Details of the vulnerabilities are as follows: Tactic: Initial Access (TA0001): Technique: Exploit Public-Facing Application (T1190):

An unverified password change vulnerability in FortiSwitch GUI may allow a remote unauthenticated attacker to modify admin passwords via a specially crafted request. (CVE-2024-48887)
An improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in FortiIsolator may allow a privileged attacker with super-admin profile and CLI access to execute unauthorized code via specifically crafted HTTP requests. (CVE-2024-54024)
A improper restriction of communication channel to intended endpoints vulnerability in FortiOS, FortiProxy, FortiManager, FortiAnalyzer, FortiVoice and FortiWeb may allow an unauthenticated attacker in a man-in-the-middle position to impersonate the management device (FortiCloud server or/and in certain conditions, FortiManager), via intercepting the FGFM authentication request between the management device and the managed device (CVE-2024-26013, CVE-2024-50565)

Details of lower severity vulnerabilities:

An improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in FortiIsolator CLI may allow a privileged attacker to execute unauthorized code or commands via crafted CLI requests. (CVE-2024-54025)
An Improper Output Neutralization for Logs vulnerability in FortiManager and FortiAnalyzer may allow an unauthenticated remote attacker to pollute the logs via crafted login requests. (CVE-2024-52962)
An insufficiently protected credentials vulnerability in FortiOS may allow a privileged authenticated attacker to retrieve LDAP credentials via modifying the LDAP server IP address in the FortiOS configuration to point to a malicious attacker-controlled server. (CVE-2024-32122)
An Incorrect User Management vulnerability in FortiWeb widgets dashboard may allow an authenticated attacker with at least read-only admin permission to perform operations on the dashboard of other administrators via crafted requests. (CVE-2024-46671)
An improper neutralization of input during web page generation ('Cross-site Scripting') vulnerability in FortiClient may allow the EMS administrator to send messages containing javascript code. (CVE-2025-22855)
An Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in FortiWeb endpoint may allow an authenticated admin to access and modify the filesystem via crafted requests. (CVE-2025-25254)

Successful exploitation of these vulnerabilities could allow an attacker to execute remote code in the context of the system. Depending on the privileges associated with the system, an attacker could then install programs; view, change, or delete data. RECOMMENDATIONS: We recommend the following actions be taken:

Apply appropriate updates provided by Fortinet to vulnerable systems immediately after appropriate testing. (M1051: Update Software)
- Safeguard 7.1 : Establish and Maintain a Vulnerability Management Process: Establish and maintain a documented vulnerability management process for enterprise assets. Review and update documentation annually, or when significant enterprise changes occur that could impact this Safeguard.
- Safeguard 7.2: Establish and Maintain a Remediation Process: Establish and maintain a risk-based remediation strategy documented in a remediation process, with monthly, or more frequent, reviews.
- Safeguard 7.4: Perform Automated Application Patch Management: Perform application updates on enterprise assets through automated patch management on a monthly, or more frequent, basis.
- Safeguard 7.5 : Perform Automated Vulnerability Scans of Internal Enterprise Assets: Perform automated vulnerability scans of internal enterprise assets on a quarterly, or more frequent, basis. Conduct both authenticated and unauthenticated scans, using a SCAP-compliant vulnerability scanning tool.
- Safeguard 7.7: Remediate Detected Vulnerabilities: Remediate detected vulnerabilities in software through processes and tooling on a monthly, or more frequent, basis, based on the remediation process.
- Safeguard 12.1: Ensure Network Infrastructure is Up-to-Date: Ensure network infrastructure is kept up-to-date. Example implementations include running the latest stable release of software and/or using currently supported network-as-a-service (NaaS) offerings. Review software versions monthly, or more frequently, to verify software support.
- Safeguard 18.1: Establish and Maintain a Penetration Testing Program: Establish and maintain a penetration testing program appropriate to the size, complexity, and maturity of the enterprise. Penetration testing program characteristics include scope, such as network, web application, Application Programming Interface (API), hosted services, and physical premise controls; frequency; limitations, such as acceptable hours, and excluded attack types; point of contact information; remediation, such as how findings will be routed internally; and retrospective requirements.
- Safeguard 18.2: Perform Periodic External Penetration Tests: Perform periodic external penetration tests based on program requirements, no less than annually. External penetration testing must include enterprise and environmental reconnaissance to detect exploitable information. Penetration testing requires specialized skills and experience and must be conducted through a qualified party. The testing may be clear box or opaque box.
- Safeguard 18.3: Remediate Penetration Test Findings: Remediate penetration test findings based on the enterprise’s policy for remediation scope and prioritization.
Apply the Principle of Least Privilege to all systems and services. Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack. (M1026: Privileged Account Management)
- Safeguard 4.7: Manage Default Accounts on Enterprise Assets and Software: Manage default accounts on enterprise assets and software, such as root, administrator, and other pre-configured vendor accounts. Example implementations can include: disabling default accounts or making them unusable.
- Safeguard 5.5: Establish and Maintain an Inventory of Service Accounts: Establish and maintain an inventory of service accounts. The inventory, at a minimum, must contain department owner, review date, and purpose. Perform service account reviews to validate that all active accounts are authorized, on a recurring schedule at a minimum quarterly, or more frequently.
Vulnerability scanning is used to find potentially exploitable software vulnerabilities to remediate them. (M1016: Vulnerability Scanning)
- Safeguard 16.13: Conduct Application Penetration Testing: Conduct application penetration testing. For critical applications, authenticated penetration testing is better suited to finding business logic vulnerabilities than code scanning and automated security testing. Penetration testing relies on the skill of the tester to manually manipulate an application as an authenticated and unauthenticated user.
Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Configure separate virtual private cloud (VPC) instances to isolate critical cloud systems. (M1030: Network Segmentation)
- Safeguard 12.2: Establish and Maintain a Secure Network Architecture: Establish and maintain a secure network architecture. A secure network architecture must address segmentation, least privilege, and availability, at a minimum.
Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring. (M1050: Exploit Protection)
- Safeguard 10.5: Enable Anti-Exploitation Features: Enable anti-exploitation features on enterprise assets and software, where possible, such as Microsoft® Data Execution Prevention (DEP), Windows® Defender Exploit Guard (WDEG), or Apple® System Integrity Protection (SIP) and Gatekeeper™.
