Summary

CVE-2025-23317 is a critical-severity Heap-based Buffer Overflow (CWE-122) vulnerability in Nvidia Triton Inference Server. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 22% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

NVIDIA Triton Inference Server is affected by a vulnerability in its HTTP server component, tracked as CVE-2025-23317 and assigned CWE-122. The flaw permits an attacker to initiate a reverse shell through a specially crafted HTTP request, which can result in remote code execution, denial of service, data tampering, or information disclosure. The issue carries a CVSS v3.1 score of 9.1, reflecting network attack vector, low complexity, and no required privileges or user interaction.

Unauthenticated remote attackers can exploit the vulnerability over the network by submitting the malicious request to the HTTP server interface. Successful exploitation grants the ability to execute arbitrary code, disrupt service availability, modify data, or access sensitive information on the affected inference server instance.

The EPSS score has remained low, moving only from 0.0488 currently to a peak of 0.0572 with no indication of significant exploitation interest after disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (including fuzzing and memory-error detectors) can discover heap overflows after they have been coded.

Input validation enforces bounds checking on data written to heap buffers, directly stopping the overflow condition from being introduced.

Security engineering principles require use of memory-safe constructs and bounds-checked allocation routines that avoid introducing heap overflows.

Memory-protection mechanisms limit the ability of a heap overflow to execute attacker-controlled code or corrupt adjacent structures.
