CVE-2023-22279
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 · uneditedMAHO-PBX NetDevancer Lite/Uni/Pro/Cloud prior to Ver.1.11.00, MAHO-PBX NetDevancer VSG Lite/Uni prior to Ver.1.11.00, and MAHO-PBX NetDevancer MobileGate Home/Office prior to Ver.1.11.00 allow a remote unauthenticated attacker to execute an arbitrary 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 a command injection vulnerability in MAHO-PBX NetDevancer products (Lite/Uni/Pro/Cloud, VSG Lite/Uni, and MobileGate Home/Office) allowing remote unauthenticated attackers to execute arbitrary OS commands. The flaw exists prior to version 1.11.00 and is exploitable over the network without any authentication credentials.

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 MAHO-PBX NetDevancer devices on your networkInventory your network for devices branded as Ate Mahoroba Maho PBX NetDevancer, including Lite, Uni, Pro, Cloud, VSG Lite, VSG Uni, MobileGate Home, or MobileGate Office models. Check device labels, management interfaces, or network scans for these product names.Affected if Any NetDevancer device (Lite/Uni/Pro/Cloud, VSG Lite/Uni, or MobileGate Home/Office) is present in the environment
-
Check the installed firmware versionAccess the device management interface or use the vendor-provided method to retrieve the current firmware version. Compare it against the affected version range.Affected if The firmware version is lower than 1.11.00 (for example, 1.10.x, 1.9.x, etc.)
-
Verify network accessibility of the deviceDetermine if the management interface or the vulnerable service port is exposed to the network. Check firewall rules, NAT configurations, and ACLs that control access to the device.Affected if The device management interface or service is reachable from untrusted networks without authentication
A defender is affected if any MAHO-PBX NetDevancer device (Lite/Uni/Pro/Cloud, VSG Lite/Uni, or MobileGate Home/Office) is running firmware version lower than 1.11.00 and is network-accessible.

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 · scoped1.11.00
Upgrade all affected MAHO-PBX NetDevancer installations to version 1.11.00 or later. If immediate patching is not possible, restrict network access to these devices and monitor for suspicious activity.
Maho Pbx Netdevancer Firmware Ver.1.11.00 (or later) for all product variants (Netdevancer, Netdevancer VSG, Netdevancer MobileGate)
- Obtain the firmware version 1.11.00 or later from the official vendor (Maho PBX/ATE Mahoroba)
- Access the administrative interface of the NetDevancer device
- Navigate to the firmware upgrade or system maintenance section
- Upload and apply the firmware version 1.11.00
- Verify the upgrade was successful by checking the firmware version in the system information
- Restart the device if required by the upgrade process
- Confirm the vulnerability is remediated by verifying the system is running version 1.11.00 or later
