CVE-2007-4124 in Ucosminexus Developer
Summary
by MITRE
The session failover function in Cosminexus Component Container in Cosminexus 6, 6.7, and 7 before 20070731, as used in multiple Hitachi products, can use session data for the wrong user under unspecified conditions, which might allow remote authenticated users to obtain sensitive information, corrupt another user s session data, and possibly gain privileges.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The vulnerability identified as CVE-2007-4124 affects the session failover functionality within the Cosminexus Component Container version 6, 6.7, and 7 prior to 20070731. This flaw exists in multiple Hitachi products and represents a critical security weakness in session management mechanisms. The issue stems from improper handling of session data during failover operations when system components transition between primary and backup states. The vulnerability manifests when session data intended for one user becomes accessible or usable by another user under unspecified conditions, creating a significant risk for unauthorized information access and session manipulation. The affected system architecture relies on Cosminexus Component Container for session management and failover processes, making it susceptible to cross-user session contamination during system transitions. This weakness is particularly concerning because it can enable authenticated attackers to exploit session data from other users, potentially leading to privilege escalation and unauthorized access to sensitive information.
The technical flaw involves the session failover mechanism failing to properly validate or isolate session data during system transitions, resulting in session data leakage between users. When a failover occurs, the system should ensure that session information remains properly associated with the correct user context, but in this case, the validation process is insufficient to prevent cross-contamination of session data. The vulnerability operates at the application layer and affects the session management subsystem within the Cosminexus Component Container, which is responsible for maintaining user session state and ensuring proper failover procedures. This issue can be categorized under CWE-200, which deals with improper information exposure, and CWE-284, relating to improper access control. The flaw allows for session hijacking and data corruption scenarios where an attacker can manipulate session tokens or data to impersonate other users or gain unauthorized access to their session information. The specific conditions under which this vulnerability manifests are not fully disclosed, but they likely involve timing issues during failover operations or inadequate session validation procedures.
The operational impact of this vulnerability extends beyond simple information disclosure to encompass potential privilege escalation and session data corruption. Remote authenticated users can exploit this weakness to access sensitive information belonging to other users, which may include personal data, business information, or system credentials. The session data corruption aspect poses a significant risk to system integrity, as attackers could manipulate another user's session state to gain unauthorized access to system resources or perform actions on behalf of other users. This vulnerability directly impacts the confidentiality, integrity, and availability of the affected Hitachi products, as it undermines the fundamental security assumptions of user session isolation. The implications are particularly severe in enterprise environments where multiple users interact with the same systems, as the vulnerability could enable widespread unauthorized access. The attack surface is broad given that multiple Hitachi products utilize this component container, making the vulnerability potentially exploitable across various system configurations.
Mitigation strategies for CVE-2007-4124 should focus on immediate patching of affected Cosminexus Component Container versions, specifically implementing the security updates released by Hitachi before 20070731. Organizations should implement additional monitoring of session failover operations to detect anomalous behavior that might indicate exploitation attempts. Network segmentation and access controls should be strengthened to limit the scope of potential exploitation, particularly in environments where multiple users share the same system resources. The implementation of robust session validation mechanisms and proper session isolation during failover operations is essential. Security teams should also consider implementing session tracking and auditing procedures to detect unauthorized session access patterns. From an ATT&CK framework perspective, this vulnerability aligns with techniques such as T1566 for credential access and T1078 for valid accounts, as attackers can leverage compromised session data to maintain persistent access. Organizations should also review their session management policies and ensure that session timeouts and invalidation procedures are properly implemented to minimize the window of opportunity for exploitation. Regular security assessments of session management components should be conducted to identify similar vulnerabilities in other system components.
