CVE-2026-8364
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 · uneditedGladinet Triofox Cloud Server Agent Access Service (GladServerAgentService.exe) listens on TCP port 7878 and processes remote HTTP messages with URL paths starting with /resources, /status, /sysinfo, /woshome, /Settings, /schedule, or /DavCache.
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 confidenceGladinet Triofox Cloud Server Agent (GladServerAgentService.exe) exposes an HTTP service on TCP port 7878 that handles multiple URL endpoints including /resources, /status, /sysinfo, /woshome, /Settings, /schedule, and /DavCache. The critical CVSS score indicates this unauthenticated HTTP interface is likely vulnerable to remote code execution or severe authentication bypass.

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.
-
Verify GladServerAgentService.exe is installed and runningOpen Windows Task Manager or run 'tasklist /FI "IMAGENAME eq GladServerAgentService.exe"' in command prompt to see if the service process is activeAffected if The process GladServerAgentService.exe is running on the system
-
Confirm TCP port 7878 is listeningRun 'netstat -an | findstr :7878' or use PowerShell 'Get-NetTCPConnection -LocalPort 7878 -State Listen' to check if the service is bound to port 7878Affected if Port 7878 is in LISTENING state and accepting connections
-
Test unauthenticated HTTP endpoint accessUse a web browser or curl to request http://localhost:7878/status or http://localhost:7878/sysinfo without providing any credentialsAffected if The endpoint returns HTTP 200 and exposes system information without authentication
-
Check network exposure of port 7878Run 'netstat -ano | findstr :7878' to identify listening addresses. If listening on 0.0.0.0 or ::, the service is exposed to all network interfaces. Verify with 'Test-NetConnection -ComputerName localhost -Port 7878' from external hostsAffected if Port 7878 is bound to 0.0.0.0 or :: and accessible from non-localhost addresses
-
Compare installed version to available releasesRight-click GladServerAgentService.exe, select Properties, then Details to view File Version, or query registry under HKLM\Software\Gladinet\Triofox for version keys. Contact vendor or check release notes to determine if current version is older than patched releasesAffected if Installed version is older than the latest patched version provided by Gladinet
The system is affected if GladServerAgentService.exe is running with port 7878 exposed and accessible without authentication 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.
From vendor dataImmediately restrict network access to port 7878 via firewall rules to block external traffic, and contact Gladinet for vendor-supplied patches addressing this critical vulnerability in the Triofox Cloud Server Agent.
