CVE-2025-8336 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Recruitment Management System. The vulnerability resides in the /admin/ajax.php endpoint, specifically when handling the 'action=save_user' request parameter. The issue arises from improper sanitization or validation of the 'ID' argument, which allows an attacker to inject malicious SQL code. This injection can be performed remotely without any authentication or user interaction, making exploitation straightforward. Successful exploitation could enable an attacker to manipulate the backend database, potentially leading to unauthorized data disclosure, data modification, or even complete compromise of the recruitment system's database. Given that the recruitment system likely stores sensitive personal data such as candidate resumes, contact details, and employment history, the confidentiality and integrity of this data are at significant risk. The CVSS 4.0 base score is 6.9, indicating a medium severity level, reflecting the ease of exploitation (network attack vector, no privileges or user interaction required) but limited scope and impact (low to limited confidentiality, integrity, and availability impacts). No known exploits are currently reported in the wild, but public disclosure of the exploit code increases the risk of imminent attacks. The lack of available patches or mitigation guidance from the vendor further exacerbates the threat landscape for users of this software version.

For European organizations using the Campcodes Online Recruitment Management System version 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive recruitment data. Exploitation could lead to unauthorized access to personal identifiable information (PII) of job applicants and employees, potentially violating GDPR requirements and resulting in legal and financial penalties. Additionally, attackers could alter recruitment data, disrupting hiring processes and damaging organizational reputation. The remote, unauthenticated nature of the attack vector increases the likelihood of exploitation, especially in organizations with internet-facing recruitment portals. The impact extends beyond data breaches to potential operational disruptions if the database integrity is compromised. Given the critical nature of recruitment data and the regulatory environment in Europe, organizations face both compliance risks and operational challenges if this vulnerability is exploited.

Organizations should immediately audit their deployment of the Campcodes Online Recruitment Management System to identify if version 1.0 is in use. Since no official patches are currently available, the following specific mitigations are recommended: 1) Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the /admin/ajax.php?action=save_user endpoint, focusing on the 'ID' parameter. 2) Restrict access to the administration interface by IP whitelisting or VPN-only access to reduce exposure to remote attackers. 3) Conduct thorough input validation and sanitization at the application layer if custom modifications are possible, ensuring all user-supplied inputs are properly escaped or parameterized in SQL queries. 4) Monitor logs for unusual database query patterns or repeated failed attempts targeting the vulnerable endpoint. 5) Prepare for rapid patch deployment once the vendor releases an official fix, and consider temporary migration to alternative recruitment management solutions if feasible. 6) Educate internal security teams and administrators about the vulnerability and signs of exploitation to enable prompt detection and response.
