The CVE-2023-2140 vulnerability represents a critical server-side request forgery flaw affecting DELMIA Apriso versions from 2017 through 2022, classified under CWE-918 as insecure server-side request forwarding. This vulnerability allows unauthenticated attackers to exploit the application's ability to make HTTP requests to arbitrary destinations, effectively enabling them to perform unauthorized network operations on behalf of the targeted server. The flaw exists within the application's request handling mechanisms where user-supplied input is not properly validated or sanitized before being used to construct outbound requests to external systems. This creates a pathway for attackers to potentially access internal network resources, bypass firewalls, or perform reconnaissance activities against systems that would normally be protected from external access.
The technical exploitation of this vulnerability occurs when an attacker crafts malicious input that gets processed by the DELMIA Apriso application and subsequently used to initiate HTTP requests to targets of their choosing. The server processes these requests without adequate validation of destination addresses, allowing attackers to direct traffic to internal systems, external malicious servers, or other sensitive resources within the network perimeter. This vulnerability particularly impacts industrial manufacturing and enterprise resource planning environments where DELMIA Apriso is commonly deployed, as it can be leveraged to escalate privileges and gain unauthorized access to critical infrastructure components. The attack surface is further expanded when considering that many industrial environments lack robust network segmentation, making internal systems more accessible to compromised applications.
The operational impact of this vulnerability extends beyond simple data exfiltration or unauthorized access, as it can enable attackers to perform extensive reconnaissance and lateral movement within the network. Attackers can use this vulnerability to map internal network topology, identify vulnerable systems, and potentially establish persistence mechanisms by targeting internal services that are not directly exposed to external networks. This makes the vulnerability particularly dangerous in enterprise environments where industrial control systems and operational technology networks are interconnected with corporate IT infrastructure. The lack of authentication requirements for exploitation means that any attacker with network access to the vulnerable application can immediately begin leveraging this capability without requiring credentials or prior access to the system.
Organizations should implement immediate mitigations including network segmentation to isolate the affected DELMIA Apriso applications from critical internal systems, implementing strict outbound firewall rules to prevent connections to unauthorized destinations, and applying the vendor-provided patches or updates as soon as they become available. The vulnerability aligns with ATT&CK technique T1071.004 for application layer protocol: DNS and T1018 for remote system discovery, as attackers can use this capability to perform network reconnaissance and lateral movement. Additional defensive measures should include input validation and sanitization of all user-supplied data, implementing web application firewalls to monitor and block suspicious request patterns, and conducting regular security assessments to identify similar vulnerabilities in other enterprise applications. The vulnerability demonstrates the importance of secure coding practices and input validation in industrial control systems where the consequences of exploitation can extend beyond traditional cybersecurity impacts to potentially affect operational technology and physical safety systems.
