What is CVE-2024-58385?

Yonyou U8 CRM is susceptible to an unauthenticated SQL injection vulnerability located in the fillbacksettingedit.php configuration endpoint. By manipulating the DontCheckLogin=1 parameter, attackers can bypass authentication. This flaw allows the id parameter to be used in SQL queries without adequate sanitization, enabling malicious actors to execute arbitrary SQL commands. Furthermore, if the Microsoft SQL Server deployment has xp_cmdshell enabled, this vulnerability can also be leveraged to write backdoor files and execute arbitrary operating system commands, posing a significant risk to the integrity and confidentiality of the system.
