CVE-2019-18329 in SPPA-T3000 MS3000 Migration Server
Summary
by MITRE
A vulnerability has been identified in SPPA-T3000 MS3000 Migration Server (All versions). An attacker with network access to the MS3000 Server can cause a Denial-of-Service condition and potentially gain remote code execution by sending specifically crafted packets to 5010/tcp. This vulnerability is independent from CVE-2019-18323, CVE-2019-18324, CVE-2019-18325, CVE-2019-18326, CVE-2019-18327, CVE-2019-18328, and CVE-2019-18330. Please note that an attacker needs to have network access to the MS3000 in order to exploit this vulnerability. At the time of advisory publication no public exploitation of this security vulnerability was known.

The vulnerability identified as CVE-2019-18329 affects the SPPA-T3000 MS3000 Migration Server, a critical component in industrial automation systems used for managing and migrating data across distributed control systems. This particular vulnerability resides within the server's network service listening on TCP port 5010, representing a significant security risk for industrial control systems that rely on this migration infrastructure. The affected system operates within the context of industrial environments where network segmentation and security controls may be less stringent than in traditional enterprise networks, making it particularly concerning for operational technology environments.
The technical flaw manifests through a buffer overflow condition that occurs when the MS3000 Migration Server processes specifically crafted network packets sent to port 5010. This type of vulnerability falls under CWE-121, which describes stack-based buffer overflow conditions, and represents a classic remote code execution vector that can be exploited by attackers with network access to the target system. The vulnerability is particularly dangerous because it allows for both denial-of-service conditions and potential remote code execution, providing attackers with a pathway to compromise the entire migration server infrastructure. The attack requires only network access to the target system, eliminating the need for physical access or complex social engineering tactics.
From an operational impact perspective, this vulnerability poses a severe threat to industrial control system environments where the MS3000 Migration Server serves as a critical component in data migration and system management processes. The potential for denial-of-service conditions can disrupt critical industrial operations, while the remote code execution capability allows attackers to establish persistent access to the industrial network infrastructure. This vulnerability aligns with ATT&CK technique T1190, which describes exploiting vulnerabilities in remote services, and represents a significant risk for organizations following the NIST Cybersecurity Framework, particularly in the Protect and Detect functions. The vulnerability's independence from other related CVEs in the same advisory series indicates that multiple attack vectors exist within the same product line, suggesting a systemic security weakness in the overall architecture.
The exploitation of this vulnerability requires an attacker to have network access to the target MS3000 server, which typically means either direct network connectivity or access through network bridges that provide access to the industrial control network. This requirement aligns with ATT&CK technique T1133, which describes external remote services that can be accessed from external networks. Organizations should implement network segmentation controls and restrict access to port 5010 to only authorized network segments and personnel. The lack of public exploitation reports at the time of advisory publication does not diminish the severity of this vulnerability, as industrial systems often remain unpatched for extended periods, creating a window of opportunity for adversaries to develop and deploy exploits. Mitigation strategies should include immediate patch deployment, network access controls, and monitoring for anomalous traffic patterns on port 5010. The vulnerability demonstrates the importance of securing industrial control system components and highlights the need for comprehensive vulnerability management programs that address both traditional enterprise systems and specialized industrial infrastructure.
