CVE-2025-34162 in Bian Que Feijiu Intelligent Emergency and Quality Control System
Summary
by MITRE • 08/28/2025
An unauthenticated SQL injection vulnerability exists in the GetLyfsByParams endpoint of Bian Que Feijiu Intelligent Emergency and Quality Control System, accessible via the /AppService/BQMedical/WebServiceForFirstaidApp.asmx interface. The backend fails to properly sanitize user-supplied input in the strOpid parameter, allowing attackers to inject arbitrary SQL statements. This can lead to data exfiltration, authentication bypass, and potentially remote code execution, depending on backend configuration. The vulnerability is presumed to affect builds released prior to June 2025 and is remediated in newer versions of the product, though the exact affected range remains undefined. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-07-23 UTC.

The vulnerability identified as CVE-2025-34162 represents a critical security flaw within the Bian Que Feijiu Intelligent Emergency and Quality Control System, specifically targeting the GetLyfsByParams endpoint exposed through the /AppService/BQMedical/WebServiceForFirstaidApp.asmx interface. This system serves as a medical emergency and quality control platform that processes sensitive healthcare data, making the presence of such a vulnerability particularly concerning from both security and compliance perspectives. The vulnerability manifests as an unauthenticated SQL injection weakness that directly impacts the system's ability to process user input securely.
The technical flaw resides in the improper sanitization of the strOpid parameter within the GetLyfsByParams endpoint, where the backend application fails to adequately validate or escape user-supplied input before incorporating it into SQL query constructs. This parameter processing failure creates an exploitable entry point that allows attackers to craft malicious SQL statements that bypass normal input validation mechanisms. The vulnerability operates at the application layer and can be exploited without requiring authentication credentials, significantly expanding the attack surface and reducing the barriers for potential exploitation. According to established cybersecurity frameworks, this vulnerability maps directly to CWE-89, which specifically addresses SQL injection flaws where insufficient input validation allows malicious SQL code execution.
The operational impact of this vulnerability extends beyond simple data access violations and encompasses several critical security implications that could severely compromise the integrity and confidentiality of the affected system. Attackers could potentially exfiltrate sensitive patient medical records, manipulate quality control data, and bypass authentication mechanisms to gain unauthorized access to system functionalities. In environments where the backend database configuration permits certain privileges, this vulnerability could potentially lead to remote code execution, transforming the SQL injection into a more severe compromise that could allow attackers to execute arbitrary commands on the affected system. The vulnerability's scope appears to be limited to systems deployed prior to June 2025, indicating that the manufacturer has recognized and addressed this issue in subsequent releases, though the exact vulnerable version range remains unspecified.
Organizations utilizing this system should immediately implement comprehensive mitigations to address the identified vulnerability, beginning with the urgent deployment of the latest available patches from the vendor. Network segmentation and access control measures should be enhanced to limit exposure of the vulnerable endpoint to unauthorized users, while implementing robust input validation at multiple layers of the application architecture. Database administrators should review and restrict database user privileges to minimize potential damage from successful exploitation attempts. The remediation process should include thorough testing to ensure that the patch does not introduce regressions in system functionality while maintaining compliance with healthcare data protection regulations such as HIPAA and GDPR. Additionally, implementing web application firewalls and intrusion detection systems can provide additional layers of protection against exploitation attempts, while continuous monitoring and logging of database access patterns can help detect potential abuse of this vulnerability. The vulnerability's classification under ATT&CK framework category T1190 - Exploit Public-Facing Application aligns with the typical exploitation patterns for unauthenticated SQL injection flaws, emphasizing the need for proper application hardening and regular security assessments to prevent similar vulnerabilities from emerging in other system components.
