CVE-2024-58385: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in Yonyou U8 CRM
Yonyou U8 CRM has an unauthenticated SQL injection vulnerability in the fillbacksettingedit.php endpoint. The vulnerability arises because the DontCheckLogin=1 parameter bypasses authentication and the id parameter is unsanitized in SQL queries. This allows attackers to execute arbitrary SQL commands. On Microsoft SQL Server deployments with xp_cmdshell enabled, attackers can write backdoor files and execute arbitrary OS commands. The vulnerability affects multiple versions of Yonyou U8 CRM and has a critical severity score of 9.3.
AI Analysis
Technical Summary
CVE-2024-58385 is an unauthenticated SQL injection vulnerability in Yonyou U8 CRM's fillbacksettingedit.php configuration endpoint. The DontCheckLogin=1 parameter bypasses authentication, and the id parameter is used without proper sanitization in SQL queries. This flaw enables attackers to execute arbitrary SQL commands. In environments using Microsoft SQL Server with xp_cmdshell enabled, attackers can escalate the impact by writing backdoor files and executing arbitrary operating system commands. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-02-13. The vulnerability affects versions 13, 15.1, 16.0, 16.1, 16.5, and 18 of Yonyou U8 CRM. The CVSS 4.0 base score is 9.3, indicating critical severity.
Potential Impact
Successful exploitation allows unauthenticated attackers to execute arbitrary SQL commands on the backend database. On Microsoft SQL Server deployments with xp_cmdshell enabled, attackers can write backdoor files and execute arbitrary operating system commands, potentially leading to full system compromise. This poses a critical risk to confidentiality, integrity, and availability of affected systems.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the vulnerable endpoint and disable xp_cmdshell on Microsoft SQL Server instances if enabled to reduce risk.
