Description

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity none, availability low.
