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 said to be 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 product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
