CWE ID Description
CWE-89 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.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

This is a SQL injection vulnerability in Jinher OA C6 software. It affects the ProjID parameter in the file /C6/JHSoft.Web.Project/OfficeReadOnly/ProjectAfficheManage.aspx. The vulnerability allows attackers to inject malicious SQL commands into the application due to improper input sanitization. The exploit can be performed remotely without authentication.

Detection Guidance

To detect this SQL injection vulnerability in Jinher OA C6, monitor HTTP GET requests targeting the /C6/JHSoft.Web.Project/OfficeReadOnly/ProjectAfficheManage.aspx endpoint with the ProjID parameter. Look for unusual or malformed input values in ProjID that may indicate SQL injection attempts, such as single quotes, semicolons, or SQL keywords like UNION, SELECT, or DROP.

  • Use tools like SQLmap to test for SQL injection by sending crafted requests to the ProjID parameter: sqlmap -u "http://target/C6/JHSoft.Web.Project/OfficeReadOnly/ProjectAfficheManage.aspx?ProjID=1" --batch --dbs.
  • Inspect web server logs for suspicious patterns in the ProjID parameter, such as repeated failed requests or requests containing SQL syntax.
Impact Analysis

This vulnerability can lead to unauthorized access to sensitive data, privilege escalation, remote code execution, and complete system compromise. Attackers can exploit it via crafted HTTP GET requests to manipulate the database backend, which is Microsoft SQL Server.

Compliance Impact

This SQL injection vulnerability could lead to unauthorized access to sensitive data, which directly impacts compliance with GDPR (data protection) and HIPAA (healthcare data privacy). Unauthorized access risks violating confidentiality requirements and may result in regulatory penalties due to data breaches.

Mitigation Strategies

Immediately apply input validation and sanitization for the ProjID parameter to reject any non-numeric or malformed input. Implement parameterized queries in the application to prevent SQL injection. Ensure the database user has least privileges and cannot execute administrative commands.

  • Deploy a web application firewall (WAF) to filter malicious requests targeting the ProjID parameter.
  • Update Jinher OA C6 to the latest version if a patch is available. If no patch exists, consider isolating the affected component or migrating to a different solution.
