1. Overview

• Product Affected: NVIDIA NeMo Curator (AI model/data management tool on Windows, Linux, macOS)

• Vulnerability: Code injection via malicious file processing

• CVSS v3.1 Score: 7.8 (High) — Low Attack Complexity, Low Privilege Required, No User Interaction, High C/I/A impact CVE Vulnerabilities Database+9NVIDIA Support+9CVETodo+9

• CWE: CWE‑94 – Improper Control of Generation of Code (Code Injection) CVE Details+3NVD+3OffSeq Threat Radar+3

2. Technical Details

• Attack Vector: Local — attacker supplies a malformed file that NeMo Curator processes to trigger code execution on host CVEFeed+9CVE Details+9CVETodo+9.

• Impacts:

  • Arbitrary code execution

  • Privilege escalation

  • Sensitive data disclosure & tampering OffSeq Threat Radar+1CVE Details+6NVD+6OffSeq Threat Radar+6

3. MITRE ATT&CK Mapping

4. Attacker’s Perspective

• Initial Access: Insider or attacker drops a crafted file in the processing queue

• Execution: Host-level code executes under NeMo Curator context

• Post-Compromise: Can pivot, tamper models/data, escalate privileges — especially critical in AI pipelines

5. Detection & Hunting Guidance

• Monitor suspicious file-handling and parser errors in NeMo Curator logs

• Alert on unexpected child process spawns (e.g., shell access from curator context)

• Leverage EDR to catch anomalous local file executions or injections

6. Mitigation & Remediation Strategy

• Patch immediately: Upgrade to NeMo Curator v25.07 or above X (formerly Twitter)+3incibe.es+3CVETodo+3CVE Details+1X (formerly Twitter)+3CVETodo+3OffSeq Threat Radar+3incibe.es+4CVEFeed+4OffSeq Threat Radar+4cve.org+12NVIDIA Support+12OffSeq Threat Radar+12OffSeq Threat Radar+1

• Tighten access controls: Restrict file creation/upload capabilities and segregate AI dev systems

• Sandbox file processing pipelines and perform rigorous input validation

• Enable runtime protections: ASLR, DEP, and EDR controls to detect post-exploitation behavior

7. Strategic Takeaways

• AI infrastructure security matters — vulnerabilities in AI tools like NeMo can lead to systemic compromises

• Prevention of malicious file ingestion is critical — input validation is a frontline defense

• Prioritize fast patch cycles and monitor trusted tools treated as critical infrastructure
