Full Report
Multiple vulnerabilities have been discovered in Fortinet products, the most severe of which could allow for arbitrary code execution.FortiAnalyzer is a unified security operations platform that consolidates telemetry across networks, endpoints, and cloud environments.FortiClientEMS is a centralized management platform for deploying, configuring, monitoring, and enforcing security policies across numerous endpoints (computers) running the FortiClient agent.FortiDDoS is an inline, purpose-built solution that protects organizations against disruptions caused by attacks that flood a target with packets and exhaust resources, causing the network, applications, or services to be unavailable to legitimate traffic.FortiManager is a centralized management platform that lets you configure, monitor, and control multiple Fortinet security devices from a single interface.FortiNAC-F is a zero-trust network access solution that provides users with enhanced visibility into the Internet of Things (IoT) devices on their enterprise networks.FortiNDR is Fortinet's Network Detection and Response product.FortiOS is the Fortinet’s proprietary Operation System which is utilized across multiple product lines.FortiPAM provides privileged access management and control for elevated and privileged accounts, processes, and systems across the entire IT environment.FortiProxy is a secure web gateway product from Fortinet that protects users from internet-borne attacks, enforces compliance, and improves network performance.FortiSandbox is an advanced threat detection solution from Fortinet that uses sandboxing to analyze suspicious files and network traffic for advanced threats like zero-day malware and ransomware.FortiSOAR is a security orchestration, automation, and response (SOAR) solution that aims to simplify security operations for organizations.FortiSwitchManager is Fortinet's dedicated, on-premise platform for centrally managing FortiSwitch devices in large deployments.FortiVoice is a unified communications solution that combines voice, chat, conferencing, and fax into a single, secure platform for businesses and schools.FortiWeb is a web application firewall (WAF) that protects web applications and APIs from cyberattacks like SQL injection and cross-site scripting, while also helping to meet compliance requirements.Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the affected service account. Depending on the privileges associated with the service account an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Service accounts that are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

## Vulnerability Description
Multiple flaws exist across the Fortinet ecosystem. The most critical vulnerability allows for **Arbitrary Code Execution (ACE)**. While technical specifics of the injection vector are not detailed in the summary, the flaw allows an attacker to execute commands in the context of the service account running the Fortinet application. If the service account has administrative privileges, an attacker can gain full system control.
## Exploitation
- **Status:** **Exploited in the wild** (Specifically CVE-2025-61624)
- **Complexity:** Low to Medium
- **Attack Vector:** Network (Remote)
## Impact
- **Confidentiality:** High (Ability to view/exfiltrate all data)
- **Integrity:** High (Ability to change/delete data and create new accounts)
- **Availability:** High (Ability to install programs or disrupt security services)
## Remediation
### Patches
Fortinet has released updates for affected product lines. Users are urged to upgrade to the following (or later) versions:
- **FortiOS:** Upgrade to 7.4.10 or 7.6.5
- **FortiManager/Analyzer:** Upgrade to 7.4.9 or 7.6.5
- **FortiClientEMS:** Upgrade to 7.2.13 or 7.4.6
- **FortiWeb:** Upgrade to 7.6.3
- **FortiNAC-F:** Upgrade to 7.6.6
### Workarounds
- **Principle of Least Privilege:** Configure service accounts with the minimum necessary rights to limit the scope of a potential compromise.
- **Network Segmentation:** Isolate management interfaces (FortiManager/FortiAnalyzer) from the public internet.
## Detection
- **Indicators of Compromise:** Monitor for unauthorized creation of new administrative accounts or unexpected outbound traffic from security appliances.
- **Detection Methods:** Review system logs for unusual service account activity or command execution signatures. Utilize FortiGuard’s latest IPS signatures to detect exploitation attempts.
