CVE-2025-7557 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Voting System, specifically within the /admin/voters_row.php file. The vulnerability arises due to improper sanitization or validation of the 'ID' parameter, which can be manipulated by an attacker to inject malicious SQL code. This injection flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits have been observed in the wild to date. The CVSS 4.0 base score is 5.3 (medium severity), reflecting that the attack vector is network-based with low attack complexity and no privileges or user interaction required. However, the impact on confidentiality, integrity, and availability is limited (low) because the vulnerability affects a specific administrative function and the scope is local to the vulnerable system. The Voting System is typically used to manage voting or polling data, so exploitation could lead to unauthorized data access, modification, or deletion of voter records, potentially undermining the integrity of voting results or administrative data. The lack of available patches or mitigations from the vendor increases the urgency for organizations to implement compensating controls.

For European organizations using the code-projects Voting System 1.0, this vulnerability poses a risk to the integrity and confidentiality of voting or polling data. Exploitation could allow attackers to manipulate voter records, potentially altering election outcomes or poll results, which is especially critical in contexts where voting systems influence decision-making or public opinion. The ability to remotely exploit the vulnerability without authentication increases the threat level, as attackers can operate from outside the network perimeter. While the vulnerability's impact on availability is limited, the reputational damage and loss of trust in affected organizations could be significant. Additionally, unauthorized data access may lead to violations of the EU's GDPR regulations, resulting in legal and financial penalties. Organizations involved in political processes, public administration, or any sector relying on voting systems should consider this vulnerability a serious concern.

Given the absence of official patches, European organizations should immediately implement the following mitigations: 1) Restrict access to the /admin/voters_row.php endpoint by IP whitelisting or VPN-only access to limit exposure to trusted administrators. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'ID' parameter. 3) Conduct thorough input validation and sanitization on all parameters, especially 'ID', using parameterized queries or prepared statements if possible within the application code. 4) Monitor logs for unusual database queries or repeated access attempts to the vulnerable endpoint. 5) If feasible, isolate the voting system in a segmented network zone with strict access controls. 6) Plan and prioritize upgrading to a newer, patched version of the Voting System once available or consider alternative secure voting platforms. 7) Educate administrative users about the risks and encourage strong authentication methods to reduce the risk of lateral movement if exploited.
