CVE-2025-12480

Gladinet Triofox versions prior to 16.7.10368.56560 contain an improper access control flaw (CWE-284) that leaves the product's initial setup pages reachable without authentication even after initial configuration is complete. Because the flaw requires no privileges, user interaction, or special conditions (CVSS:3.1 AV:N/AC:L/PR:N/UI:N), a remote attacker can reach these setup pages on an internet-reachable Triofox server. By re-entering the setup flow, an attacker can reconfigure the deployment, and public reporting indicates attackers abused this to run malicious payloads via the antivirus configuration feature and install remote access tools, producing high confidentiality and integrity impact (C:H/I:H/A:N). Any organization running an affected Triofox version, whether deployed on-premises or as a cloud service, is exposed. The flaw is being actively exploited: Google/Mandiant published a public technical writeup, CISA added it to the Known Exploited Vulnerabilities catalog on 2025-11-12, and EPSS puts the 30-day exploitation probability at 90.5% (100th percentile).

What to do: Upgrade Triofox to version 16.7.10368.56560 or later per vendor instructions; where patching is not immediately possible, apply vendor mitigations, restrict access to the setup pages, and note that federal agencies must follow CISA BOD 22-01 guidance (including for cloud services) or discontinue use. Given confirmed in-the-wild exploitation, check for compromise: review the antivirus configuration for tampering, hunt for installed remote access tools or unexpected payloads, and audit accounts and configuration changes made after initial setup.
