An URL Redirection to Untrusted Site ('Open Redirect') vulnerability [CWE-601] vulnerability in Fortinet FortiNAC-F 7.6.0 through 7.6.5, FortiNAC-F 7.4 all versions, FortiNAC-F 7.2 all versions may allow a remote privileged attacker with system administrator role to redirect users to an arbitrary website via crafted CSV file.
AnalysisAI
Open redirect vulnerability in Fortinet FortiNAC-F allows authenticated system administrators to redirect users to arbitrary websites through crafted CSV file uploads. Affects FortiNAC-F 7.6.0-7.6.5, all 7.4.x, and all 7.2.x versions. The attack requires high privilege level (system administrator role) and user interaction (UI:R), resulting in low real-world impact despite network-accessible attack vector. No public exploit code or active exploitation confirmed.
Technical ContextAI
CWE-601 (URL Redirection to Untrusted Site) describes improper handling of URL parameters or data sources without validation against a whitelist of trusted destinations. In FortiNAC-F, the vulnerability exists in CSV file processing functionality where administrator-supplied CSV data is used to construct redirect URLs without sanitization. The affected product is Fortinet's Network Access Control appliance (FortiNAC-F), a network security solution responsible for device visibility and access control. CPE cpe:2.3:a:fortinet:fortinac-f identifies all versions of this product line. The vulnerability manifests when FortiNAC-F processes a malicious CSV file containing arbitrary URLs, which are then presented to end users without validation, allowing redirection to attacker-controlled sites.
RemediationAI
Upgrade FortiNAC-F to patched versions: 7.6.6 or later for the 7.6 branch, or apply updates per Fortinet's advisory for 7.4 and 7.2 branches. Fortinet's advisory at https://fortiguard.fortinet.com/psirt/FG-IR-26-118 contains specific patched versions for each affected release stream. As an interim control, restrict CSV file upload and processing functionality to trusted administrators only, and educate system administrators about the risks of processing untrusted CSV files that may be used in social engineering attacks against end users.
