CVE-2007-2638 in eFileCabinet
Summary
by MITRE
eFileCabinet 3.3 allows remote attackers to bypass authentication and access restricted portions of the interface via an invalid filecabinetnumber, which can be leveraged to obtain sensitive information or create new data structures.

The vulnerability identified as CVE-2007-2638 affects eFileCabinet version 3.3, a document management system that provides electronic file cabinet functionality for organizations. This authentication bypass flaw represents a critical security weakness that undermines the fundamental access control mechanisms of the application. The vulnerability specifically manifests when the system processes an invalid filecabinetnumber parameter, allowing unauthorized users to circumvent the normal authentication procedures and gain access to restricted administrative interfaces.
The technical implementation of this vulnerability stems from insufficient input validation and improper session management within the eFileCabinet application. When an attacker submits an invalid filecabinetnumber, the system fails to properly validate the parameter and instead processes the request with elevated privileges or without proper authentication checks. This flaw falls under CWE-287 which addresses improper authentication issues, and specifically aligns with the ATT&CK technique T1078 for valid accounts and T1566 for credential harvesting through social engineering or system exploitation. The vulnerability exists because the application does not adequately sanitize or verify the filecabinetnumber parameter before proceeding with access control decisions.
The operational impact of this vulnerability extends beyond simple unauthorized access, creating significant risks for organizations using eFileCabinet 3.3. Attackers can leverage this flaw to obtain sensitive information stored within the system, including confidential documents, user data, and system configurations. Additionally, the vulnerability enables malicious actors to create new data structures, potentially leading to data corruption, unauthorized modifications, or even complete system compromise. Organizations may face regulatory compliance violations, data breaches, and reputational damage when such vulnerabilities exist in their document management infrastructure. The risk is particularly severe because the authentication bypass can be achieved remotely without requiring prior knowledge of valid credentials.
Mitigation strategies for this vulnerability should include immediate patching of the eFileCabinet application to version 3.4 or later, which contains the necessary fixes for the authentication bypass issue. Organizations should also implement network segmentation to limit access to the eFileCabinet system, deploy intrusion detection systems to monitor for suspicious parameter manipulation attempts, and establish robust input validation controls. The implementation of proper access control mechanisms, including multi-factor authentication and role-based access controls, can help reduce the impact of such vulnerabilities. Security teams should conduct regular vulnerability assessments and penetration testing to identify similar authentication bypass issues in other enterprise applications, particularly those handling sensitive data. Organizations should also consider implementing web application firewalls to filter malicious requests targeting parameter manipulation vulnerabilities.
