CVE-2020-24025
JavaScript vulnerability analysis and mitigation

Overview

Certificate validation in node-sass versions 2.0.0 to 4.14.1 is disabled when requesting binaries even if the user is not specifying an alternative download path. The vulnerability was discovered in 2020 and assigned CVE-2020-24025 (NVD).

Technical details

The vulnerability exists in the getBinaryUrl function where certificate validation is disabled by default when requesting binaries from github.com, even when users are not specifying an alternative download path. This occurs due to the rejectUnauthorized flag being set to false in the installation script. The vulnerability has a CVSS v3.1 Base Score of 5.3 (MEDIUM) with vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N (NVD).

Impact

The vulnerability allows attackers to perform man-in-the-middle attacks during the binary download process, as the certificate validation is disabled by default. This could potentially lead to the download of malicious binaries instead of the legitimate node-sass binaries (GitHub Discussion).

Mitigation and workarounds

Users should upgrade to versions after 4.14.1 where the certificate validation has been properly implemented. For users who need to work with self-signed certificates, it is recommended to properly import the certificates rather than disabling certificate validation entirely (GitHub Discussion).

Community reactions

The security community has expressed concerns about the implementation, with several developers on GitHub suggesting that disabling certificate validation should not be the default behavior and should instead be made optional through environment variables (GitHub Discussion).
