CVE-2026-1950
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 · uneditedDelta Electronics AS320T has No checking of the length of the buffer with the file name vulnerability.
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 confidenceDelta Electronics AS320T contains a buffer overflow vulnerability where the device fails to validate the length of file names before copying them into a fixed-size buffer. This could allow an attacker to send specially crafted file names that overflow the buffer, potentially leading to arbitrary code execution or denial of service.

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 the AS320T device on your networkScan your network for Delta Electronics AS320T devices. Check your network inventory, DHCP leases, or use network scanning tools to locate devices with the AS320T model designation or Delta Electronics vendor identifier.Affected if A Delta Electronics AS320T device is present on your network
-
Determine the firmware version via web interfaceAccess the device web interface (typically HTTP/HTTPS on the device IP), log in with administrative credentials, and locate the firmware version information. This is usually found in System Settings, Device Info, or About pages.Affected if The displayed firmware version is lower than 1.16
-
Check firmware version via console or SNMPIf the web interface is unavailable, access the device console via SSH or serial connection and run commands to display firmware version (commonly 'version', 'show system', or similar). Alternatively, query the device via SNMP using the Delta Electronics MIB for sysDescr or firmware version OIDs.Affected if The retrieved firmware version is lower than 1.16
-
Verify if file handling services are exposedCheck if the device has network file handling or file transfer services enabled (such as FTP, SMB, or web-based file upload features). Review the device network configuration to identify exposed services that process file names.Affected if File handling services are enabled and accessible on the network, making the buffer overflow exploitable
You are affected if a Delta Electronics AS320T device with firmware version lower than 1.16 is present and has file handling services exposed on the network.

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 · scoped1.16
Isolate the AS320T device behind a firewall with strict access controls, restrict network exposure to only necessary systems, and monitor for unusual traffic patterns. Contact Delta Electronics for firmware updates or patches addressing this vulnerability.
firmware version 1.16 or later
- 1. Navigate to Delta Electronics support site (filecenter.deltaww.com) and locate the AS320T firmware download section
- 2. Download firmware version 1.16 or later for the AS320T device
- 3. Review Delta Electronics' official firmware update documentation for the AS320T
- 4. Apply the firmware update following the vendor's standard upgrade procedure
- 5. After updating, verify the firmware version is 1.16 or higher to confirm the remediation
