RealSystem G2 server stores the administrator password in cleartext in a world-readable configuration file, which allows local users to gain privileges.
RealSystem G2 servers are vulnerable to a critical security flaw where the administrator password is stored in plaintext within a publicly accessible configuration file. This allows any local user to easily obtain the administrator password and gain unauthorized access, potentially leading to complete system compromise and data breaches.
Step 1: Access the Configuration File: A local user gains access to the server. Step 2: Identify the Configuration File: The user identifies the specific configuration file containing the administrator password. This is likely documented in public advisories or through basic reconnaissance. Step 3: Read the Configuration File: The user reads the contents of the configuration file, which is world-readable. Step 4: Extract the Password: The user extracts the administrator password from the plain text within the configuration file. Step 5: Gain Administrator Privileges: The user uses the extracted password to log in as the administrator, gaining full control of the RealSystem G2 server.
The vulnerability stems from a fundamental design flaw in the RealSystem G2 server's configuration management. The server, likely due to inadequate security practices, stores the administrator's password in a plain text format within a configuration file. This file is then assigned world-readable permissions, meaning any user with local access to the server can read its contents. The root cause is the lack of password hashing and encryption for sensitive data, coupled with insecure file permissions. The developers failed to implement basic security principles, leaving the system open to trivial exploitation. This highlights a severe lack of secure coding practices and a failure to protect sensitive credentials.
Due to the age of the vulnerability, it's unlikely to be directly associated with specific APT groups. However, any threat actor seeking to compromise legacy systems would likely leverage this vulnerability. This vulnerability is not listed on the CISA KEV list due to its age and the likely lack of active exploitation in modern environments, but it is still a critical risk if found in an environment.
Monitor file system access logs for access to configuration files associated with RealSystem G2 (e.g., files with names like 'realconfig.ini' or similar).
Analyze system logs for failed login attempts using the administrator account, which could indicate attempts to brute-force the password or use a compromised password.
Network traffic analysis for any unusual activity originating from the RealSystem G2 server, especially if it involves administrative protocols or data exfiltration.
Use file integrity monitoring tools to detect changes to the configuration files.
Employ a vulnerability scanner to identify vulnerable RealSystem G2 installations.
Immediately upgrade or replace the RealSystem G2 server with a supported and secure alternative. This is the most effective solution.
If upgrading or replacing is not immediately possible, isolate the vulnerable server from the network to limit exposure.
Implement strong access controls to the server, restricting local user access.
If access is unavoidable, review and change the administrator password to a strong, unique password.
Implement file system monitoring to detect unauthorized access to configuration files.
Review and harden the server's operating system security configuration.
Implement a security information and event management (SIEM) system to monitor logs and detect suspicious activity.
