CVE-2025-6768: sfturing hosp_order SQL Injection Vulnerability

CVE-2025-6768 Overview

CVE-2025-6768 is a SQL injection vulnerability in the sfturing/hosp_order project, a hospital ordering application distributed on GitHub. The flaw resides in the findAllHosByCondition function within HospitalServiceImpl.java. An attacker can manipulate the hospitalName argument to inject arbitrary SQL into the backend query. The attack is executable remotely and requires only low-privilege authentication. Public exploit details have been disclosed through VulDB and the project's GitHub issue tracker. Because the project uses continuous delivery with rolling releases, no fixed version has been published, and all commits up to 627f426331da8086ce8fff2017d65b1ddef384f8 are affected.

Critical Impact
Remote attackers with low-level authentication can inject SQL statements through the hospitalName parameter, exposing hospital order data to unauthorized read, modification, or deletion.

Technical Details for CVE-2025-6768

Vulnerability Analysis

The vulnerability is a classic SQL injection flaw categorized under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The findAllHosByCondition method in HospitalServiceImpl.java accepts the hospitalName request parameter and incorporates it into a SQL query without proper parameterization or sanitization. An authenticated remote attacker can supply crafted input that alters the structure of the query. Successful exploitation permits unauthorized data retrieval, limited data modification, and potential disruption of query execution against the hospital order database.

Root Cause

The root cause is string concatenation of user-controlled input into a dynamic SQL statement within the service layer. The hospitalName argument is passed from the controller to the data access layer without binding to a prepared statement placeholder. Any SQL metacharacters supplied by the caller are interpreted by the database engine as part of the query.

Attack Vector

Exploitation requires network access to the application endpoint that invokes findAllHosByCondition and valid low-privilege credentials. The attacker submits a crafted hospitalName value containing SQL syntax such as boolean conditions, UNION clauses, or stacked queries. The backend database then executes the attacker-controlled query fragment. No user interaction is required beyond submitting the malicious request. Public proof-of-concept details are referenced in the GitHub Issue Discussion and VulDB #314082.

Detection Methods for CVE-2025-6768

Indicators of Compromise

HTTP requests to hospital search endpoints containing SQL metacharacters such as ', --, UNION SELECT, or OR 1=1 in the hospitalName parameter.
Database error messages or stack traces referencing HospitalServiceImpl.findAllHosByCondition in application logs.
Unexpected query execution time or result set sizes on hospital-related tables.

Detection Strategies

Instrument the application with a web application firewall (WAF) rule that inspects the hospitalName parameter for SQL injection patterns.
Enable database audit logging to capture queries originating from the findAllHosByCondition code path and alert on anomalous syntax.
Review authentication logs for low-privilege accounts issuing high volumes of search requests.

Monitoring Recommendations

Correlate web server access logs with database query logs to identify injected payloads reaching the backend.
Monitor outbound data volumes from the hospital order database for signs of bulk extraction.
Track application exceptions tied to malformed SQL to surface failed exploitation attempts.

How to Mitigate CVE-2025-6768

Immediate Actions Required

Restrict network access to the hosp_order application to trusted users and internal networks until a patched build is deployed.
Rotate credentials used by the application database account and apply least-privilege permissions on hospital tables.
Deploy WAF signatures that block SQL injection payloads targeting the hospitalName parameter.

Patch Information

No officially versioned patch is available. The maintainer uses continuous delivery with rolling releases, so administrators must track the upstream repository and rebuild from a commit newer than 627f426331da8086ce8fff2017d65b1ddef384f8 that remediates findAllHosByCondition. Refer to the GitHub Issue Discussion for maintainer updates.

Workarounds

Modify findAllHosByCondition to use parameterized queries or MyBatis #{} placeholders instead of string concatenation with ${} or raw append.
Add server-side input validation that rejects SQL metacharacters in the hospitalName parameter before it reaches the service layer.
Revoke DROP, ALTER, and write permissions from the database account used by the application where business logic allows read-only access.

bash

# Example: enforce least privilege on the MySQL account used by hosp_order
REVOKE ALL PRIVILEGES ON hosp_order.* FROM 'hosp_app'@'%';
GRANT SELECT ON hosp_order.hospital TO 'hosp_app'@'%';
FLUSH PRIVILEGES;
