CVE-2019-18325 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-2019-18326, 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-2019-18325 affects the SPPA-T3000 MS3000 Migration Server, a critical component in industrial automation and control systems. This device serves as a migration server facilitating the transition of industrial processes from older to newer systems, making it a potential target for sophisticated attacks targeting operational technology infrastructure. The vulnerability resides within the server's handling of network communications on port 5010, which is specifically designated for migration protocol operations. The affected system operates in environments where industrial control systems require reliable and secure communication channels, making this vulnerability particularly concerning for critical infrastructure protection.
The technical flaw manifests as a buffer overflow or improper input validation vulnerability in the server's protocol handler for the designated port. When an attacker sends specifically crafted packets to the TCP port 5010, the system fails to properly validate the incoming data structure, leading to memory corruption that can result in system instability. This vulnerability operates at the network protocol level, where the server's response to malformed packets causes unexpected behavior that can manifest as denial-of-service conditions or potentially enable remote code execution. The flaw demonstrates characteristics consistent with CWE-121, heap-based buffer overflow, or CWE-122, stack-based buffer overflow, depending on the specific implementation details of the vulnerable code.
The operational impact of this vulnerability extends beyond simple service disruption, as it represents a significant risk to industrial control system integrity. A successful exploitation could allow an attacker to gain remote code execution privileges on the migration server, potentially enabling them to manipulate industrial processes or access sensitive operational data. The vulnerability's independence from other related CVEs suggests it operates through a distinct code path or protocol implementation, making it particularly dangerous as it could be exploited in combination with other vulnerabilities. Organizations relying on SPPA-T3000 systems face potential risks to their industrial automation processes, especially in environments where network segmentation is not properly implemented, allowing direct network access to the affected server.
Network access to the MS3000 server is required for exploitation, which provides some inherent protection but also highlights the importance of network security controls in industrial environments. The vulnerability's exposure through TCP port 5010 indicates that it operates within the application layer protocol handling, making it susceptible to attacks that leverage protocol-specific weaknesses. Security professionals should consider this vulnerability in the context of the MITRE ATT&CK framework, particularly under the techniques related to remote service exploitation and privilege escalation. Organizations should implement network segmentation to isolate critical industrial systems, employ network monitoring to detect anomalous packet patterns, and maintain up-to-date vulnerability management processes to address such threats. The lack of known public exploitation at the time of advisory publication does not diminish the severity of the vulnerability, as it represents an unaddressed risk that could be weaponized by threat actors targeting industrial control systems.
