Das Parking Management System 6.2.0 SQL Injection Vulnerability (CVE-2026-9552)

A SQL injection vulnerability, identified as CVE-2026-9552, has been discovered in Das Parking Management System 停车场管理系统 version 6.2.0. This flaw resides within the Search API Endpoint, where the ‘Value’ argument is susceptible to manipulation. Successful exploitation allows a remote attacker to inject and execute arbitrary SQL commands. According to the NVD, a public exploit is available, increasing the risk of active exploitation. The vendor was notified but has not responded. This vulnerability poses a significant risk to organizations using the affected parking management system, potentially leading to data breaches, unauthorized access, and system compromise.

Attack Chain

1. Attacker identifies the Search API Endpoint within the Das Parking Management System 6.2.0.
2. Attacker crafts a malicious SQL payload designed to extract sensitive information or modify the database.
3. Attacker injects the SQL payload into the ‘Value’ argument of the Search API request.
4. The application fails to properly sanitize or validate the input.
5. The injected SQL code is executed against the database.
6. The attacker gains access to sensitive data, such as user credentials, financial records, or system configurations.
7. The attacker may use the extracted data for further malicious activities, such as unauthorized access to the system or data exfiltration.
8. Attacker achieves persistent access or control over the parking management system, potentially impacting operations.

Impact

Successful exploitation of this SQL injection vulnerability (CVE-2026-9552) in Das Parking Management System 6.2.0 can lead to unauthorized access to sensitive data, including user credentials, financial records, and system configurations. Given that a public exploit exists, organizations using this software are at high risk of data breaches, financial loss, and operational disruption. The lack of vendor response further exacerbates the risk, as no official patch or mitigation is available.

Recommendation

• Apply input validation and sanitization to the ‘Value’ argument in the Search API Endpoint to prevent SQL injection attacks targeting CVE-2026-9552.
• Deploy the Sigma rule Detect SQL Injection in Das Parking Management System to identify potential exploitation attempts against the Search API Endpoint.
• Monitor web server logs for suspicious requests containing SQL syntax in the ‘Value’ parameter as described in the attack chain.
• Review and restrict database user privileges to minimize the impact of successful SQL injection attacks.
• Implement a web application firewall (WAF) rule to filter out malicious SQL payloads in HTTP requests.
• Consider isolating the affected system from critical internal networks to limit the potential damage from a successful breach.
