Description

CVE-2026-8364 is a critical vulnerability in Gladinet Triofox Cloud Server Agent Access Service (GladServerAgentService.exe) that lacks authentication for critical functions accessed via specific HTTP URL paths. The service listens on TCP port 7878 and processes remote HTTP requests to paths such as /resources, /status, /sysinfo, /woshome, /Settings, /schedule, and /DavCache without requiring authentication. This allows unauthenticated remote attackers to potentially gain full control over the service. The vulnerability has a CVSS score of 9.8, indicating a high impact on confidentiality, integrity, and availability.
