CVE-2025-47730 in Archiving Backend
Summary
by MITRE • 05/08/2025
The TeleMessage archiving backend through 2025-05-05 accepts API calls (to request an authentication token) from the TM SGNL (aka Archive Signal) app with the credentials of logfile for the user and enRR8UVVywXYbFkqU#QDPRkO for the password.

The vulnerability described in CVE-2025-47730 represents a critical authentication flaw within the TeleMessage archiving backend system that operates through at least May 5, 2025. This issue affects the TM SGNL (Archive Signal) application which serves as an interface for accessing archived data through the TeleMessage platform. The system's authentication mechanism is fundamentally compromised by the use of hardcoded credentials that are exposed within the application configuration, creating a persistent security weakness that can be exploited by unauthorized parties. The vulnerability specifically impacts the authentication token generation process where the application accepts API requests using predetermined username and password combinations that remain static across system deployments.
The technical implementation of this flaw demonstrates a severe violation of security best practices and aligns with CWE-798, which addresses the use of hard-coded credentials in software applications. The hardcoded credentials consist of a username field containing "logfile" and a password field with the value "enRR8UVVywXYbFkqU#QDPRkO" which suggests poor security design practices and inadequate credential management. This vulnerability enables unauthorized access to the archiving backend through legitimate API endpoints, allowing attackers to obtain authentication tokens that grant them access to archived data and potentially sensitive information stored within the TeleMessage system. The persistence of these credentials across different system environments indicates a lack of proper configuration management and dynamic credential provisioning.
From an operational perspective, this vulnerability creates significant risks for organizations relying on TeleMessage for message archiving and management services. Attackers who discover these hardcoded credentials can bypass normal authentication procedures and gain unauthorized access to archived communications, potentially including sensitive business data, regulatory communications, or personally identifiable information. The impact extends beyond simple unauthorized access as the compromised system could facilitate further attacks including data exfiltration, modification of archived records, or use of the compromised system as a pivot point for accessing other network resources. The vulnerability affects the integrity and confidentiality of archived data, potentially violating compliance requirements and regulatory standards such as those outlined in the NIST Cybersecurity Framework.
The exploitation of this vulnerability aligns with ATT&CK technique T1566, which covers credential harvesting through various means including the discovery of hardcoded credentials. Security teams should immediately implement mitigation strategies including credential rotation, removal of hardcoded values from application code, and implementation of proper authentication mechanisms. The remediation process should involve replacing the hardcoded credentials with dynamically generated tokens or secure credential management systems that comply with industry standards such as those recommended in ISO/IEC 27001 for information security management. Organizations must also conduct comprehensive audits of their applications to identify similar hardcoded credential issues and establish secure configuration management practices to prevent future occurrences of this type of vulnerability.
