CVE-2025-7556 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Voting System, specifically within an unspecified function in the /admin/voters_edit.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is susceptible to malicious input manipulation. An attacker can exploit this flaw remotely without requiring user interaction or authentication, allowing them to inject crafted SQL commands into the backend database queries. This can lead to unauthorized data access, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the voting system's data. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits are currently reported in the wild. The CVSS 4.0 base score is 5.3, indicating a medium severity level, reflecting the ease of remote exploitation but limited impact scope due to partial confidentiality, integrity, and availability impacts and the requirement of low privileges.

For European organizations using the code-projects Voting System 1.0, this vulnerability poses significant risks. Voting systems often handle sensitive personal data and critical electoral information, so exploitation could lead to unauthorized disclosure of voter information, manipulation of voting records, or disruption of election processes. Such impacts could undermine public trust, violate data protection regulations like GDPR, and cause reputational damage. Even if the affected product is not widely deployed, organizations relying on this system for internal or local elections could face operational disruptions. The medium severity score suggests that while the vulnerability is exploitable remotely without user interaction, the requirement for low privileges may limit the attacker's initial access, somewhat mitigating the risk. However, the public disclosure increases the urgency for mitigation to prevent potential exploitation.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include: 1) Restricting access to the /admin/voters_edit.php endpoint through network segmentation and firewall rules to trusted IP addresses only. 2) Employing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'ID' parameter. 3) Conducting thorough input validation and sanitization on all user-supplied data, especially parameters used in SQL queries, ideally using parameterized queries or prepared statements if source code modification is possible. 4) Monitoring logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 5) Planning for an upgrade or replacement of the vulnerable Voting System version once a vendor patch or secure alternative is available. 6) Educating administrators about the vulnerability and ensuring strict credential management to prevent privilege escalation.
