Overview<\/strong><\/p>\n

A critical vulnerability, designated as CVE-2025-23327, has been identified in NVIDIA’s Triton Inference Server for Windows and Linux. This vulnerability can lead to an integer overflow if exploited, potentially causing denial of service and data tampering. This issue is particularly concerning as it can affect critical systems and lead to potential system compromise or data leakage if not addressed promptly.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-23327
\nSeverity: High (CVSS: 7.5)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Denial of service and data tampering leading to potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

NVIDIA Triton Inference Server for Windows | All pre-patch versions
\nNVIDIA Triton Inference Server for Linux | All pre-patch versions<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit leverages the lack of proper input validation in the NVIDIA Triton Inference Server. An attacker can craft specific inputs that cause an integer overflow within the server’s processing component. This overflow can lead to unpredictable server behavior, which may include crashes (leading to a denial of service) and potential data tampering.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

A conceptual example of an exploit might be a specially crafted JSON payload like the following:<\/p>\n

POST \/infer HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n\"inputs\": [\n{\n\"name\": \"input0\",\n\"datatype\": \"INT32\",\n\"shape\": [0, -2147483648]\n}\n]\n}<\/code><\/pre>\n
In this example, the `shape` array contains an extremely large negative integer, which may cause an integer overflow if the server does not properly validate and handle the input.<\/p>\n
Mitigation<\/strong><\/p>\n
Users are advised to apply the vendor-supplied patch as soon as possible. If a patch cannot be applied immediately, implementing Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can provide temporary mitigation.<\/p>\n","protected":false},"excerpt":{"rendered":"
