How the Exploit Works

The identified vulnerability arises from a double-free condition in the NVIDIA Triton Inference Server. This situation occurs when the software attempts to free the same memory location twice, leading to a potential memory corruption. An attacker who sends multiple cancellation requests before a stream is processed could trigger this vulnerability, causing a denial of service and potentially gaining the ability to execute arbitrary code.

Conceptual Example Code

Below is a conceptual representation of how a malicious actor might attempt to exploit this vulnerability:

POST /stream/cancel HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"stream_id": "target_stream_id",
"cancel_request": "true"
}
POST /stream/cancel HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"stream_id": "target_stream_id",
"cancel_request": "true"
}

In this example, the attacker sends multiple HTTP POST requests to the stream cancellation endpoint, targeting the same stream before it’s processed.

Vulnerability Summary

CVE ID: CVE-2025-46390
Severity: High (CVSS: 7.5)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

WebServerX | 1.0-2.5
WebAppY | 3.0-4.2

How the Exploit Works

An attacker exploiting the CVE-2025-46390 vulnerability would observe the behavior and responses of the targeted system under various conditions. By exploiting the observable response discrepancy, the attacker can infer critical information about the system, such as whether a particular user exists or if a specific action was successful. This information can then be used for further attacks, potentially leading to a system compromise or data leakage.

Conceptual Example Code

A conceptual example of exploiting this vulnerability might involve sending crafted HTTP requests and observing the responses. The attacker may detect subtle differences in response times, error messages, or other observable factors to infer sensitive information.

POST /login HTTP/1.1
Host: vulnerable.example.com
Content-Type: application/json
{ "username": "admin", "password": "guess" }

In this example, if the server responds quicker when the username exists, an attacker could systematically guess usernames until a response takes longer, indicating a valid username. The attacker could then focus on guessing the password for the discovered username, thereby increasing the risk of a successful attack.

Vulnerability Summary

CVE ID: CVE-2025-27073
Severity: High (7.5 CVSS score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

Network Operating System | All versions before 3.0

How the Exploit Works

The exploit works by sending a specially crafted NDP packet to a target device. During the processing of this packet, the system attempts to create a new NDP instance. However, due to the malformed nature of the packet, this causes an unexpected condition within the system leading to a transient DoS. The attacker can then exploit this instability to compromise the system or leak sensitive data.

Conceptual Example Code

Here’s a conceptual example of an NDP packet that might exploit the vulnerability:

echo "60 00 00 00 00 40 3A FF FE 80 00 00 00 00 00 00 02 02 B3 FF FE E4 00 00 FF 02 00 00 00 00 00 00 00 00 00 01 FF E4 00 00 87 00 6E 7E 00 00 00 00 01 01 02 02 B3 FF FE E4 00 00" | xxd -r -p | nc -u -w1 [target IP] 546

The above command sends a specially crafted NDP packet to the target IP on port 546, which is the standard port for the DHCPv6 client.
Please note that this is a conceptual demonstration of how the vulnerability might be exploited and should not be used maliciously.

Mitigation Guidance

To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it is available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by monitoring and blocking suspicious network traffic.
