Описание
On Linux, Node.js ignores certain environment variables if those may have been set by an unprivileged user while the process is running with elevated privileges with the only exception of CAP_NET_BIND_SERVICE.
Due to a bug in the implementation of this exception, Node.js incorrectly applies this exception even when certain other capabilities have been set.
This allows unprivileged users to inject code that inherits the process's elevated privileges.
A flaw was found in Node.js. On Linux, Node.js ignores certain environment variables if an unprivileged user has set them while the process is running with elevated privileges, except for CAP_NET_BIND_SERVICE. Due to a bug in the implementation of this exception, Node.js incorrectly applies this exception even when other capabilities have been set. This flaw allows unprivileged users to inject code that inherits the process's elevated privileges.
Отчет
This vulnerability is classified as an Important severity rather than Critical due to several factors. While it allows unprivileged users to inject code and potentially escalate privileges in a process running with elevated privileges, it does so under specific conditions and limitations. The vulnerability only affects Linux systems where Node.js is running with elevated privileges, and it relies on a specific bug in handling environment variables set by unprivileged users. Additionally, the impact is constrained to the Node.js environment and does not directly compromise the underlying operating system.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
