CVE-2024-0087: Nvidia Triton Inference Server RCE Flaw

CVE-2024-0087 Overview

NVIDIA Triton Inference Server for Linux contains a vulnerability where a user can set the logging location to an arbitrary file. If this file exists, logs are appended to the file. This External Control of File Name or Path vulnerability (CWE-73) allows authenticated attackers to manipulate the server's logging functionality to write to arbitrary files on the target system. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering.

Critical Impact

Authenticated attackers can leverage arbitrary file write capabilities to achieve remote code execution, escalate privileges, or cause denial of service on systems running NVIDIA Triton Inference Server.

Affected Products

• NVIDIA Triton Inference Server (all vulnerable versions)
• Linux Kernel (as underlying operating system)

Technical Details for CVE-2024-0087

Vulnerability Analysis

This vulnerability stems from improper validation of user-controlled input when configuring logging destinations in NVIDIA Triton Inference Server. The server fails to adequately restrict the file path that users can specify for log output, allowing authenticated users to direct log writes to arbitrary locations on the file system.

The attack can be initiated remotely over the network by authenticated users with low privileges and requires no user interaction. The impact is significant across all three security dimensions—confidentiality, integrity, and availability—as successful exploitation can lead to unauthorized data access, file tampering, and service disruption.

The vulnerability is classified under CWE-73 (External Control of File Name or Path), which occurs when software uses external input to construct a pathname for a file system operation without properly neutralizing special elements. In this case, the logging configuration mechanism accepts user-supplied file paths without sufficient validation.

Root Cause

The root cause is the lack of proper input validation and path canonicalization when processing user-specified logging file paths. The NVIDIA Triton Inference Server allows users to configure logging destinations through its API or configuration interface, but fails to implement adequate security controls to prevent path traversal or writing to sensitive system locations.

This external control of file names enables attackers to:

• Write to configuration files that may be parsed and executed
• Overwrite critical system files causing denial of service
• Append malicious content to script files for code execution
• Access or corrupt sensitive data files

Attack Vector

The attack is network-based and can be performed by any authenticated user with basic privileges on the Triton Inference Server. The attacker exploits the logging configuration functionality by specifying a malicious file path as the logging destination.

The exploitation flow typically involves:

1. The attacker authenticates to the NVIDIA Triton Inference Server with low-privileged credentials
2. The attacker configures the logging location to point to a sensitive file path (e.g., a cron job file, SSH authorized keys, or web server configuration)
3. The attacker triggers actions that generate log entries containing attacker-controlled content
4. The malicious log content is appended to the target file, potentially enabling code execution or privilege escalation

Since no verified code examples are available for this vulnerability, organizations should refer to the NVIDIA Security Advisory for detailed technical information on the vulnerability mechanics and exploitation scenarios.

Detection Methods for CVE-2024-0087

Indicators of Compromise

• Unexpected modifications to system configuration files, scripts, or sensitive files that could be targets for log injection
• Triton Inference Server log configuration changes pointing to non-standard or suspicious file paths
• Unusual file write operations originating from the Triton Inference Server process to locations outside normal logging directories
• Evidence of path traversal sequences (e.g., ../) in Triton server configuration or API requests

Detection Strategies

• Monitor Triton Inference Server configuration changes, particularly modifications to logging destination settings
• Implement file integrity monitoring (FIM) on critical system files and directories to detect unauthorized modifications
• Analyze Triton server access logs for API calls that modify logging configuration with suspicious file paths
• Deploy endpoint detection rules to alert on Triton server processes writing to sensitive system locations

Monitoring Recommendations

• Enable comprehensive audit logging for all Triton Inference Server configuration changes
• Configure alerts for any logging path changes that target directories outside designated log storage areas
• Implement SentinelOne's behavioral AI to detect anomalous file write patterns from the Triton server process
• Monitor for privilege escalation attempts or unusual process spawning following Triton server activity

How to Mitigate CVE-2024-0087

Immediate Actions Required

• Apply the latest security patches from NVIDIA for Triton Inference Server as referenced in the vendor advisory
• Review and restrict user permissions to the logging configuration functionality
• Implement allowlisting for permitted logging directory paths at the operating system level
• Audit current logging configurations to ensure they point only to intended, safe locations

Patch Information

NVIDIA has released security updates addressing this vulnerability. Detailed patch information and remediation guidance is available in the NVIDIA Security Advisory. Organizations should update to the latest patched version of NVIDIA Triton Inference Server as soon as possible.

Workarounds

• Restrict network access to the Triton Inference Server to trusted IP ranges only using firewall rules
• Implement strict file system permissions to prevent the Triton server process from writing outside designated log directories
• Use containerization or sandboxing to limit the server's file system access scope
• Disable or restrict API endpoints that allow logging configuration changes until patches can be applied

# Example: Restrict Triton server log directory permissions
# Create dedicated log directory with restricted permissions
mkdir -p /var/log/triton-inference-server
chown triton:triton /var/log/triton-inference-server
chmod 750 /var/log/triton-inference-server

# Use SELinux or AppArmor to confine Triton server file access
# Example AppArmor rule to restrict write locations
# /etc/apparmor.d/local/triton-server
# /var/log/triton-inference-server/** rw,
# deny /** w,
