A hardcoded password vulnerability has been found in CENTUM. Affected products contain a hardcoded password for the user account (PROG) used for CENTUM Authentication Mode within the system. This vulnerability allows an attacker to potentially log in as the PROG user under certain conditions.
The default permission for PROG users is S1 permission (equivalent to OFFUSER). Therefore, for properly permission-controlled targets of operation and monitoring, even if an attacker logs in as the PROG user, the risk of critical operations or configuration changes being performed is considered low. However, if the PROG user's permissions have been altered, there is a risk that operations or configuration changes may occur under those modified permissions.
Exploiting this vulnerability requires the attacker to already have access to the HIS screen controls. Thus, an attacker can operate and monitor at that point, regardless of this vulnerability.
The affected products and versions include CENTUM VP R5.01.00 to R5.04.20, R6.01.00 to R6.12.00, and R7.01.00. Organizations should be aware of this vulnerability and take necessary steps to mitigate the risks.
Vulnerability Details
The hardcoded password vulnerability in CENTUM is classified as a low severity issue, with a CVSS score of 2.1. The attack vector is local, and the attack complexity is high, requiring specific conditions to be met for exploitation.
The vulnerability is linked to CWE-259, which relates to hard-coded passwords. Organizations should evaluate the configurations of their CENTUM installations to ensure they are not exposed to unnecessary risks.
Technical Analysis
The root cause of this vulnerability is the presence of hardcoded credentials within the CENTUM system. This presents a potential risk if an attacker discovers the hardcoded password through various means.
The attack vector is local, meaning an attacker needs to have physical or remote access to the system to exploit this vulnerability. The attack complexity is high, as it requires specific knowledge and access to the HIS system, along with the ability to perform screen operations.
No privileges are required to exploit this vulnerability, and user interaction is not necessary. The impacts on confidentiality and integrity are low, while availability is unaffected.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access under specific conditions. Given the low CVSS score and the nature of the permissions associated with the PROG user, the urgency for remediation is low, allowing organizations to address it in their routine maintenance cycles.
However, organizations should remain vigilant and ensure that they have properly configured access controls to minimize any risk associated with this vulnerability. The blast radius is limited due to the required conditions for exploitation.

Mitigation & Remediation
Organizations should apply available patches for CENTUM products to address this hardcoded password vulnerability. If immediate patching is not possible, implementing configuration hardening and ensuring robust access controls can help mitigate potential risks.
For further guidance, organizations may consider engaging in penetration testing to evaluate their security posture.
Detection Guidance
Organizations should monitor logs for any unauthorized access attempts and operational anomalies related to the CENTUM system. Additionally, behavioral anomalies that may indicate exploitation attempts should be tracked.
