CVE-2025-9669 Overview
A SQL injection vulnerability has been identified in Jinher OA version 1.0. This vulnerability exists in the GetTreeDate.aspx file, where improper handling of the ID parameter allows attackers to inject malicious SQL commands. The vulnerability can be exploited remotely over the network without authentication, potentially enabling unauthorized access to sensitive database information, data manipulation, or further compromise of the affected system.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially escalate to full system compromise through database server exploitation.
Affected Products
- Jinher OA 1.0
- jinher:jinher_oa component

Technical Details for CVE-2025-9669
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) occurs due to insufficient input validation in the GetTreeDate.aspx endpoint of Jinher OA. The ID parameter is directly incorporated into SQL queries without proper sanitization or parameterized query implementation. This allows an attacker to manipulate the query structure by injecting SQL syntax, potentially bypassing authentication, extracting database contents, or executing administrative operations on the underlying database server.
The vulnerability is classified under both CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output), indicating a fundamental failure in input validation and output encoding practices within the application.
Root Cause
The root cause of this vulnerability is the lack of proper input sanitization for the ID parameter in the GetTreeDate.aspx file. User-supplied input is directly concatenated into SQL queries rather than being processed through parameterized queries or prepared statements. This classic injection flaw allows attackers to escape the intended query context and inject arbitrary SQL commands.
Attack Vector
The attack can be conducted remotely over the network. An attacker can craft malicious HTTP requests to the GetTreeDate.aspx endpoint with specially crafted ID parameter values containing SQL injection payloads. Since no authentication is required and the attack complexity is low, this vulnerability presents a significant risk to any internet-exposed Jinher OA installations.
The exploitation technique involves manipulating the ID parameter to inject SQL commands. Common attack patterns include using UNION-based injection to extract data from other tables, boolean-based blind injection to infer database contents, or time-based blind injection when direct output is not available. Technical details and proof-of-concept information have been disclosed publicly through the GitHub CVE Issue Tracker.
Detection Methods for CVE-2025-9669
Indicators of Compromise
- Unusual or malformed requests to GetTreeDate.aspx containing SQL keywords such as UNION, SELECT, INSERT, UPDATE, DELETE, or comment sequences (--, /*)
- Web server logs showing requests with encoded SQL characters in the ID parameter (e.g., %27, %3B, %2D%2D)
- Database logs indicating failed queries, unusual query patterns, or queries accessing unexpected tables
- Unexpected database modifications or new administrative accounts
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to GetTreeDate.aspx
- Configure intrusion detection systems (IDS) to alert on HTTP requests containing common SQL injection payloads targeting the ID parameter
- Implement database activity monitoring to detect abnormal query patterns, excessive data extraction, or unauthorized schema queries
- Enable detailed logging on the Jinher OA application server and correlate with database audit logs
Monitoring Recommendations
- Monitor web server access logs for repeated requests to GetTreeDate.aspx with varying ID parameter values, which may indicate automated exploitation attempts
- Set up alerts for database errors that may indicate failed injection attempts
- Review network traffic for unusual outbound data transfers from the database server that could indicate data exfiltration
How to Mitigate CVE-2025-9669
Immediate Actions Required
- Restrict access to the GetTreeDate.aspx endpoint using network-level controls until a patch is available
- Implement input validation to block requests containing SQL injection patterns in the ID parameter
- Deploy WAF rules to filter malicious requests targeting this endpoint
- Consider taking the affected application offline if it is internet-facing and no compensating controls are available
Patch Information
No official vendor patch information is currently available for this vulnerability. Organizations should monitor Jinher's official channels for security updates. Additional technical details can be found in the following references:
Workarounds
- Implement strict input validation on the ID parameter to allow only expected numeric or alphanumeric values
- Use a reverse proxy or WAF to filter requests containing SQL injection payloads before they reach the application
- Restrict database user permissions for the Jinher OA application to limit the impact of successful exploitation
- Segment the network to limit attacker lateral movement if the database server is compromised
