CVE-2025-59718 – Authentication Bypass – Fortinet FortiOS / FortiProxy / FortiSwitchManager (mult…

Be the first to know when new zero-days emerge:

Summary

CVE-2025-59718 is a critical improper verification of cryptographic signature vulnerability (CWE-347) in Fortinet FortiOS, FortiProxy, and FortiSwitchManager, carrying a CVSS 3.1 base score of 9.8. An unauthenticated remote attacker can bypass FortiCloud SSO login authentication by sending a crafted SAML response, potentially gaining administrative access to affected network security appliances. This vulnerability was added to CISA’s Known Exploited Vulnerabilities (KEV) catalog on December 16, 2025, and active exploitation in the wild has been confirmed.

Technical details

  • Root cause: The affected products fail to properly verify the cryptographic signature of SAML response messages (CWE-347) during FortiCloud SSO authentication processing.
  • Trigger conditions: The FortiCloud SSO login feature must be enabled on the device. While not enabled in default factory settings, it is automatically enabled when an administrator registers the device to FortiCare via the GUI — unless the "Allow administrative login using FortiCloud SSO" toggle is explicitly disabled.
  • Attack mechanism: An attacker sends a crafted SAMLResponse to the /remote/saml/login endpoint, asserting a privileged identity from a trusted issuer (e.g., https://sso.forticloud.com). Because the system does not properly validate the SAML assertion’s cryptographic signature, the forged response is accepted and the attacker is logged in without valid credentials.
  • Attack vector: Network-accessible, no authentication required, no user interaction required (AV:N/AC:L/PR:N/UI:N).
  • Impact: Successful exploitation grants an unauthenticated attacker full administrative access to the affected appliance, with high impact to confidentiality, integrity, and availability.
  • Exploitation status: Actively exploited in the wild. CISA added CVE-2025-59718 to its KEV catalog on December 16, 2025. Public proof-of-concept code is available. Reports indicate exploitation of patch bypasses following initial remediation.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
