CVE-2025-6520 is a critical SQL Injection vulnerability identified in Abis Technology's BAPSIS software, a product used in various sectors potentially including critical infrastructure. The vulnerability arises from improper neutralization of special elements in SQL commands, classified under CWE-89. Specifically, the flaw allows attackers to perform Blind SQL Injection attacks remotely without requiring authentication or user interaction. Blind SQL Injection enables attackers to infer database information by sending crafted queries and analyzing responses, potentially leading to data exfiltration, unauthorized data modification, or complete system compromise. The vulnerability affects all versions of BAPSIS prior to the build dated 202510271606. The CVSS v3.1 base score is 9.8, reflecting a network attack vector with low complexity, no privileges or user interaction required, and impacts on confidentiality, integrity, and availability. Although no public exploits have been reported yet, the vulnerability's characteristics make it highly exploitable. The lack of available patches at the time of publication necessitates immediate defensive measures. The vulnerability's presence in a product like BAPSIS, which may be used in sensitive environments, increases the potential impact. Attackers exploiting this flaw could gain unauthorized access to backend databases, manipulate or destroy data, and disrupt services, posing significant risks to organizational operations and data security.

For European organizations, exploitation of CVE-2025-6520 could result in severe data breaches, loss of sensitive information, and operational disruptions. Organizations relying on BAPSIS for critical functions may face unauthorized data disclosure, data tampering, or denial of service conditions. This could affect sectors such as government, energy, transportation, or healthcare if BAPSIS is deployed there. The breach of confidentiality could expose personal data protected under GDPR, leading to regulatory penalties and reputational damage. Integrity violations could undermine trust in operational data, while availability impacts might disrupt essential services. The remote, unauthenticated nature of the attack increases the risk of widespread exploitation, especially if attackers automate the attack. The absence of known exploits currently provides a window for mitigation, but the critical severity demands rapid response to prevent potential attacks targeting European infrastructure or enterprises.

1. Immediate deployment of web application firewalls (WAFs) with rules to detect and block SQL Injection patterns targeting BAPSIS interfaces. 2. Implement strict input validation and sanitization on all user-supplied data, employing allowlists where possible. 3. Use parameterized queries or prepared statements in the application code to prevent injection of malicious SQL commands. 4. Restrict network access to BAPSIS management interfaces to trusted IP addresses and internal networks only. 5. Monitor logs for unusual database query patterns or repeated failed attempts indicative of SQL Injection probing. 6. Segment the network to isolate BAPSIS servers from critical backend systems and sensitive data repositories. 7. Prepare for rapid patch deployment once Abis Technology releases an official fix; establish communication channels with the vendor. 8. Conduct security awareness training for administrators on recognizing and responding to exploitation attempts. 9. Perform regular security assessments and penetration testing focused on injection vulnerabilities. 10. Maintain up-to-date backups and incident response plans to minimize impact if exploitation occurs.
