CVE-2025-15443 is a SQL injection vulnerability identified in CRMEB, a customer relationship management and e-commerce platform, affecting versions 5.6.0 and 5.6.1. The vulnerability resides in the processing of the cate_id parameter within the /adminapi/product/product_export API endpoint. Improper input validation or sanitization allows an attacker with high privileges to inject malicious SQL queries remotely, potentially leading to unauthorized data access, modification, or deletion. The vulnerability does not require user interaction but does require authentication with elevated privileges, limiting the attack surface to authenticated users with admin or similar rights. The CVSS 4.0 score of 5.1 reflects a medium severity, considering the network attack vector, low complexity, no user interaction, but requiring privileges. The impact on confidentiality, integrity, and availability is low to moderate, as the vulnerability could allow data leakage or manipulation but is constrained by the privilege requirement. No patches or vendor responses have been issued, and while no active exploitation in the wild is confirmed, publicly available exploit code increases the risk of future attacks. Organizations relying on CRMEB should assess their exposure, especially if they use the affected versions and expose the vulnerable API endpoint.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive customer and product data managed within CRMEB, potentially resulting in data breaches, regulatory non-compliance (e.g., GDPR violations), and reputational damage. The integrity of product export data could be compromised, affecting business operations and decision-making. Although exploitation requires high privileges, insider threats or compromised admin accounts could leverage this flaw to escalate damage. Availability impact is limited but possible if attackers manipulate database queries to cause service disruptions. Industries with high CRMEB adoption, such as retail, e-commerce, and customer service sectors, are at greater risk. The lack of vendor response and patches increases the window of exposure, necessitating proactive defensive measures. European organizations must consider the legal and financial consequences of data breaches under strict data protection laws.

Immediate mitigation steps include restricting access to the /adminapi/product/product_export endpoint to trusted administrators only and implementing strict network segmentation and access controls around CRMEB administrative interfaces. Organizations should audit and monitor logs for suspicious activity related to cate_id parameter usage. Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this endpoint. Since no official patch is available, consider applying virtual patching or input validation proxies to sanitize cate_id inputs. Review and enforce the principle of least privilege for CRMEB users, ensuring only necessary accounts have high-level access. Regularly back up CRMEB databases to enable recovery in case of data manipulation. Engage with CRMEB vendors or community forums for updates or unofficial patches. Finally, conduct penetration testing focused on this vulnerability to validate defenses.
