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.

Executive Summary

This is an unauthenticated SQL injection vulnerability in Yonyou U8 CRM's fillbacksettingedit.php endpoint. The DontCheckLogin=1 parameter bypasses authentication, and the id parameter is used in SQL queries without sanitization. Attackers can execute arbitrary SQL commands and, if xp_cmdshell is enabled on Microsoft SQL Server, write backdoor files and run OS commands.

Detection Guidance

To detect this vulnerability, check if the fillbacksettingedit.php endpoint is accessible without authentication. Use tools like curl to send a test request with the DontCheckLogin=1 parameter. Example: curl -v 'http://target.com/config/fillbacksettingedit.php?id=1&DontCheckLogin=1'. If the server responds without requiring login, the endpoint is vulnerable.

Impact Analysis

If exploited, attackers can gain unauthorized access to sensitive data, manipulate or delete database records, and execute system-level commands on the server. This could lead to data breaches, system compromise, or full control over the affected server.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Non-compliance may result in legal penalties, fines, or reputational damage.

Mitigation Strategies
  • Apply the official patch from Yonyou (U8CRM存在SQL注ε…₯ζΌζ΄žε―Όθ‡΄RCEηš„θ‘₯丁20240925.zip) and overwrite the installation directory.
  • Restrict access to the fillbacksettingedit.php endpoint by adding Require local in the Apache configuration file.
  • Disable unnecessary services like Apache4TurboCRM70, TurboCRM70, and memcached Server if using older versions (V16.1 or below) without CRM functionality.
  • Ensure xp_cmdshell is disabled on Microsoft SQL Server deployments to prevent command execution.
