CVE-2025-7919 is a high-severity SQL Injection vulnerability found in the WinMatrix3 Web package developed by Simopro Technology. This vulnerability allows unauthenticated remote attackers to inject arbitrary SQL commands into the backend database. Exploitation of this flaw can lead to unauthorized reading, modification, and deletion of database contents. The vulnerability is categorized under CWE-200, indicating exposure of sensitive information to unauthorized actors. The CVSS 4.0 base score is 7.1, reflecting high severity with an attack vector of network (AV:N), low attack complexity (AC:L), no authentication required (AT:N), no privileges required (PR:L), and no user interaction (UI:N). The vulnerability impacts confidentiality significantly (VC:H), but has no impact on integrity (VI:N) or availability (VA:N). The scope is unchanged (SC:N), and there is no requirement for user interaction or privileges beyond low-level access. The affected version is listed as "0", which likely indicates initial or all versions prior to patching, though no patch links are currently available. No known exploits are reported in the wild yet. The vulnerability allows attackers to remotely and anonymously access the database through crafted SQL queries, potentially exposing sensitive data, corrupting records, or deleting critical information. This poses a serious risk to organizations using the WinMatrix3 Web package, especially if the database contains personal, financial, or operational data. The lack of authentication requirement and network accessibility make this vulnerability particularly dangerous, as attackers can exploit it without prior access or interaction with legitimate users.

For European organizations using the WinMatrix3 Web package, this vulnerability could lead to significant data breaches involving sensitive customer, employee, or operational data. Unauthorized data disclosure could violate GDPR and other data protection regulations, resulting in legal penalties and reputational damage. Data modification or deletion could disrupt business operations, cause financial losses, and impair service availability. Given the high confidentiality impact and ease of exploitation, attackers could leverage this vulnerability to conduct espionage, sabotage, or ransomware attacks. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly at risk due to the sensitivity of their data and the potential cascading effects of data corruption or loss. The absence of known exploits currently provides a window for proactive mitigation, but the vulnerability’s characteristics suggest it could be rapidly weaponized once publicly known. The exposure of sensitive information also increases the risk of follow-on attacks, including identity theft, fraud, and targeted phishing campaigns.

1. Immediate risk reduction should focus on isolating the affected WinMatrix3 Web package instances from external networks or restricting access via network segmentation and firewall rules to trusted IP ranges only. 2. Conduct a thorough code review and implement parameterized queries or prepared statements to eliminate SQL injection vectors in the application code. 3. Apply input validation and sanitization on all user-supplied data before processing SQL commands. 4. Monitor database logs for unusual or suspicious query patterns indicative of injection attempts. 5. Implement Web Application Firewalls (WAFs) with specific rules to detect and block SQL injection payloads targeting the WinMatrix3 Web package. 6. Since no official patches are currently available, maintain close communication with Simopro Technology for updates and apply patches promptly once released. 7. Perform regular backups of databases and verify their integrity to enable recovery in case of data tampering or deletion. 8. Conduct penetration testing and vulnerability scanning focused on SQL injection to identify and remediate any residual weaknesses. 9. Educate IT and security teams about this vulnerability to ensure rapid detection and response to potential exploitation attempts.
