Arbitrary internal service access via /v1/sys/proxy when Cloudflare Tunnel is enabled on ZimaOS

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. Prior to version 1.5.3, a proxy endpoint (/v1/sys/proxy) exposed by ZimaOS's web interface can be abused (via an externally reachable domain using a Cloudflare Tunnel) to make requests to internal localhost services. This results in unauthenticated access to internal-only endpoints and sensitive local services when the product is reachable from the Internet through a Cloudflare Tunnel. This issue has b

ZimaOS: Arbitrary Deletion of Internal System Files via API Path Manipulation

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.5.2-beta3, users are restricted from deleting internal system files or folders through the application interface. However, when interacting directly with the API, these restrictions can be bypassed. By altering the path parameter in the delete request, internal OS files and directories can be removed successfully. The backend processes these manipulated requests without validating whether

ZimaOS is vulnerable to Server-Side Request Forgery (SSRF)

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.5.0 and prior, due to insufficient validation or restriction of target URLs, an authenticated local user can craft requests that target 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.

ZimaOS: Unauthorized Creation of Files/Folders in Restricted System Directories via API

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.5.2-beta3, the application enforces restrictions in the frontend/UI to prevent users from creating files or folders in internal OS paths. However, when interacting directly with the API, the restrictions are bypass-able. By sending a crafted request targeting paths like /etc, /usr, or other sensitive system directories, the API successfully creates files or directories in locations where n

ZimaOS has Authentication Bypass via System-Level Username

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In versions up to and including 1.5.0, the application checks the validity of the username but appears to skip, misinterpret, or incorrectly validate the password when the provided username matches a known system service account. The application's login function fails to properly handle the password validation result for these users, effectively granting authenticated access to anyone who knows one of

ZimaOS Privilege Escalation using localhost calls to File API Upload

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.4.1 and all prior versions, the /v2_1/files/file/uploadV2 endpoint allows file upload from ANY USER who has access to localhost. File uploads are performed AS ROOT.

ZimaOS reads arbitrary files using localhost calls to File API Download

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.4.1 and earlier, the /v2_1/files/file/download endpoint allows file read from ANY USER who has access to localhost. File reads are performed AS ROOT.

ZimaOS vulnerable to Directory Listing via Parameter Manipulation

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.2.4 and all prior versions, the API endpoint `http://<Zima_Server_IP:PORT>/v2_1/file` in ZimaOS is vulnerable to a directory traversal attack, allowing authenticated users to list the contents of any directory on the server. By manipulating the path parameter, attackers can access sensitive system directories such as `/etc`, potentially exposing critical configuration files and increasing

ZimaOS vulnerable to Username Enumeration via API Responses

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.2.4 and all prior versions, the API endpoint `http://<Server-IP>/v1/users/login` in ZimaOS returns distinct responses based on whether a username exists or the password is incorrect. This behavior can be exploited for username enumeration, allowing attackers to determine whether a user exists in the system or not. Attackers can leverage this information in further attacks, such as credenti

ZimaOS (Installed Applications and System Information) has Unauthorized Sensitive Data Leak

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.2.4 and all prior versions, the API endpoints in ZimaOS, such as `http://<Server-IP>/v1/users/image?path=/var/lib/casaos/1/app_order.json` and `http://<Server-IP>/v1/users/image?path=/var/lib/casaos/1/system.json`, expose sensitive data like installed applications and system information without requiring any authentication or authorization. This sensitive data leak can be exploited by atta

ZimaOS Unauthenticated API Discloses Usernames

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In versions below 1.5.0, the API endpoint `http://<Server-ip>/v1/users/name` allows unauthenticated users to access sensitive information, such as usernames, without any authorization. This vulnerability could be exploited by an attacker to enumerate usernames and leverage them for further attacks, such as brute-force or phishing campaigns. As of time of publication, no known patched versions are avail

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.2.4 and all prior versions, the ZimaOS API endpoint `http://<Zima_Server_IP:PORT>/v3/file?token=<token>&files=<file_path>` is vulnerable to arbitrary file reading due to improper input validation. By manipulating the `files` parameter, authenticated users can read sensitive system files, including `/etc/shadow`, which contains password hashes for all users. This vulnerability exposes criti
