CVE-2026-97866 Details
Description
A weakness has been identified in Zhonglun CloudPOS 3.0. Affected by this vulnerability is an unknown functionality of the file Program.cs of the component Automatic Update. Executing a manipulation of the argument version/url/packagekey/package name can lead to channel accessible by non-endpoint. The attack can be launched remotely. Attacks of this nature are highly complex. The exploitation appears to be difficult. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A remote code execution vulnerability exists in Zhonglun CloudPOS version 3.0, specifically within the automatic update component. The issue arises because the update process relies on unencrypted HTTP communication to fetch update configuration files and packages, without any digital signature verification. This vulnerability allows attackers to intercept update requests and replace legitimate update packages with malicious ones, potentially leading to complete control over the POS terminal.
