CVE-2025-7436 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Recruitment Management System. The vulnerability exists in the /admin/ajax.php endpoint, specifically when handling the 'delete_vacancy' action. The flaw arises from improper sanitization or validation of the 'ID' parameter, which an attacker can manipulate to inject arbitrary SQL commands. This injection can be exploited remotely without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the underlying database, potentially allowing attackers to extract sensitive recruitment data, modify or delete records, or disrupt service operations. Although the CVSS score is 6.9 (medium severity), the exploitability is high due to the lack of required privileges and user interaction. No official patches or fixes have been published yet, and while no known exploits are currently in the wild, public disclosure increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is an online recruitment management system likely used by HR departments and recruitment agencies to manage job vacancies and candidate information.

For European organizations using Campcodes Online Recruitment Management System version 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive candidate and recruitment data, including personal identifiable information (PII), which is protected under GDPR. Data breaches could result in regulatory penalties, reputational damage, and loss of trust. Additionally, attackers could manipulate or delete vacancy postings, disrupting recruitment operations and causing business continuity issues. The ability to execute arbitrary SQL commands remotely without authentication increases the likelihood of widespread exploitation, especially if organizations have not implemented compensating controls. Given the critical nature of recruitment data and its role in organizational HR functions, the impact extends beyond data loss to operational disruption and compliance violations.

Organizations should immediately assess their use of Campcodes Online Recruitment Management System version 1.0 and plan for an upgrade or patch deployment once available. In the absence of official patches, implement the following mitigations: 1) Apply Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the /admin/ajax.php?action=delete_vacancy endpoint, focusing on the 'ID' parameter. 2) Restrict access to the administration interface by IP whitelisting or VPN-only access to reduce exposure. 3) Conduct input validation and sanitization on all parameters, especially 'ID', to reject unexpected or malicious input. 4) Monitor logs for suspicious activity related to the vulnerable endpoint. 5) Isolate the recruitment management system network segment to limit lateral movement in case of compromise. 6) Prepare incident response plans to quickly address potential exploitation. 7) Engage with the vendor for timely patch releases and updates.
