CVE-2025-11288 is a SQL injection vulnerability identified in CRMEB, a customer relationship management and e-commerce platform, affecting versions 5.0 through 5.6. The flaw resides in the GET parameter handler of the /adminapi/product/product endpoint, specifically in the processing of the cate_id parameter. An attacker can manipulate this parameter to inject malicious SQL code, enabling unauthorized access to the underlying database. The vulnerability is remotely exploitable without requiring authentication or user interaction, which significantly lowers the barrier for attackers. The vendor was notified but has not issued any patches or advisories, and public exploit code has been released, increasing the likelihood of exploitation. The CVSS 4.0 base score is 5.3, indicating a medium severity level. The attack vector is network-based with low attack complexity and no privileges required. The vulnerability impacts confidentiality by potentially exposing sensitive data, integrity by allowing unauthorized data modification, and availability by possibly enabling denial-of-service conditions through crafted queries. The scope is limited to the CRMEB installations running vulnerable versions, but given the public exploit availability, the risk is non-negligible. No official patches or mitigations have been published, leaving organizations reliant on defensive measures such as input validation and network controls.

For European organizations using CRMEB, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their customer and product data. Exploitation could lead to unauthorized data disclosure, data tampering, or disruption of e-commerce services, damaging business operations and customer trust. Given the remote and unauthenticated nature of the exploit, attackers can target internet-facing admin APIs directly, increasing exposure. This is particularly critical for organizations handling sensitive personal data under GDPR, as breaches could result in regulatory penalties and reputational harm. The lack of vendor response and absence of patches exacerbate the threat, forcing organizations to rely on compensating controls. The medium severity score suggests that while the vulnerability is serious, it may require some technical skill to exploit effectively. However, the public availability of exploit code lowers this barrier. Overall, the threat could disrupt business continuity and lead to financial losses and compliance issues for European entities relying on CRMEB.

1. Immediately implement strict input validation and sanitization on the cate_id parameter to prevent SQL injection attempts. 2. Employ parameterized queries or prepared statements in the backend code handling the /adminapi/product/product endpoint to eliminate direct SQL concatenation. 3. Restrict access to the /adminapi/product/product API endpoint using network-level controls such as IP whitelisting, VPNs, or web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns. 4. Monitor logs for unusual or suspicious activity targeting the cate_id parameter or the admin API endpoint. 5. If possible, isolate the CRMEB admin API behind an internal network segment inaccessible from the public internet. 6. Regularly back up databases and verify backup integrity to enable recovery in case of data corruption or deletion. 7. Engage with the CRMEB vendor or community to track any forthcoming patches or official advisories. 8. Consider deploying runtime application self-protection (RASP) tools to detect and block injection attacks dynamically. 9. Conduct security code reviews and penetration testing focused on injection vulnerabilities in CRMEB deployments. 10. Educate development and operations teams about the risks of SQL injection and secure coding practices.
