Security readout for executives and security teams
Plain-English summary
CVE-2023-45587 is a low-severity cross-site scripting issue in Fortinet FortiSandbox. An attacker with some access may be able to send crafted HTTP requests that cause unauthorized code or commands to run in a web page context, with limited integrity impact.
Executive priority
Handle through normal vulnerability management unless the appliance is broadly accessible or contains many low-trust users. The expected impact is limited, but security infrastructure should not remain on affected builds unnecessarily.
Technical view
The issue is CWE-79 improper input neutralization during web page generation. It affects FortiSandbox 4.4.0 through 4.4.2, all 4.2, 4.0, 3.2, and 3.1 releases. CVSS 3.1 is 3.4: network reachable, low complexity, low privileges required, user interaction required, integrity impact only.
Likely exposure
Exposure is limited to organizations running the affected FortiSandbox versions. Risk is higher where the FortiSandbox management interface is reachable by many authenticated users or reachable from less trusted networks.
Exploitation context
The bundle does not identify CISA KEV listing or active exploitation. The CVSS vector includes functional exploit maturity, but the provided sources do not establish real-world exploitation.
Researcher notes
Evidence supports XSS with PR:L and UI:R requirements, not unauthenticated remote compromise. The source bundle does not include endpoint details, proof-of-concept behavior, or fixed version numbers, so validation should stay inventory- and advisory-driven.
Mitigation direction
- Check Fortinet advisory FG-IR-23-360 for fixed releases and upgrade guidance.
- Prioritize upgrade or replacement of affected FortiSandbox versions.
- Restrict FortiSandbox administrative access to trusted networks and users.
- Review user roles and remove unnecessary low-privilege access.
- Monitor FortiSandbox web access logs for unusual crafted HTTP requests.
Validation and detection
- Inventory FortiSandbox appliances and record exact software versions.
- Compare versions against the affected ranges in the CVE record.
- Confirm whether Fortinet's advisory lists a fixed target version for each appliance.
- Verify management interfaces are not exposed to untrusted networks.
- Review recent administrative web logs for suspicious request patterns.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
