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-2019-18325, CVE-2019-18326, CVE-2019-18327, CVE-2019-18328, CVE-2019-18329, 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-2019-18324 affects the SPPA-T3000 MS3000 Migration Server, a critical component in industrial automation and control systems that facilitates migration processes for legacy systems. This particular vulnerability resides within the server's network communication handling mechanism, specifically targeting the service listening on TCP port 5010. The affected system represents a significant operational technology infrastructure element that requires robust security measures due to its role in managing industrial processes and data migration. The vulnerability's presence in the migration server component is particularly concerning as it could disrupt critical industrial operations during system transitions, potentially leading to production downtime and operational failures that impact entire industrial facilities.
The technical flaw manifests as a failure in input validation and buffer handling within the MS3000 server's network protocol implementation. When maliciously crafted packets are sent to the designated port 5010, the server processes these packets without adequate sanitization, leading to unpredictable behavior that can result in denial-of-service conditions. The vulnerability's exploitation mechanism suggests a lack of proper boundary checking or memory management in the server's packet processing routine, which could potentially allow for arbitrary code execution under specific conditions. This type of vulnerability aligns with CWE-121, which describes stack-based buffer overflow conditions, or CWE-787, representing out-of-bounds write vulnerabilities that could be exploited through improper input handling. The attack surface is limited to network-accessible systems, requiring attackers to establish connectivity to the target server's designated port, which provides some network-based protection but does not eliminate the threat entirely.
The operational impact of this vulnerability extends beyond simple service disruption to potentially compromise the integrity of industrial control systems that rely on the MS3000 Migration Server for their operations. Denial-of-service conditions could halt critical migration processes, leading to operational delays, data inconsistencies, and potential safety risks in industrial environments where timing and reliability are paramount. The possibility of remote code execution adds another layer of severity, as successful exploitation could allow attackers to gain full control over the server's operations, potentially enabling them to manipulate industrial processes, access sensitive operational data, or establish persistent access points within the industrial network infrastructure. This vulnerability particularly affects the ATT&CK technique T1105, which involves remote service execution, and could contribute to broader attack chains involving lateral movement and privilege escalation within industrial control networks.
Organizations should implement immediate network segmentation measures to isolate the MS3000 Migration Server from unauthorized network access, particularly ensuring that TCP port 5010 is not exposed to untrusted networks. Network access control lists should be configured to restrict access to the server from only authorized network segments, and regular network monitoring should be implemented to detect unusual traffic patterns on the affected port. The recommended mitigation strategy includes applying vendor-provided patches or updates as soon as they become available, while simultaneously implementing network-based intrusion detection systems to monitor for exploitation attempts. Additionally, organizations should conduct thorough network assessments to identify all instances of the affected software and ensure that proper network hygiene practices are maintained to prevent unauthorized access to industrial control system components. The vulnerability's classification as a remote code execution risk necessitates immediate attention and comprehensive security hardening measures to protect critical industrial infrastructure from potential compromise.
