Exposure of a scanning VM's VNC service in Fortinet FortiSandbox 5.0.0-5.0.2 and 4.4.3-4.4.8 lets an unauthenticated remote attacker reach the VNC server of the sandbox virtual machines used for malware detonation via ordinary network requests. Because these VMs run and observe live malware samples, unauthorized VNC access can expose sensitive analysis sessions and potentially allow interaction with the detonation environment. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

Unauthenticated OS command injection in Fortinet FortiSandbox (on-premise, Cloud, and PaaS variants) allows remote attackers to execute arbitrary operating system commands by sending specifically crafted HTTP requests to the management interface. The flaw carries a CVSS 9.8 rating with network-reachable, no-authentication, no-user-interaction characteristics, and no public exploit identified at time of analysis. Because FortiSandbox is a security-analysis appliance handling untrusted samples, compromise undermines the integrity of malware verdicts and downstream detections.

Remote code execution in Fortinet FortiSandbox 4.4.x through 5.0.x (on-premises, Cloud, and PaaS deployments) allows unauthenticated attackers to execute arbitrary code or commands via crafted HTTP requests. This CWE-862 missing authorization flaw affects sandbox analysis appliances across multiple deployment models with CVSS 9.8 (critical) severity. Fortinet has published vendor advisory FG-IR-26-136. No CISA KEV listing or public POC identified at time of analysis, though the trivial attack complexity (AC:L) and network vector without authentication (PR:N) indicate high exploitability if technical details emerge.

Path traversal in Fortinet FortiSandbox 4.4.0-4.4.8 and 5.0.0-5.0.5 enables remote unauthenticated attackers to achieve full system compromise. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N), the vulnerability permits network-based exploitation without credentials or user interaction, leading to complete confidentiality, integrity, and availability impact. Despite critical severity, EPSS score of 0.06% (18th percentile) indicates low observed exploitation probability. No active exploitation confirmed (not in CISA KEV). SSVC framework marks it as automatable with total technical impact but no current exploitation. The incomplete CVE description (placeholder text for attack vector) suggests early disclosure; verify completeness with Fortinet advisory FG-IR-26-112.

OS command injection in Fortinet FortiSandbox 4.4.0-4.4.8 and FortiSandbox PaaS versions 21.3-23.4 enables remote unauthenticated attackers to execute arbitrary system commands with complete system compromise. CVSS 9.8 (network, low complexity, no privileges) but EPSS 0.29% (53rd percentile) suggests limited real-world exploitation observed despite maximum severity score. No active exploitation confirmed (not in CISA KEV). SSVC framework classifies as automatable with total technical impact but no known exploitation. Fortinet PSIRT advisory FG-IR-26-100 available but description incomplete (missing attack vector specifics).
