CVE-2025-32815 Overview
CVE-2025-32815 is an authentication bypass vulnerability affecting Infoblox NETMRI network management appliances before version 7.6.1. The flaw stems from a hardcoded credential embedded in the product, which allows a remote attacker to bypass authentication controls over the network. Once authenticated, an attacker gains access to sensitive NETMRI functionality used to manage network infrastructure. The vulnerability is classified under [CWE-287] Improper Authentication and was published to the National Vulnerability Database (NVD) on May 22, 2025.
Critical Impact
Authentication bypass via a hardcoded credential grants remote attackers unauthorized access to Infoblox NETMRI, exposing network configuration data and administrative functions.
Affected Products
- Infoblox NETMRI versions prior to 7.6.1
- Deployments using the vulnerable NETMRI appliance for network change and configuration management
- All CPE-listed variants matching cpe:2.3:a:infoblox:netmri:*:*:*:*:*:*:*:*

Technical Details for CVE-2025-32815
Vulnerability Analysis
The vulnerability resides in the authentication logic of Infoblox NETMRI, a network automation and configuration management platform. NETMRI ships with a hardcoded credential that is accessible over the network. An attacker who obtains or derives this credential can authenticate to the appliance without possessing valid user credentials. The advisory from Infoblox confirms that versions before 7.6.1 are affected. Successful exploitation leads to unauthorized read access and limited write capability on the appliance. Because NETMRI holds credentials and configuration data for downstream network devices, compromise of the appliance can expand attacker reach into managed infrastructure. The Infoblox Security Advisory confirms the impact and remediation path. The EPSS probability places this CVE in the upper percentile of vulnerabilities likely to be exploited, indicating elevated attention from opportunistic scanners.
Root Cause
The root cause is the presence of a hardcoded credential shipped in the NETMRI product. Static credentials embedded in software violate secure design principles because they cannot be rotated by administrators and are shared across all deployments. Once such a credential is discovered, every unpatched instance is exposed.
Attack Vector
The attack vector is network-based and requires no user interaction. An attacker with network reachability to the NETMRI management interface submits the hardcoded credential to the authentication endpoint. The high attack complexity reflects that the attacker must know or discover the hardcoded value. The vulnerability mechanism is described in prose only; no verified public exploit code is available at the time of writing.
Detection Methods for CVE-2025-32815
Indicators of Compromise
- Successful authentication events on NETMRI from unexpected source IP addresses, especially from outside administrative networks
- Login sessions from accounts that do not correspond to provisioned NETMRI operators
- Configuration exports, credential retrievals, or device inventory queries occurring outside change windows
Detection Strategies
- Review NETMRI authentication logs for logins that do not map to known administrator accounts
- Correlate NETMRI access events with downstream network device configuration changes to detect lateral impact
- Monitor for API calls to sensitive NETMRI endpoints originating from non-management subnets
Monitoring Recommendations
- Forward NETMRI audit and authentication logs to a centralized SIEM for retention and correlation
- Alert on any authentication success from source IPs outside the documented management network
- Track anomalous session durations and off-hours activity against the appliance
How to Mitigate CVE-2025-32815
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 using firewall rules and management VLAN segmentation
- Rotate credentials for any downstream network devices whose secrets are stored in NETMRI if compromise is suspected
- Review authentication and audit logs since deployment for signs of unauthorized access
Patch Information
Infoblox has released a fixed version. Administrators should apply NETMRI 7.6.1 or later. Refer to the Infoblox Security Advisory for upgrade instructions and version-specific guidance.
Workarounds
- Place NETMRI behind a jump host or bastion that enforces multi-factor authentication before allowing access to the management interface
- Apply strict access control lists so that only designated administrator workstations can reach NETMRI over the network
- Increase logging verbosity and shorten log forwarding intervals until the patch is applied
# Example: restrict access to NETMRI management interface with iptables
iptables -A INPUT -p tcp -s 10.10.20.0/24 --dport 443 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
