CVE-2025-11288 is a SQL injection vulnerability affecting CRMEB, a customer relationship management and e-commerce platform, in all versions up to 5.6. The vulnerability arises from improper sanitization or validation of the GET parameter cate_id in the /adminapi/product/product endpoint. By manipulating this parameter, an attacker can inject malicious SQL queries, potentially allowing unauthorized access to the backend database, data exfiltration, or modification of sensitive information. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing its risk profile. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L - low privileges), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Despite early notification, the vendor has not issued patches or advisories, and public exploit code is available, which could facilitate widespread exploitation. This vulnerability primarily affects organizations using CRMEB versions 5.0 through 5.6, especially those exposing the vulnerable endpoint to untrusted networks.

The SQL injection vulnerability can lead to unauthorized access to sensitive customer and product data stored in the CRMEB backend database. Attackers could extract confidential information, modify or delete records, or escalate privileges within the application. This can result in data breaches, loss of customer trust, regulatory penalties, and operational disruption. Since the flaw is remotely exploitable without authentication, attackers can automate attacks at scale, increasing the likelihood of compromise. Organizations relying on CRMEB for critical business functions such as customer management, sales, and inventory control face risks of data integrity loss and service disruption. The absence of vendor patches and public exploit availability further elevates the threat level, potentially impacting a wide range of businesses globally.

Given the lack of official patches, organizations should immediately implement compensating controls. These include deploying web application firewalls (WAFs) with custom rules to detect and block malicious SQL injection payloads targeting the cate_id parameter on the /adminapi/product/product endpoint. Restrict network access to the vulnerable API endpoint to trusted internal IPs only, avoiding exposure to the public internet. Conduct thorough input validation and sanitization on all GET parameters, especially cate_id, to prevent injection attacks. Monitor application logs and network traffic for suspicious activity indicative of SQL injection attempts. Consider temporarily disabling or restricting access to the vulnerable endpoint until a vendor patch is available. Organizations should also plan for timely updates once official fixes are released and perform security assessments to identify any exploitation attempts.
