CVE-2025-7328
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMultiple Broken Authentication security issues exist in the affected product. The security issues are due to missing authentication checks on critical functions. These could result in potential denial-of-service, admin account takeover, or NAT rule modifications. Devices would no longer be able to communicate through NATR as a result of denial-of-service or NAT rule modifications. NAT rule modification could also result in device communication to incorrect endpoints. Admin account takeover could allow modification of configuration and require physical access to restore.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceMissing authentication checks on critical functions in the affected product allow unauthenticated attackers to perform admin account takeover, modify NAT rules, or cause denial-of-service. Successful exploitation can disrupt NATR communication and enable traffic redirection to incorrect endpoints.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm device modelIdentify if the network device is a Rockwell Automation 1783 NATR model by checking the device hardware label, SNMP sysDescr, or web management interface headerAffected if Device is not a 1783 NATR unit - this CVE does not apply
-
Determine installed firmware versionAccess the device web interface, CLI (show version), or SNMP OID to retrieve the current firmware version. Compare against the vulnerable range: any version below 1.007Affected if Firmware version is 1.006 or lower, or version cannot be determined and device is a 1783 NATR
-
Verify management interface exposureCheck network configuration to determine if the device management interface (web UI, CLI, or SNMP) is accessible from untrusted networks or the internetAffected if Management interface is exposed to untrusted networks and firmware version is below 1.007
-
Inspect NAT rule configurationReview the NAT rule configuration through the device web interface or CLI (show nat rules) for any unauthorized or unexpected NAT mappingsAffected if Unexpected or unauthorized NAT rules exist and firmware version is below 1.007
-
Review administrator accountsCheck the local administrator account list through the device management interface for any unknown, added, or modified admin accountsAffected if Unknown administrator accounts are present or existing accounts have been modified without authorization
If the device is a Rockwell Automation 1783 NATR with firmware version below 1.007 and its management interface is network-accessible, the environment is affected by this authentication bypass vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.007
Implement proper authentication and authorization checks on all critical functions, particularly those affecting admin accounts and NAT rule management. Consider firmware updates if available from vendor.
1783 Natr Firmware version 1.007 or later
- Obtain the 1783 Natr firmware version 1.007 or later from the Rockwell Automation website or support portal
- Follow the manufacturer's official firmware upgrade procedure for the 1783 Natr device
- After upgrading, verify the firmware version is 1.007 or higher by checking the device management interface
- Test that critical functions including NAT rules, admin access, and device communication are working properly after the upgrade
- Verify that the missing authentication vulnerabilities are no longer present by confirming critical functions now require proper authentication
