Hackers Leverage Gladinet Triofox 0-Day Vulnerability to Run Malicious Code

## Gladinet Triofox Vulnerability: CVE-2025-12480

Gladinet Triofox Vulnerability: CVE-2025-12480

A critical remote code execution vulnerability identified in Gladinet Triofox, designated as CVE-2025-12480 and tracked by UNC6485, is currently being actively exploited. This vulnerability is attributed to improper host header validation within Triofox's administrative interface. Attackers exploit this flaw to access internal system configuration pages, including database reset and administrative account creation interfaces.

The exploitation process is complex, requiring a sophisticated attack chain involving over 26 HTTP requests to transition from initial access to remote code execution. This vulnerability necessitates either targeting systems with external database configurations or deploying attacker-controlled database infrastructure.

The attack initiates with bypassing the localhost header to access the AdminDatabase.aspx page. However, systems utilizing the default embedded database require additional steps for attackers to reset administrative credentials. To overcome this, attackers must log in using newly created administrative accounts and upload malicious files for execution.

To facilitate the attack without external infrastructure, VulnCheck embedded a PostgreSQL server configuration using the Go embedded-postgres package. This streamlined the attack process, allowing for new administrative credential creation and navigating ASP.NET state transitions to reach the administrative console.

File upload capabilities are established by exploiting an undocumented "Personal Home Drives" feature, which enables attackers to configure write access to system directories without authentication.

The final stage involves modifying antivirus configuration parameters to execute malicious files, achieving unauthenticated remote code execution at the SYSTEM privilege level on Windows systems.

Organizations utilizing Gladinet Triofox should prioritize immediate patching to address CVE-2025-12480. Timely remediation is crucial to prevent potential compromise of file-sharing and remote access infrastructure.
