RaspberryMatic RCE via HMIPServer.jar before 3.75.6.20240316
CVE-2024-24578 Published on March 18, 2024
RaspberryMatic Unauthenticated Remote Code Execution vulnerability through HMServer File Upload
RaspberryMatic is an open-source operating system for HomeMatic internet-of-things devices. RaspberryMatic / OCCU prior to version 3.75.6.20240316 contains a unauthenticated remote code execution (RCE) vulnerability, caused by multiple issues within the Java based `HMIPServer.jar` component. RaspberryMatric includes a Java based `HMIPServer`, that can be accessed through URLs starting with `/pages/jpages`. The `FirmwareController` class does however not perform any session id checks, thus this feature can be accessed without a valid session. Due to this issue, attackers can gain remote code execution as root user, allowing a full system compromise. Version 3.75.6.20240316 contains a patch.
Vulnerability Analysis
CVE-2024-24578 is exploitable with network access, and does not require authorization privileges or user interaction. This vulnerability is considered to have a low attack complexity. An automatable proof of concept (POC) exploit exists. The potential impact of an exploit of this vulnerability is considered to be critical as this vulnerability has a high impact to the confidentiality, integrity and availability of this component.
Weakness Types
Relative Path Traversal
The software uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. This allows attackers to traverse the file system to access files or directories that are outside of the restricted directory.
Missing Authentication for Critical Function
The software does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
