CVE-2021-24010
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper limitation of a pathname to a restricted directory vulnerabilities in FortiSandbox 3.2.0 through 3.2.2, and 3.1.0 through 3.1.4 may allow an authenticated user to obtain unauthorized access to files and data via specifially crafted web requests.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a path traversal vulnerability in FortiSandbox's web interface. An authenticated attacker can craft malicious web requests containing directory traversal sequences (e.g., ../../../) to escape the restricted directory and access sensitive files outside the intended scope.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check FortiSandbox firmware versionLog into the FortiSandbox CLI and run the command: get system status. Alternatively, in the web UI, go to Dashboard > System Information > Firmware Version.Affected if The installed version falls within >= 3.1.0 and < 3.1.5, or >= 3.2.0 and < 3.2.3.
-
Verify web interface is enabledIn the FortiSandbox CLI, run: show system interface. Check for HTTPS or HTTP admin access configuration. In the web UI, navigate to System > Network > Interface and confirm the administrative access includes HTTPS or HTTP.Affected if The web interface (HTTPS or HTTP) is enabled and reachable on any interface.
-
Confirm authentication is possibleAttempt to log into the FortiSandbox web interface with valid admin credentials, or verify that local user accounts exist via: diagnose system admin list in the CLI.Affected if An authenticated user account exists with access to the web interface.
-
Review access logs for path traversal patternsIn the web UI, go to Log & Report > Event Logs > System Events. Search for HTTP requests containing patterns such as ../, ..%2f, or multiple forward slashes in URI paths. Alternatively, use the CLI: execute log filter category 1 and review logs for suspicious URL patterns.Affected if Any HTTP requests containing directory traversal sequences (e.g., ../../../) are present in the logs.
A system is affected if it runs FortiSandbox firmware version 3.1.0 through 3.1.4 or 3.2.0 through 3.2.2, has the web interface enabled, and has an authenticated user capable of sending web requests.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data3.1.53.2.3
Upgrade FortiSandbox to version 3.2.3 or later (for 3.2.x) or 3.1.5 or later (for 3.1.x). If immediate patching is not possible, restrict web interface access to trusted IP addresses and monitor for suspicious path traversal patterns in HTTP requests.
