CVE-2025-63689 identifies multiple SQL injection vulnerabilities in the ycf1998 money-pos system, a point-of-sale software used for financial transactions. These vulnerabilities exist in versions prior to the commit 11f276bd20a41f089298d804e43cb1c39d041e59, dated September 14, 2025. The core issue lies in improper sanitization of the 'orderby' parameter, which is used in SQL queries to sort data. An attacker can inject malicious SQL code through this parameter, enabling them to manipulate the database queries executed by the system. This can lead to unauthorized data access, data modification, or even remote code execution if the database or application environment allows it. Since the vulnerability is exploitable remotely without authentication, attackers can target exposed POS systems over the network. The absence of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the potential for arbitrary code execution elevates its risk profile. No patches or exploit code are currently publicly available, but organizations should treat this as a critical threat due to the sensitive nature of POS systems and the financial data they handle.

For European organizations, the impact of CVE-2025-63689 could be severe. POS systems are integral to retail, hospitality, and financial sectors, and compromise could lead to theft of payment card data, financial fraud, and disruption of business operations. Exploitation could result in unauthorized access to sensitive customer and transaction data, damaging confidentiality and integrity. Additionally, arbitrary code execution could allow attackers to install malware, pivot within networks, or disrupt availability of payment services. Given the strict regulatory environment in Europe, including GDPR and PCI DSS compliance requirements, breaches stemming from this vulnerability could lead to significant legal penalties and reputational damage. The risk is heightened for organizations with internet-facing POS systems or those lacking network segmentation and robust input validation controls.

Organizations should immediately identify all instances of the ycf1998 money-pos system in their environment and verify the version against the vulnerable commit. Until a patch or update is released, implement strict input validation and sanitization on the 'orderby' parameter at the application or web server level. Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this parameter. Network segmentation should isolate POS systems from broader corporate networks and restrict access to trusted sources only. Monitor logs for unusual query patterns or failed SQL commands related to the orderby parameter. Conduct thorough security assessments and penetration testing focused on injection flaws. Prepare incident response plans specific to POS compromise scenarios. Once a vendor patch is available, prioritize immediate deployment and verify remediation through testing.
