Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing attempts to access or extract sensitive data, revealing exposure of sensitive information to unauthorized actors.
Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.
Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.
Prevents unauthorized exposure of sensitive information by prohibiting untrusted external systems from processing or storing it.
By enforcing authorization matching prior to sharing, the control reduces the risk of exposing sensitive information to unauthorized actors.
Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.
Data mining protection mechanisms detect and block unauthorized bulk extraction of sensitive data, directly mitigating exposure to unauthorized actors.
Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Direct SSRF (CWE-918) in public-facing ZimaOS web app enables internal service interaction and sensitive data exposure.
NVD Description

internal IP addresses (e.g., 127.0.0.1, localhost, or private network ranges). This allows the attacker to interact with internal HTTP/HTTPS services that are not intended to be exposed externally or to local users. No known patch is publicly available.
Deeper analysisAI
CVE-2025-64427 is a vulnerability in ZimaOS, a fork of CasaOS that serves as an operating system for Zima devices and x86-64 systems with UEFI. Affecting version 1.5.0 and prior, the issue arises from insufficient validation or restriction of target URLs. This allows an authenticated local user to craft requests that target internal IP addresses, such as 127.0.0.1, localhost, or private network ranges. The vulnerability is associated with CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) and CWE-918 (Server-Side Request Forgery), earning a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L).
An authenticated local user can exploit this vulnerability remotely over the network with low attack complexity and no user interaction. By sending crafted requests, the attacker can interact with internal HTTP/HTTPS services not intended for external or local exposure, potentially achieving high confidentiality impacts through unauthorized access to sensitive information and low availability impacts.
The GitHub security advisory (https://github.com/IceWhaleTech/ZimaOS/security/advisories/GHSA-m8hj-7xg5-p375) documents the vulnerability, published on 2026-03-02. No known patch is publicly available, leaving affected systems reliant on network segmentation or access controls for mitigation.
