In this long read, we dive deep into the CVE-2022-41157 vulnerability found within the Kyungrinara Enterprise Resource Planning (ERP) system, specifically affecting the sERP server. This vulnerability was discovered in a particular file of the server where a fixed password with the SYSTEM authority is used. This could potentially allow malicious attackers to steal sensitive information, execute harmful commands, or possibly cause irreversible damage to the system.

This alarming vulnerability warrants immediate attention to prevent any exploitation and ensure the security of Kyungrinara's ERP solution users.

2. Severity of CVE-2022-41157

This vulnerability is rated critical and poses a significant threat to organizations relying on the affected Kyungrinara ERP system. An attacker who obtains the fixed SYSTEM password can potentially:

Deploy malware or ransomware to disrupt business processes

As a result, this vulnerability not only exposes sensitive data, but also puts an organization's reputation, financial stability, and legal compliance at risk.

The code snippet below illustrates the vulnerability present in the sERP server file

public class SensitiveFile
{
    private static final String SYSTEM_AUTHORITY_PASSWORD = "fixed_password_here"; // This should not be a fixed, hardcoded password!

    public void authenticateAndExecute(String userPassword, String command)
    {
        if (userPassword.equals(SYSTEM_AUTHORITY_PASSWORD))
        {
            // Execute the privileged command
            executeSystemCommand(command);
        }
        else
        {
            // Deny access
            System.out.println("Access denied. Incorrect password.");
        }
    }

    private void executeSystemCommand(String command)
    {
        // Logic to execute the command with SYSTEM privileges
    }
}

As seen above, the SYSTEM_AUTHORITY_PASSWORD is hardcoded within the class. This allows for easy retrieval and exploitation by an attacker.
