The vulnerability identified as CVE-2010-1941 represents a critical security flaw affecting NEC WebSAM DeploymentManager versions 5.13 and earlier, which are integrated into various NEC management platforms including SigmaSystemCenter 2.1 Update2 and earlier, BladeSystemCenter, ExpressSystemCenter, and VirtualPCCenter 2.2 and earlier. This vulnerability manifests as an unspecified weakness that enables remote attackers to execute denial of service attacks capable of triggering operating system shutdown or restart commands. The attack vector involves crafted packets transmitted to port 56010, which serves as the primary communication channel for Client Service for DPM components within these systems. The vulnerability exists within the protocol handling mechanisms of the DeploymentManager service, specifically in how it processes incoming network traffic destined for the designated port.
The technical implementation of this vulnerability stems from insufficient input validation and inadequate error handling within the Client Service for DPM functionality. When the system receives malformed or specially crafted packets on port 56010, the DeploymentManager service fails to properly sanitize the incoming data, leading to potential exploitation of buffer overflow conditions or command injection flaws. This weakness allows attackers to manipulate the service's behavior in ways that can result in system instability, immediate shutdown, or forced restart of the affected operating systems. The vulnerability's classification as unspecified suggests that the exact technical mechanism may involve multiple potential attack paths, including but not limited to memory corruption issues, improper access control, or protocol parsing failures. The impact extends beyond simple service disruption to potentially compromise the entire system availability, as the affected services are fundamental to system management and deployment operations.
From an operational perspective, this vulnerability presents a severe threat to enterprise environments that rely on NEC management platforms for critical infrastructure operations. The ability to remotely trigger system shutdown or restart commands can result in significant business disruption, data loss, and service interruptions. Organizations using these platforms face the risk of unauthorized personnel gaining the capability to disrupt critical operations without requiring elevated privileges or complex attack chains. The attack surface is particularly concerning given that the vulnerability affects multiple NEC management products, suggesting a widespread impact across different deployment scenarios. The fact that this vulnerability allows for OS-level actions rather than just application-level disruptions means that the consequences extend far beyond simple service outages to potentially compromise entire server environments. Security teams must consider the cascading effects of such attacks, as system restarts can interrupt backup operations, cause data corruption, and result in extended downtime for critical business applications.
Organizations should implement immediate mitigations including network segmentation to restrict access to port 56010, deployment of firewall rules to limit access to trusted IP addresses, and implementation of intrusion detection systems to monitor for anomalous packet patterns on the affected port. The vulnerability aligns with CWE-121, which addresses stack-based buffer overflow conditions, and potentially CWE-122, which covers heap-based buffer overflow issues, both of which are common in service-oriented applications handling network input. From an ATT&CK framework perspective, this vulnerability maps to T1499.004, which covers network denial of service attacks, and potentially T1566.001 for initial access through network services. System administrators should also consider implementing network monitoring solutions to detect unusual traffic patterns on port 56010 and establish incident response procedures for handling potential exploitation attempts. The most effective long-term solution involves upgrading to patched versions of NEC WebSAM DeploymentManager and the associated management platforms, as the vulnerability cannot be effectively mitigated through network configuration alone due to its fundamental nature within the service implementation.
