A improper limitation of a pathname to a restricted directory ('path traversal') vulnerability in Fortinet FortiSandbox 5.0.0 through 5.0.5, FortiSandbox 4.4.0 through 4.4.8, FortiSandbox 4.2 all versions, FortiSandbox Cloud 5.0.4, FortiSandbox PaaS 5.0.4 may allow a privileged attacker with super-admin profile and CLI access to delete an arbitrary directory via HTTP crafted requests.
AnalysisAI
Path traversal vulnerability in Fortinet FortiSandbox allows privileged super-admin users with CLI access to delete arbitrary directories on the system via crafted HTTP requests. Affects FortiSandbox 5.0.0-5.0.5, 4.4.0-4.4.8, 4.2 all versions, FortiSandbox Cloud 5.0.4, and FortiSandbox PaaS 5.0.4. CVSS 6.7 reflects high integrity and availability impact but requires authenticated super-admin privileges; no public exploit code or active KEV designation identified at time of analysis.
Technical ContextAI
The vulnerability exploits improper pathname validation in FortiSandbox's HTTP request handling, allowing directory traversal via malformed paths (CWE-22). The affected FortiSandbox products include the on-premise sandbox appliance (versions 4.2, 4.4.0-4.4.8, 5.0.0-5.0.5), cloud-delivered variant (FortiSandbox Cloud 5.0.4), and platform-as-a-service offering (FortiSandbox PaaS 5.0.4). The vulnerability requires authentication as a super-admin user with direct CLI access, meaning an attacker must already hold administrative credentials and network access to the management interface. The path traversal permits arbitrary directory deletion, enabling destruction of critical system, configuration, or data directories.
RemediationAI
Apply vendor-released patches per Fortiguard FG-IR-26-115. For FortiSandbox on-premise, upgrade to version 4.4.9 or later (4.4 branch) or 5.0.6 or later (5.0 branch); version 4.2 is end-of-life and should be migrated to a supported version. For FortiSandbox Cloud and PaaS, versions beyond 5.0.4 should be deployed automatically by Fortinet; contact Fortinet support if CloudPaaS instances remain on 5.0.4. As an interim control, restrict super-admin CLI and HTTP management access to trusted administrative networks only, disable unnecessary administrative accounts, and monitor access logs for unauthorized super-admin session activity. See https://fortiguard.fortinet.com/psirt/FG-IR-26-115 for patch availability and additional hardening guidance.
