CVE-2018-18006 in myPrint
Summary
by MITRE
Hardcoded credentials in the Ricoh myPrint application 2.9.2.4 for Windows and 2.2.7 for Android give access to any externally disclosed myPrint WSDL API, as demonstrated by discovering API secrets of related Google cloud printers, encrypted passwords of mail servers, and names of printed files.

The vulnerability identified as CVE-2018-18006 represents a critical security flaw in Ricoh myPrint applications across both Windows and Android platforms. This issue stems from the improper handling of authentication credentials within the application's codebase, where hardcoded secrets and passwords are embedded directly into the software rather than being dynamically retrieved or securely managed. The vulnerability affects specific versions including myPrint 2.9.2.4 for Windows and 2.2.7 for Android, creating a persistent security risk that extends beyond the local device to impact cloud-based services and external network resources.
The technical implementation of this flaw manifests through the inclusion of hardcoded API keys, passwords, and authentication tokens within the application binaries. When these credentials are embedded directly in the source code or configuration files, they become permanently accessible to anyone who can obtain the application package or analyze its memory structures. This practice violates fundamental security principles and creates an attack surface that allows malicious actors to gain unauthorized access to connected services. The vulnerability specifically impacts the myPrint WSDL API endpoints, which serve as the communication interface between the printing application and various backend services including Google Cloud Print services and mail server configurations.
The operational impact of this vulnerability extends far beyond simple unauthorized access, as it enables attackers to compromise multiple system components simultaneously. Security researchers demonstrated that the hardcoded credentials could be used to access Google cloud printer API secrets, which would allow unauthorized printing operations to be performed on behalf of legitimate users. Additionally, the vulnerability exposes encrypted passwords for mail servers, potentially enabling attackers to intercept email communications or perform unauthorized actions through email-based authentication systems. The exposure of printed file names creates additional privacy concerns, as sensitive document information becomes accessible to unauthorized parties. This multi-faceted impact aligns with CWE-798 standards for insecure storage of credentials and represents a significant weakness in the application's security architecture.
Organizations and users affected by this vulnerability face substantial risk exposure, particularly in enterprise environments where printing services integrate with cloud infrastructure and sensitive data processing systems. The hardcoded nature of these credentials means that even if users change their passwords or update service configurations, the embedded secrets remain valid and functional. This creates a persistent threat vector that can be exploited for extended periods without detection, potentially leading to data breaches, unauthorized printing activities, and privacy violations. The vulnerability also demonstrates the importance of secure coding practices and proper credential management, as outlined in NIST SP 800-63B standards for authentication and trust services. The attack surface created by this flaw enables adversaries to perform reconnaissance activities and establish persistent access to network resources, potentially facilitating further exploitation through lateral movement and privilege escalation techniques.
Mitigation strategies should focus on immediate remediation through application updates from Ricoh, which would involve removing hardcoded credentials and implementing proper dynamic credential retrieval mechanisms. Organizations must also conduct comprehensive security assessments to identify any other applications or systems that may contain similar hardcoded credentials. Network segmentation and monitoring controls should be implemented to detect unauthorized access attempts to cloud services and API endpoints. The vulnerability highlights the necessity of following secure development lifecycle practices, including code reviews for credential handling, secure configuration management, and regular security testing. Additionally, implementing automated credential rotation systems and service account management protocols would help prevent similar issues from occurring in future deployments. This vulnerability serves as a reminder of the critical importance of proper authentication management and the dangers of hardcoding sensitive information within application code, as referenced in the ATT&CK framework's credential access techniques and the broader security community's emphasis on secure coding practices.
