CVE-2014-2276 in Connectrix Manager
Summary
by MITRE
The FileUploadController servlet in EMC Connectrix Manager Converged Network Edition (CMCNE) before 12.1.5 does not properly restrict additions to the Connectrix Manager repository, which allows remote attackers to obtain sensitive information by importing a crafted firmware file.

The vulnerability identified as CVE-2014-2276 affects EMC Connectrix Manager Converged Network Edition (CMCNE) versions prior to 12.1.5, specifically within the FileUploadController servlet component. This issue represents a critical security flaw that undermines the integrity of the repository management system by failing to implement proper validation mechanisms for firmware file imports. The vulnerability exists in the web application's file handling logic where unauthorized file operations can be executed through the upload interface, creating a pathway for attackers to manipulate the system's repository contents.
The technical flaw manifests in the improper restriction of file additions to the Connectrix Manager repository, allowing attackers to import malicious or crafted firmware files that could contain sensitive information or malicious code. This vulnerability falls under CWE-434 which describes "Unrestricted Upload of File with Dangerous Type" and represents a classic insecure file upload vulnerability that enables arbitrary code execution or information disclosure. The flaw occurs because the application does not properly validate file types, content, or metadata during the upload process, permitting attackers to bypass normal access controls and repository restrictions.
Operationally, this vulnerability presents significant risks to organizations using EMC CMCNE systems, as remote attackers can exploit the weakness to gain unauthorized access to sensitive information stored within the repository. The impact extends beyond simple information disclosure to potentially enable more severe attacks including privilege escalation, system compromise, or data exfiltration. Attackers could leverage this vulnerability to import firmware files containing backdoors, malware, or other malicious payloads that could persist within the network infrastructure and provide long-term access to the compromised system.
The exploitation of this vulnerability aligns with several ATT&CK techniques including T1078 Valid Accounts for initial access, T1566 Phishing for initial compromise, and T1059 Command and Scripting Interpreter for executing malicious code. Organizations using affected versions of CMCNE should implement immediate mitigations including applying the vendor-provided patches, implementing proper file type validation, restricting upload permissions, and monitoring repository access logs for suspicious activities. Additionally, network segmentation and intrusion detection systems should be deployed to monitor for potential exploitation attempts and to contain any successful attacks within the network perimeter.
