trusted IP addresses or VPN connections only
• Implement a Web Application Firewall with SQL injection protection rules
• Consider temporarily disabling the delete_application functionality until a patch is available
• Review database access logs for evidence of prior exploitation

Patch Information

At the time of publication, no official vendor patch has been released for CVE-2025-7134. Organizations using Campcodes Online Recruitment Management System 1.0 should monitor the CampCodes Resource Page for security updates. Additional technical details and vulnerability tracking information can be found at VulDB #315046.

Workarounds

• Implement input validation at the application level to ensure the ID parameter contains only numeric values
• Deploy a reverse proxy or WAF to filter malicious SQL injection payloads before they reach the application
• Modify the vulnerable code to use parameterized queries or prepared statements for all database operations
• Apply principle of least privilege to the database user account used by the application to limit potential damage from successful exploitation

# Example: Apache mod_rewrite rule to block SQL injection attempts
# Add to .htaccess or Apache configuration
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|delete|drop|update|exec|script) [NC]
RewriteRule ^admin/ajax\.php$ - [F,L]
