CVE-2025-32813: Infoblox NetMRI RCE Vulnerability

CVE-2025-32813 Overview

CVE-2025-32813 is a remote command injection vulnerability affecting Infoblox NETMRI versions prior to 7.6.1. The flaw allows attackers to inject and execute arbitrary operating system commands against the NETMRI appliance over the network. NETMRI is a network automation and configuration management product deployed in enterprise environments to monitor and manage network device configurations.

The vulnerability is tracked under CWE-77: Improper Neutralization of Special Elements used in a Command. Successful exploitation grants attackers the ability to run commands in the context of the NETMRI service, potentially compromising managed network infrastructure.

Critical Impact

Command injection in NETMRI grants code execution on an appliance that holds privileged credentials to manage routers, switches, and firewalls across the enterprise network.

Affected Products

• Infoblox NETMRI versions prior to 7.6.1
• Deployments exposing the NETMRI web interface to untrusted networks
• Environments using NETMRI for automated network configuration management

Technical Details for CVE-2025-32813

Vulnerability Analysis

The vulnerability resides in Infoblox NETMRI, a network management platform that automates device configuration, change tracking, and compliance auditing. The flaw permits command injection [CWE-77], where attacker-controlled input is incorporated into a system command without proper neutralization of shell metacharacters.

The EPSS score of 11.178% places this issue in the 93rd percentile of vulnerabilities by predicted exploitation likelihood. The advisory description indicates the issue can be reached remotely. While the original NVD description states the injection is unauthenticated, the CVSS vector lists PR:H, indicating Infoblox scored exploitation as requiring high privileges. Operators should treat both interpretations as exploitable and patch immediately.

Successful exploitation leads to arbitrary command execution on the NETMRI host with high impact across confidentiality, integrity, and availability.

Root Cause

The root cause is improper neutralization of shell metacharacters in input passed to an underlying command interpreter. When the application constructs a command string using attacker-supplied parameters, characters such as ;, |, &, and backticks are interpreted by the shell rather than treated as literal data. Infoblox has not published low-level technical details of the affected code path.

Attack Vector

The attack vector is network-based. An attacker sends a crafted HTTP request to a vulnerable endpoint of the NETMRI web management interface. The injected payload appends shell commands that execute on the appliance operating system. Because NETMRI typically stores administrative credentials for managed network devices, post-exploitation activity can pivot to switches, routers, and firewalls across the environment.

No code examples are provided. Refer to the Infoblox Security Advisory for CVE-2025-32813 for vendor guidance.

Detection Methods for CVE-2025-32813

Indicators of Compromise

• Unexpected child processes spawned by the NETMRI web service, such as sh, bash, nc, curl, or wget
• Outbound network connections from the NETMRI appliance to unknown external hosts
• New or modified files in NETMRI web-accessible directories or temporary paths
• Anomalous HTTP requests containing shell metacharacters (;, |, &&, `, $() in parameter values

Detection Strategies

• Inspect NETMRI web server access logs for requests containing encoded or raw shell metacharacters in query strings and POST bodies
• Monitor process execution telemetry on the NETMRI host for shell processes parented by the web application
• Correlate authentication logs on managed network devices with NETMRI activity to detect unauthorized configuration changes

Monitoring Recommendations

• Forward NETMRI appliance logs and host telemetry to a centralized SIEM for retention and correlation
• Baseline normal outbound connections from the NETMRI appliance and alert on deviations
• Audit privileged credential usage from NETMRI to identify configuration changes outside scheduled automation windows

How to Mitigate CVE-2025-32813

Immediate Actions Required

• Upgrade Infoblox NETMRI to version 7.6.1 or later as directed by the vendor advisory
• Restrict network access to the NETMRI management interface to trusted administrative subnets only
• Rotate credentials stored in NETMRI for managed network devices if compromise is suspected
• Review NETMRI audit logs and managed device configurations for unauthorized changes

Patch Information

Infoblox has released NETMRI version 7.6.1 to address CVE-2025-32813. Customers should consult the Infoblox Security Advisory for CVE-2025-32813 for upgrade instructions and version-specific guidance. Apply the patch through standard Infoblox update procedures.

Workarounds

• Place the NETMRI management interface behind a VPN or jump host to remove direct network exposure
• Apply firewall access control lists permitting only authorized administrator source IPs to reach NETMRI
• Enable enhanced logging on the appliance and forward logs off-box to preserve evidence in case of compromise

# Example: restrict NETMRI web interface access with iptables
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
