CVE-2025-47599 is a critical SQL Injection vulnerability (CWE-89) affecting the Facturante product, versions up to 1.11. SQL Injection occurs when an application improperly neutralizes special elements in SQL commands, allowing an attacker to inject malicious SQL code. This vulnerability enables remote attackers to execute arbitrary SQL queries on the backend database without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The vulnerability has a CVSS score of 9.3, reflecting its critical severity. The scope is marked as changed (S:C), meaning exploitation can affect resources beyond the vulnerable component, potentially impacting the entire database or connected systems. The impact on confidentiality is high (C:H), allowing attackers to read sensitive data, but integrity impact is none (I:N), and availability impact is low (A:L), indicating limited disruption to service. No known exploits are currently reported in the wild, and no patches have been linked yet. Given the nature of SQL Injection, attackers could extract sensitive financial or personal data, manipulate queries to bypass authentication or authorization, or perform other malicious database operations. Facturante is a billing/invoicing software, so the data at risk likely includes financial records, client information, and transactional data, which are highly sensitive.

For European organizations using Facturante, this vulnerability poses a significant risk to the confidentiality of sensitive financial and client data. Exploitation could lead to unauthorized data disclosure, potentially violating GDPR and other data protection regulations, resulting in legal and financial penalties. The ability to execute arbitrary SQL commands without authentication increases the risk of large-scale data breaches. Even though integrity and availability impacts are low or none, the exposure of confidential data alone can damage organizational reputation and trust. Given the critical nature of the vulnerability and the lack of patches, organizations may face increased risk of targeted attacks, especially from financially motivated threat actors. The vulnerability could also be leveraged in supply chain attacks if Facturante is integrated with other financial or ERP systems common in European enterprises.

1. Immediate mitigation should include restricting external access to the Facturante application, ideally isolating it within internal networks or VPNs to reduce exposure. 2. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection patterns targeting Facturante endpoints. 3. Monitor database query logs for unusual or suspicious activity indicative of injection attempts. 4. Conduct a thorough code review and input validation audit of Facturante, focusing on all SQL query construction points, to identify and remediate unsafe dynamic SQL usage. 5. Engage with the vendor or community to obtain patches or updates as soon as they become available. 6. As a longer-term measure, consider migrating to alternative invoicing solutions with proven secure coding practices if patching is delayed. 7. Educate internal security teams on this vulnerability to increase vigilance and incident response readiness. 8. Ensure regular backups of databases are maintained and tested to enable recovery in case of compromise.
