AI-suggested
To mitigate CVE-2025-59595, European organizations should immediately upgrade Absolute Secure Access to version 14.12 or later, where the vulnerability is addressed. In parallel, review and audit server configurations to identify and minimize non-default settings that may increase exposure to this vulnerability. Implement network-level protections such as firewall rules or intrusion prevention systems (IPS) to detect and block malformed packets targeting Secure Access servers. Employ network segmentation to isolate critical Secure Access infrastructure from untrusted networks, reducing the attack surface. Regularly monitor logs and network traffic for unusual patterns indicative of attempted exploitation. Establish an incident response plan specifically for denial of service scenarios affecting remote access infrastructure. Coordinate with Absolute support for any additional patches or guidance. Finally, maintain up-to-date asset inventories to ensure all instances of Secure Access are identified and remediated promptly.
Description
CVE-2025-59595 is an internally discovered denial of service vulnerability in versions of Secure Access prior to 14.12. An attacker can send a specially crafted packet to a server in a non-default configuration and cause the server to crash.
