CVE-2021-38736 is a critical SQL Injection vulnerability identified in SEMCMS Shop version 1.1, specifically exploitable via the Ant_Global.php script. SQL Injection (CWE-89) vulnerabilities occur when untrusted input is improperly sanitized and directly included in SQL queries, allowing attackers to manipulate backend databases. This vulnerability has a CVSS v3.1 base score of 9.8, indicating a critical severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) reveals that the attack can be performed remotely over the network without any authentication or user interaction, with low attack complexity. Successful exploitation can lead to full compromise of the confidentiality, integrity, and availability of the affected system's data. Attackers could extract sensitive information, modify or delete data, or even execute administrative commands on the database server. Although no specific vendor or product details beyond SEMCMS Shop v1.1 are provided, the vulnerability's presence in a web-based e-commerce platform suggests that online retail environments using this software are at risk. No patches or known exploits in the wild have been reported as of the publication date, but the critical nature of this vulnerability demands immediate attention to prevent potential exploitation. The lack of vendor or product details limits the scope of direct mitigation guidance, but standard SQL Injection defenses remain applicable.

For European organizations, the impact of this vulnerability could be severe, especially for small to medium-sized enterprises operating online stores using SEMCMS Shop or similar vulnerable platforms. Exploitation could lead to unauthorized access to customer data, including personal and payment information, violating GDPR and other data protection regulations, resulting in legal penalties and reputational damage. The integrity of transaction records and inventory data could be compromised, disrupting business operations and causing financial losses. Additionally, attackers could leverage the vulnerability to pivot into internal networks, escalating the threat to broader IT infrastructure. The criticality of the vulnerability and the ease of exploitation without authentication make it a significant risk to e-commerce businesses in Europe, where online retail is a substantial sector. Organizations may also face increased scrutiny from regulators and customers if breaches occur due to unpatched vulnerabilities.

Given the absence of official patches, European organizations should implement immediate compensating controls. These include deploying Web Application Firewalls (WAFs) configured to detect and block SQL Injection attempts targeting Ant_Global.php or similar endpoints. Input validation and sanitization should be enforced at the application level, employing parameterized queries or prepared statements to prevent injection. Organizations should conduct thorough code reviews and penetration testing focused on SQL Injection vectors. Monitoring and logging of database queries and web server access should be enhanced to detect suspicious activity early. If possible, isolate the vulnerable application in a segmented network zone to limit lateral movement in case of compromise. Organizations should also engage with the software vendor or community to obtain updates or patches and plan for timely application once available. Finally, regular backups of databases and application data should be maintained to enable recovery from potential data corruption or deletion.
