AI-suggested
European organizations should immediately assess their exposure to affected Fortinet, Ivanti, and SAP products and prioritize patching with the latest vendor updates. For Fortinet devices, if FortiCloud SSO login is enabled, disable it temporarily via the GUI or CLI until patches are applied. Conduct thorough audits to verify whether this feature is enabled, as it is off by default. For Ivanti Endpoint Manager, upgrade to version 2024 SU4 SR1 or later to remediate stored XSS and code execution flaws. Implement strict network segmentation and access controls to limit exposure of management consoles to untrusted networks. For SAP systems, apply December 2025 security patches promptly, especially for SAP Solution Manager, Commerce Cloud, and jConnect SDK components. Employ SAP-specific security hardening guides and monitor logs for suspicious activity related to these components. Additionally, implement multi-factor authentication for administrative access, restrict administrative privileges, and conduct regular security assessments. Organizations should also monitor threat intelligence feeds for emerging exploit activity and consider deploying web application firewalls and endpoint detection solutions tuned to detect exploitation attempts. Finally, conduct user awareness training to reduce risk from social engineering that could facilitate exploitation requiring user interaction.
Description
Fortinet, Ivanti, and SAP have moved to address critical security flaws in their products that, if successfully exploited, could result in an authentication bypass and code execution. The Fortinet vulnerabilities affect FortiOS, FortiWeb, FortiProxy, and FortiSwitchManager and relate to a case of improper verification of a cryptographic signature. They are tracked as CVE-2025-59718 and
