AI-suggested

Organizations should prioritize upgrading all affected Secure Access Windows clients to version 14.12 or later to remediate the vulnerability. Network administrators should review and tighten local networking policies to minimize unnecessary adjacency between untrusted network segments and Secure Access clients. Implementing network segmentation and strict access controls can reduce the attack surface. Monitoring network traffic for unusual or malformed packets targeting Secure Access clients can help detect attempted exploitation. Additionally, deploying endpoint detection and response (EDR) solutions capable of identifying client crashes or abnormal behavior may aid in early detection. Regular vulnerability scanning and asset inventory to identify all instances of affected software versions are essential. Finally, organizations should ensure incident response plans account for potential denial-of-service scenarios affecting remote access tools.

Description

CVE-2025-59596 is a denial-of-service vulnerability in Secure Access Windows client versions 12.0 to 14.10 that is addressed in version 14.12. If a local networking policy is active, attackers on an adjacent network may be able to send a crafted packet and cause the client system to crash.
