CVE-2024-31491
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 · uneditedA client-side enforcement of server-side security vulnerability in Fortinet FortiSandbox 4.4.0 through 4.4.4, FortiSandbox 4.2.1 through 4.2.6 allows attacker to execute unauthorized code or commands via HTTP 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 · moderate confidenceCommand injection vulnerability in FortiSandbox allows remote attackers to execute arbitrary code or commands via crafted HTTP requests. The vulnerability stems from insufficient input validation where client-supplied data is not properly sanitized before being processed server-side, enabling attackers to inject OS-level commands through HTTP parameters.

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.
-
Confirm FortiSandbox is deployedInventory your environment for FortiSandbox appliances or virtual instances. Check cloud inventories, virtualization platforms, or physical hardware logs.Affected if FortiSandbox is present in the environment
-
Identify installed FortiSandbox versionLog into the FortiSandbox administrative interface or CLI and retrieve the system version. In CLI, use 'get system status' or check System > Settings in the GUI.Affected if Version is >=4.2.0 and <4.2.7, OR >=4.4.0 and <4.4.5
-
Verify management interface accessibilityReview network firewall rules and access control lists to determine if the FortiSandbox HTTP management interface (port 443 or 80) is reachable from untrusted networks.Affected if Management interface is exposed to the internet or untrusted internal networks
-
Examine HTTP access logs for suspicious requestsReview FortiSandbox HTTP access logs or WAF logs for unusual patterns in HTTP parameters that may indicate command injection attempts, such as shell metacharacters (| ; $ ( ) & > <) in query strings or POST bodies.Affected if Logs show suspicious HTTP requests containing command injection patterns
You are affected if FortiSandbox is running a version between 4.2.0-4.2.6 or 4.4.0-4.4.4 AND the management interface is network-accessible to potential attackers.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped4.2.74.4.5
Upgrade FortiSandbox to version 4.4.5 or later (for 4.4.x branch) or 4.2.7 or later (for 4.2.x branch). If immediate patching is not feasible, restrict network access to the management interface and implement WAF rules to filter malicious HTTP request patterns.
FortiSandbox 4.2.7 or 4.4.5 (upgrade to the latest available version in your respective branch)
- Backup the current FortiSandbox configuration and data before starting the upgrade process
- Access the FortiSandbox administrative interface or CLI
- Navigate to System > Firmware or use the 'execute system firmware upgrade' command
- Download the appropriate firmware version from Fortinet support portal: 4.2.7 for 4.2.x branch or 4.4.5 for 4.4.x branch
- Upload the firmware file and initiate the upgrade process
- Allow the system to reboot and complete the upgrade
- After reboot, verify the new firmware version under System > Dashboard > Status
- Confirm the vulnerability is resolved by checking that HTTP requests cannot execute unauthorized code or commands
