CVE-2025-7217 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Payroll Management System. The vulnerability exists in the /ajax.php endpoint, specifically when handling the 'action=save_position' request parameter. The issue arises due to improper sanitization or validation of the 'ID' argument, which allows an attacker to inject malicious SQL code remotely without requiring any authentication or user interaction. This flaw can be exploited over the network (AV:N) with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the underlying database, as attackers can manipulate SQL queries to extract sensitive payroll data, modify records, or disrupt database operations. Although the CVSS 4.0 score is 6.9 (medium severity), the potential for data leakage or unauthorized modification in a payroll system elevates the risk profile. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability disclosure date is July 9, 2025. Given the critical nature of payroll data and the direct remote exploitation vector, this vulnerability demands urgent attention from organizations using this software version.

For European organizations, the exploitation of this SQL Injection vulnerability could lead to significant data breaches involving employee payroll information, including salaries, personal identification data, and banking details. Such breaches can result in financial fraud, identity theft, and regulatory non-compliance with GDPR and other data protection laws, potentially leading to heavy fines and reputational damage. Additionally, attackers could alter payroll data, causing payroll disruption and operational challenges. The integrity and availability of payroll systems are critical for business continuity; thus, exploitation could disrupt payroll processing cycles, affecting employee trust and organizational stability. Given the remote and unauthenticated nature of the exploit, attackers could target multiple organizations simultaneously, increasing the threat landscape across Europe. The lack of patches and public exploit code increases the urgency for proactive mitigation.

European organizations using Campcodes Payroll Management System 1.0 should immediately conduct a risk assessment to identify affected instances. Until an official patch is released, implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the /ajax.php?action=save_position endpoint, especially focusing on the 'ID' parameter. 2) Restrict network access to the payroll management system to trusted internal IP ranges or VPN-only access to reduce exposure. 3) Conduct thorough input validation and sanitization on all user-supplied parameters, particularly 'ID', if custom development or overrides are possible. 4) Monitor logs for unusual or repeated requests to the vulnerable endpoint indicative of exploitation attempts. 5) Prepare for rapid patch deployment by coordinating with Campcodes for updates or security advisories. 6) Consider isolating the payroll system in a segmented network zone to limit lateral movement if compromised. 7) Educate IT and security teams about this vulnerability to enhance detection and response capabilities.
