CVE-2025-2172 Overview
CVE-2025-2172 is a command injection vulnerability in Aviatrix Controller, a cloud networking management platform. The flaw stems from improper sanitization of user input before it is passed to command line utilities. Attackers can inject arbitrary shell commands through special characters embedded in filenames. The vulnerability affects Aviatrix Controller releases prior to 7.1.4208, 7.2.5090, and 8.0.0. Successful exploitation grants remote code execution on the Controller host, exposing managed cloud networking infrastructure across AWS, Azure, and GCP environments. The issue is tracked under CWE-78 (OS Command Injection) and was disclosed by Mandiant as MNDT-2025-0004.
Critical Impact
Authenticated attackers can achieve remote code execution on the Aviatrix Controller, compromising cloud network orchestration and potentially pivoting into managed cloud accounts.
Affected Products
- Aviatrix Controller versions prior to 7.1.4208

Technical Details for CVE-2025-2172
Vulnerability Analysis
Aviatrix Controller accepts user-supplied filenames through management workflows and passes them to underlying operating system utilities without adequate sanitization. When a filename contains shell metacharacters such as backticks, semicolons, pipes, or command substitution syntax, the Controller executes the embedded commands in the context of the Controller process. This behavior corresponds to CWE-78, OS Command Injection. Because the Aviatrix Controller manages cloud networking policy, VPN configurations, and inter-VPC routing across public clouds, code execution on the appliance directly threatens the integrity of downstream cloud infrastructure. Mandiant researchers detailed the exploitation mechanics in the Google Cloud Threat Intelligence advisory.
Root Cause
The Controller invokes command line utilities using string concatenation of user-controlled filename values. No allowlist or shell-escaping routine sits between the input and the process invocation. Any character that a POSIX shell interprets as a control token becomes an execution primitive.
Attack Vector
Exploitation requires network access to the Controller and high-privilege credentials, according to the CVSS 4.0 vector. An authenticated attacker submits a crafted filename containing shell metacharacters through a Controller function that later passes the value to a command line utility. The Controller shell interprets the injected characters and runs attacker-supplied commands with the privileges of the Controller service.
See the Mandiant Vulnerability Disclosure MNDT-2025-0004 for the reported attack path.
Detection Methods for CVE-2025-2172
Indicators of Compromise
- Unexpected child processes spawned by the Aviatrix Controller service (for example, sh, bash, curl, wget, nc).
- Filenames in Controller logs containing shell metacharacters such as `, ;, |, $(, or &&.
- New cron jobs, systemd units, or SSH keys created on the Controller host outside normal change windows.
- Outbound network connections from the Controller to unknown external hosts.
Detection Strategies
- Alert on Aviatrix Controller process trees that deviate from the baseline set of expected child processes.
- Inspect Controller application logs for filename fields containing non-alphanumeric characters not present in legitimate filenames.
- Correlate authentication events for high-privilege Controller accounts with subsequent file upload or configuration change activity.
Monitoring Recommendations
- Forward Aviatrix Controller system, application, and audit logs to a centralized SIEM for retention and correlation.
- Monitor cloud provider audit trails (AWS CloudTrail, Azure Activity Log, GCP Audit Logs) for changes initiated by Controller-linked service principals.
- Enable process execution telemetry on the Controller host to capture command line arguments for post-incident analysis.
How to Mitigate CVE-2025-2172
Immediate Actions Required
- Upgrade Aviatrix Controller to 7.1.4208, 7.2.5090, 8.0.0, or later as appropriate for your release train.
- Rotate all Controller administrative credentials and API keys following the upgrade.
- Review Controller audit logs for evidence of filename-based command injection prior to patching.
- Restrict management-plane network access to the Controller to trusted administrative networks only.
Patch Information
Aviatrix has released fixed builds 7.1.4208, 7.2.5090, and 8.0.0. Apply the patch that aligns with your current major release. Vendor guidance is available through the Mandiant disclosure and the Google Cloud Threat Intelligence writeup.
Workarounds
- Limit access to Controller functions that accept filename input to a minimal set of trusted administrators.
- Place the Controller behind a management VPN or bastion host and block direct internet exposure.
- Enforce multi-factor authentication on all Controller accounts to raise the bar for the authenticated access required to exploit this flaw.
- Monitor for and block outbound connections from the Controller to unapproved destinations until patching is complete.
