CVE-2026-55985 in TPDIN-Monitor-WEB2
Summary
by MITRE • 07/25/2026
The web management interface in Tycon Systems TPDIN-Monitor-WEB2
stores and displays system credentials in cleartext on a certain configuration page accessible to authenticated users. Any party with access to the administrative dashboard can immediately read these credentials, which may be used to compromise other systems on the local network.

The vulnerability present in Tycon Systems TPDIN-Monitor-WEB2 represents a critical security flaw involving the improper handling of sensitive authentication data within the web management interface. This issue manifests as cleartext storage and display of system credentials on a specific configuration page that remains accessible to authenticated users, creating an inherent risk that directly contradicts fundamental security principles for credential protection. The flaw exists at the application level where sensitive information should be encrypted both at rest and in transit, yet the system fails to implement proper encryption mechanisms for stored credentials.
This technical vulnerability falls under the category of CWE-312 Cleartext Storage of Sensitive Information, which specifically addresses the insecure storage of sensitive data in an unencrypted format. The flaw enables unauthorized access to authentication credentials through legitimate administrative access paths, creating a privilege escalation scenario where authenticated users can directly retrieve system credentials without requiring additional exploitation techniques. From an operational perspective, this vulnerability significantly reduces the security posture of the affected system by providing attackers with immediate access to credentials that could potentially be used to compromise other networked systems within the local network environment.
The impact of this vulnerability extends beyond simple credential theft, as it creates a potential attack vector for lateral movement within the network infrastructure. When legitimate administrative users can view stored credentials in cleartext, they inadvertently provide attackers with the means to establish unauthorized access to additional systems that may share similar authentication mechanisms or credentials. This scenario aligns with ATT&CK technique T1563.002 for credential access through remote services and represents a significant risk to network segmentation and overall security architecture.
Mitigation strategies should focus on implementing proper encryption mechanisms for all stored credentials, ensuring that sensitive information is never stored or displayed in cleartext format. The system should enforce strong access controls that limit credential visibility to only those users who absolutely require such information for their specific administrative functions. Additionally, the implementation of role-based access control and principle of least privilege principles would help reduce the scope of potential credential exposure. Security patches should address the core issue by encrypting credentials at rest and implementing proper input validation and output sanitization techniques to prevent cleartext display of sensitive information. Network segmentation strategies and monitoring solutions should also be deployed to detect unauthorized access attempts to administrative interfaces and credential storage areas, providing additional layers of defense against exploitation of this vulnerability.
