Background
Netron is an open-source viewer for neural network models, supporting various frameworks and formats. It provides a user-friendly interface for visualizing complex model architectures. However, versions up to 9.1.2 are susceptible to a reflected cross-site scripting (XSS) vulnerability, which can be exploited through unsanitized node names.
Vulnerability Detail
The vulnerability arises from the improper sanitization of node names in the Netron desktop application. This allows an attacker to inject malicious scripts that can be executed in the context of the user's browser. The consequences include the potential for remote code execution, unauthorized access to sensitive information, and the ability to manipulate the application's behavior. Attackers could hide certain nodes, perform port scanning, or exploit existing vulnerabilities in the Chrome browser.
