Glory RBG-100 recycler systems using the ISPK-08 software component contain hard-coded operating system credentials that allow remote authentication to the underlying Linux system. Multiple local user accounts, including accounts with administrative privileges, were found to have fixed, embedded passwords. An attacker with network access to exposed services such as SSH may authenticate using these credentials and gain unauthorized access to the system. Successful exploitation allows remote access with elevated privileges and may result in full system compromise.
Critical vulnerability discovered in Glory RBG-100 recycler systems, allowing remote, unauthorized access due to hard-coded credentials within the ISPK-08 software component. Successful exploitation grants attackers elevated privileges, potentially leading to complete system compromise and data exfiltration.
Step 1: Reconnaissance: An attacker identifies a target Glory RBG-100 recycler system with network access, potentially using port scanning (e.g., Nmap) to identify open services like SSH (port 22). Step 2: Credential Harvesting: The attacker researches the vulnerability and identifies the hard-coded credentials associated with the ISPK-08 software component. This information may be available through public advisories or vulnerability databases. Step 3: Authentication Attempt: The attacker uses the identified hard-coded credentials to attempt to authenticate to the target system via SSH or other exposed services. Step 4: Privilege Escalation (if applicable): If the attacker successfully authenticates with a low-privilege account, they may attempt to escalate their privileges to gain administrative access using known Linux privilege escalation techniques (e.g., exploiting misconfigured SUID binaries or kernel vulnerabilities). Step 5: System Compromise: Upon successful authentication with administrative credentials or privilege escalation, the attacker gains full control of the system, allowing them to access sensitive data, modify system configurations, and potentially deploy further malicious payloads.
The vulnerability stems from the insecure coding practice of embedding hard-coded credentials within the ISPK-08 software component. Specifically, multiple local user accounts, including those with administrative privileges, are configured with fixed, static passwords. This eliminates the need for any complex exploitation technique beyond basic authentication. The root cause is a failure to implement secure password management practices, such as using unique, randomly generated passwords and securely storing them (e.g., using a password manager or hashing with salting). The lack of proper security controls allows attackers to bypass authentication mechanisms and gain unauthorized access to the underlying Linux system.
This vulnerability is attractive to a wide range of threat actors, including financially motivated cybercriminals, state-sponsored actors, and hacktivists. The potential for disruption of financial services and data theft makes it a high-value target. CISA KEV status: Likely to be added quickly due to the ease of exploitation and high impact.
Monitor network traffic for SSH login attempts using known hard-coded credentials (e.g., using a network intrusion detection system - NIDS).
Analyze system logs (e.g., /var/log/auth.log) for successful SSH logins from unexpected IP addresses or with suspicious usernames.
Perform vulnerability scans using tools like Nessus or OpenVAS to identify vulnerable Glory RBG-100 systems.
Monitor for unusual file access or modification activity on the system, particularly in sensitive directories.
Implement file integrity monitoring to detect unauthorized changes to critical system files.
Immediately change the hard-coded passwords for all user accounts, ensuring strong, unique passwords are used.
Implement multi-factor authentication (MFA) for all remote access services, such as SSH.
Review and restrict network access to the recycler systems, limiting access to only authorized users and networks.
Update the ISPK-08 software component to a patched version that addresses the vulnerability (if available).
Implement a robust password management policy, including regular password changes and the use of a password manager.
Disable or restrict unnecessary services, such as SSH, if they are not required for normal operation.
Implement host-based intrusion detection systems (HIDS) to monitor for malicious activity on the system.
Conduct regular security audits and penetration testing to identify and address vulnerabilities.
