AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions npm versions 5.7.0

Description The issue is related to the correctMkdir component of the npm package manager, which incorrectly assigns permissions for a critical resource. This could allow an attacker to bypass existing security restrictions. The problem might enable local users to bypass intended filesystem access restrictions because the ownerships of /etc and /usr directories are being changed unexpectedly.

Recommendations For npm version 5.7.0, consider restricting access to critical resources until a patch is available. As a temporary workaround, avoid using the correctMkdir component to minimize the risk of exploitation.
