CVE-2014-4875 in CHEC
Summary
by MITRE
CreateBossCredentials.jar in Toshiba CHEC before 6.6 build 4014 and 6.7 before build 4329 contains a hardcoded AES key, which allows attackers to discover Back Office System Server (BOSS) DB2 database credentials by leveraging knowledge of this key in conjunction with bossinfo.pro read access.

The vulnerability identified as CVE-2014-4875 represents a critical security flaw in Toshiba CHEC software versions prior to specific build numbers. This issue resides within the CreateBossCredentials.jar component which is part of the Toshiba CHEC system architecture designed for enterprise database management and back office operations. The vulnerability stems from the inclusion of a hardcoded Advanced Encryption Standard key within the jar file, creating a fundamental weakness in the cryptographic implementation that directly impacts database security. The presence of such a hardcoded key violates established security principles and creates a persistent attack vector that remains exploitable across multiple system deployments.
The technical implementation of this vulnerability involves a hardcoded AES encryption key embedded within the CreateBossCredentials.jar file, which is used to encrypt and decrypt database credentials for the Back Office System Server. Attackers who obtain read access to the bossinfo.pro configuration file can leverage this knowledge to reverse engineer the encryption process and extract sensitive database authentication information. This represents a classic case of weak cryptography implementation where the security of the entire system relies on a single hardcoded key rather than dynamic key generation or secure key management practices. The vulnerability creates a path for privilege escalation and unauthorized database access, as the encryption key serves as a bridge between the configuration file and the actual database credentials.
The operational impact of this vulnerability extends beyond simple credential theft, as it enables attackers to gain unauthorized access to critical enterprise database systems. The Back Office System Server database contains sensitive organizational data that could include financial records, customer information, and business-critical operational data. Successful exploitation allows attackers to perform unauthorized database queries, modify records, or extract confidential information, potentially leading to significant financial loss and regulatory compliance violations. This vulnerability particularly affects organizations using Toshiba CHEC systems for enterprise database management, where the compromise of database credentials can result in widespread data exposure and operational disruption. The impact is amplified by the fact that the hardcoded key remains consistent across multiple installations, making the vulnerability scalable and easy to exploit once discovered.
Mitigation strategies for this vulnerability require immediate remediation through software updates to Toshiba CHEC versions that address the hardcoded key issue. Organizations should implement comprehensive key management practices and avoid embedding cryptographic keys within application code. The recommended approach involves replacing hardcoded keys with dynamically generated encryption keys managed through secure key management systems and implementing proper access controls for configuration files. Security measures should include regular security assessments of third-party components, implementation of network segmentation to limit access to database systems, and monitoring for unauthorized access attempts. This vulnerability aligns with CWE-321: Use of Hard-coded Cryptographic Key and demonstrates the importance of following secure coding practices as outlined in NIST SP 800-57 and ISO/IEC 15408 standards. The attack vector corresponds to techniques described in MITRE ATT&CK framework under credential access and defense evasion categories, specifically targeting the exploitation of hardcoded credentials and weak encryption implementations.
