CVE-2023-46306
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 · uneditedThe web administration interface in NetModule Router Software (NRSW) 4.6 before 4.6.0.106 and 4.8 before 4.8.0.101 executes an OS command constructed with unsanitized user input: shell metacharacters in the /admin/gnssAutoAlign.php device_id parameter. This occurs because another thread can be started before the trap that triggers the cleanup function. A successful exploit could allow an authenticated user to execute arbitrary commands with elevated privileges. NOTE: this is different from CVE-2023-0861 and CVE-2023-0862, which were fixed in version 4.6.0.105.
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 confidenceCommand injection vulnerability in NetModule Router Software's web admin interface (gnssAutoAlign.php) where the device_id parameter accepts unsanitized user input containing shell metacharacters. An authenticated attacker can execute arbitrary OS commands with elevated privileges due to unsanitized input being passed to an OS command combined with a race condition where another thread can start before the cleanup function trap triggers.

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 NetModule Router Software versionAccess the router's web admin interface and navigate to System > Status or check /etc/version file via SSH if available. The version is typically displayed on the dashboard or in 'System Information' section.Affected if The installed version is < 4.6.0.105 OR (>= 4.7.0.0 AND < 4.7.0.103)
-
Confirm web admin interface is accessibleAttempt to access the router's web interface via HTTPS/HTTP on the typical management ports (typically 443 or 8080). Check if gnssAutoAlign.php responds: try accessing /admin/gnssAutoAlign.php or the equivalent path on your device.Affected if The gnssAutoAlign.php script is present and reachable on the web interface
-
Verify administrative authentication statusCheck whether the device's administrative interface is exposed to untrusted networks. Review firewall rules or access control lists that govern who can reach the web admin port.Affected if The administrative interface is accessible from untrusted/direct internet-facing networks
-
Inspect for suspicious command executionIf you have CLI access, review system logs (typically in /var/log/ or via 'logread' command) for unusual commands or shell invocations around the time of the gnssAutoAlign.php endpoint being accessed. Look for unexpected process spawning.Affected if Logs show unexpected shell command execution or processes spawned from the web server user
-
Check for evidence of exploitationReview web server access logs for requests to gnssAutoAlign.php with unusual device_id parameter values containing shell metacharacters (such as ; | & $ ` or whitespace combined with commands).Affected if Access logs contain requests to gnssAutoAlign.php with shell metacharacters in the device_id parameter
You are affected if the device runs NetModule Router Software versions < 4.6.0.105 or between 4.7.0.0 and 4.7.0.102, AND the gnssAutoAlign.php web interface is accessible to an authenticated attacker.

dbcve · scoped4.6.0.1054.7.0.103
Update to version 4.6.0.106 (for 4.6.x) or 4.8.0.101 (for 4.8.x) or later. If immediate patching is not feasible, restrict administrative interface access to trusted networks and implement monitoring for suspicious command execution.
NetModule Router Software 4.6.0.106, 4.7.0.103, or 4.8.0.101 (depending on your major version branch)
- 1. Identify the currently installed NetModule Router Software version through the web administration interface or CLI
- 2. If running version 4.6.x and below 4.6.0.106, plan upgrade to version 4.6.0.106 or later
- 3. If running version 4.7.x and below 4.7.0.103, plan upgrade to version 4.7.0.103 or later
- 4. If running version 4.8.x and below 4.8.0.101, plan upgrade to version 4.8.0.101 or later
- 5. Before upgrading, backup the current router configuration
- 6. Download the appropriate firmware from NetModule's official support portal (share.netmodule.com)
- 7. Upload the firmware through the web administration interface under System > Software Update or via CLI
- 8. Verify the upgrade was successful and the new version is running
