CVE-2025-11288 is a medium-severity SQL Injection vulnerability affecting CRMEB versions 5.0 through 5.6. The flaw exists in the GET parameter handler of the /adminapi/product/product endpoint, specifically involving the cate_id parameter. An attacker can manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access or modification of the backend database. The vulnerability is remotely exploitable without user interaction or authentication, increasing its risk profile. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no user interaction, and partial impacts on confidentiality, integrity, and availability. Although the vendor was notified, no patch or response has been issued, and no known exploits are currently observed in the wild. The public release of the exploit code raises the likelihood of future exploitation. This vulnerability could allow attackers to extract sensitive data, modify or delete records, or disrupt service availability within CRMEB deployments, which are commonly used for e-commerce and customer relationship management.

For European organizations using CRMEB versions up to 5.6, this vulnerability poses a significant risk to data confidentiality, integrity, and availability. Exploitation could lead to unauthorized data disclosure, including customer and transactional information, potentially violating GDPR and other data protection regulations. Integrity compromises could result in fraudulent transactions or corrupted business data, undermining trust and operational reliability. Availability impacts could disrupt e-commerce operations, causing financial losses and reputational damage. Given CRMEB's role in managing product and customer data, attacks could also facilitate further lateral movement or privilege escalation within affected networks. The lack of vendor response and patches increases exposure time, making European organizations more vulnerable, especially those with public-facing CRMEB installations.

European organizations should immediately audit their CRMEB installations to identify affected versions (5.0 to 5.6). Until a vendor patch is available, implement strict input validation and sanitization on the cate_id parameter at the web application firewall (WAF) or reverse proxy level to block malicious SQL payloads. Employ runtime application self-protection (RASP) tools to detect and prevent SQL injection attempts dynamically. Restrict access to the /adminapi/product/product endpoint by IP whitelisting or VPN-only access to reduce exposure. Monitor logs for unusual query patterns or errors indicative of injection attempts. Consider deploying database activity monitoring to detect anomalous queries. Plan for rapid patching once an official fix is released, and conduct penetration testing to verify the effectiveness of mitigations. Additionally, ensure regular backups and incident response plans are in place to recover from potential data integrity or availability incidents.
