CVE-2025-6205: Unchecked Privilege Escalation in DELMIA Apriso

Overview

CVE-2025-6205 is a cybersecurity vulnerability that affects DELMIA Apriso, a popular application used for manufacturing operations management. This critical vulnerability, which lies in the application’s failure to properly authorize users, could potentially allow an attacker with malicious intent to gain unauthorized, privileged access to the system. This could lead to severe consequences including system compromise or data leakage, making it a high-risk issue that needs to be urgently addressed.

How the Exploit Works

The exploit takes advantage of a missing authorization vulnerability in DELMIA Apriso. The application fails to correctly implement access controls, allowing an attacker to bypass the normal authorization process. This could potentially allow a malicious actor to gain elevated privileges on the application, giving them the ability to manipulate data and potentially compromise the entire system.

Conceptual Example Code

The following is a hypothetical example of how the vulnerability might be exploited. This pseudocode is meant to illustrate the concept and does not represent actual exploit code:

POST /delemia_endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"auth": {
"username": "attacker",
"password": "guess"
},
"action": {
"elevate_privileges": {
"user": "attacker",
"role": "admin"
}
}
}

In this example, the attacker sends a POST request to a vulnerable endpoint on the target system. The attacker uses their own low-level credentials but includes an action to elevate their privileges to an admin role. Due to the missing authorization vulnerability, the application fails to check the validity of this action, and the attacker gains elevated privileges.

Mitigation

To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could serve as temporary mitigation by detecting and blocking attempts to exploit this vulnerability.
