CVE-2025-41673
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 · uneditedA high privileged remote attacker can execute arbitrary system commands via POST requests in the send_sms action due to improper neutralization of special elements used in an OS command.
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 · high confidenceThis is an OS command injection vulnerability in the send_sms action where a high-privileged remote attacker can execute arbitrary system commands through POST requests due to improper neutralization of special elements used in an OS command. The vulnerability allows remote code execution but requires high-privileged (authenticated) access to exploit.

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.
-
Identify Mbnet.mini firmware versionAccess the device web interface or check system information page for firmware version. Alternatively, use SNMP or CLI command 'show version' if available.Affected if The firmware version is less than 2.3.3 (e.g., 2.3.2, 2.3.1, 2.3.0, or earlier)
-
Confirm send_sms action is accessibleCheck if the web application's send_sms endpoint exists and is reachable. This is typically found in the SMS/messaging configuration section of the Mbnet.mini interface.Affected if The send_sms action is exposed and functional on the device
-
Verify authentication requirements for send_smsAttempt to access the send_sms functionality or inspect the web application's authentication configuration for this endpoint.Affected if The send_sms endpoint is accessible to high-privileged authenticated users (as opposed to requiring no authentication or being restricted to administrative accounts only)
-
Inspect web server configuration for command injection vectorsIf you have access to the device's configuration files or can view HTTP request handling, examine how the send_ssm parameter is processed before being passed to system command execution.Affected if User-supplied parameters in send_sms requests are passed directly to OS command functions without sanitization
The device is affected if it is running Mbnet.mini firmware version prior to 2.3.3 and the send_sms functionality is accessible to high-privileged authenticated users.
Generated from the published advisory. Verify against your own configuration.
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 · scoped2.3.3
Implement strict input validation and sanitization on all user-supplied parameters in the send_sms action, and refactor code to avoid passing unsanitized input to OS command execution functions; use parameterized APIs or whitelisted inputs instead.
Firmware 2.3.3
- 1. Obtain the Mbnet.mini firmware version 2.3.3 or later from the official vendor (Mbnet) or verified distributor
- 2. Backup the current device configuration following vendor documentation
- 3. Access the Mbnet.mini device administrative interface
- 4. Navigate to the firmware update or system maintenance section
- 5. Upload and apply firmware version 2.3.3 or later
- 6. Verify the firmware update was successful by checking the firmware version in the device admin panel
- 7. Confirm the send_sms functionality operates normally post-update
- 8. Review device logs to ensure no anomalies
