CVE-2025-30208 Scanner

Vite is a provider of frontend development tooling used by developers to build, configure, and optimize web applications efficiently. It offers rapid development with Hot Module Replacement capabilities and is often used for building both small projects and complex web applications worldwide. Vite is valued in the web development community for its speed and ease of use, integrating seamlessly with various JavaScript frameworks such as Vue.js and React. Organizations prioritize it for its ability to streamlining development workflows. In settings where developers use Vite to manage their frontend assets, potential vulnerabilities can have significant implications on security. As a trusted tool within the ecosystem, maintaining its security integrity is vital for users ranging from independent developers to large enterprise teams.

An Arbitrary File Read vulnerability can enable attackers to bypass file access restrictions in a system. Vulnerabilities like these arise when the system's file-access protections are improperly managed, and unauthorized access can be gained. In Vite's case, arbitrary file reading is possible due to bypassing restrictions meant to protect against accessing files outside the allowable scope. Through certain URL modifications, such as adding query string parameters like `raw??`, an attacker may exploit the server's configuration, leading to unintended data leakage. Such vulnerabilities demand careful management, especially in server configurations exposed to the network. Addressing and remediating these will protect sensitive information from unintended exposure.

Technically, this vulnerability exists because trailing separators in the URL's query strings are not adequately accounted for, particularly in regex patterns handling them. This logic flaw permits unauthorized users to append variants like `?raw??` or `?import&raw??`, therefore bypassing the protective measures intended by the `@fs` restriction. The vulnerable endpoints include paths where sensitive files might be requested, especially in networks where dev-server configurations like `--host` are public. The endpoint’s incorrect validation enables the reading of potentially sensitive files intended to be inaccessible externally. Remediation involves strict input validation and ensuring such parsing anomalies do not occur.

When exploited, arbitrary file read vulnerabilities in Vite can lead to severe implications by exposing sensitive configuration files or user information. Attackers gaining access to configuration files might understand better the internal workings of the targeted application or server. This level of insight heightens the risk of further attacks, such as privilege escalation or information disclosure. The compromise of sensitive files can further expand the attack surface to other malicious activities, including lateral movements, tampering with system files, and leveraging disclosed data for broader network compromises. Countermeasures must ensure that networked Vite environments are tightly secured and continuously monitored.
