CVE-2025-59692
Raw vector
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:NSummary
CVE-2025-59692 is a low-severity Incorrect Resource Transfer Between Spheres (CWE-669) vulnerability in Anagogistis (inferred from references). Its CVSS base score is 3.7 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Escape to Host (T1611); ranked at the 9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) and SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

Vulnerability Data
PureVPN client applications on Linux through September 2025 mishandle firewalling. They flush the system's existing iptables rules and apply default ACCEPT policies when connecting to a VPN server. This removes firewall rules that may have been configured manually or by…

other software (e.g., UFW, container engines, or system security policies). Upon VPN disconnect, the original firewall state is not restored. As a result, the system may become unintentionally exposed to network traffic that was previously blocked. This affects CLI 2.0.1 and GUI 2.10.0.

Mitigating Controls (NIST 800-53 r5) AI
Enforces approved information flow authorizations between system components and connected systems, directly stopping improper resource transfers across spheres.
Prevents unintended information leakage through shared system resources when crossing sphere boundaries.
Monitors and controls communications at external and key internal boundaries to block unauthorized transfers between trust domains.
Enforces logical access authorizations that limit resource transfers to only approved sphere crossings.
Separates user functionality from system management functions to avoid improper resource or behavior transfer between privilege spheres.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Least-privilege authorization policies directly constrain resource transfers across security domains.
Protecting data-in-transit can limit exposure during inter-sphere transfers but does not address control-flow or authorization errors.
Logical segmentation and access controls reduce unintended cross-sphere resource movement.

Environment separation limits unintended resource leakage between spheres.
Information-transfer rules can prevent improper resource hand-off between spheres.
Access-control policies limit unintended control over transferred resources.
Managing access rights reduces risk of unauthorized resource transfer.
Network-security controls can block improper cross-sphere transfers.
Network segregation directly limits unintended resource movement between spheres.
