CVE-2024-48931 Information

Description

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 critical system data and poses a high risk for privilege escalation or system compromise. The vulnerability occurs because the API endpoint does not validate or restrict file paths provided via the files parameter. An attacker can exploit this by manipulating the file path to access sensitive files outside the intended directory. As of time of publication no known patched versions are available.
