Technical Details of CVE-2022-46171

This section covers specific technical details related to the CVE.

Vulnerability Description

The issue arises from the filesystem glob pattern wildcards used in Tauri, which allow for path traversal beyond the intended directories.

Affected Systems and Versions

Tauri versions from >= 1.0.0 to < 1.0.8, >= 1.1.0 to < 1.1.3, >= 1.2.0 to < 1.2.3, and >= 2.0.0-alpha.0 to < 2.0.0-alpha.2 are affected by this vulnerability.

Exploitation Mechanism

The path traversal vulnerability can be exploited by manipulating file paths with the wildcard characters in a way that exposes unintended directories.

Mitigation and Prevention

To address CVE-2022-46171, follow these mitigation strategies:

Immediate Steps to Take

Update Tauri to the latest patched version to mitigate the risk of path traversal vulnerabilities. Be sure to apply all relevant security updates promptly.

Long-Term Security Practices

Implement secure coding practices to prevent path traversal vulnerabilities in your applications. Regularly review and update your software dependencies to include the latest security patches.

Patching and Updates

Monitor for security advisories from Tauri and apply patches promptly to address known vulnerabilities and improve the overall security posture of your systems.
