{"id":"UBUNTU-CVE-2024-21892","details":"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the process's elevated privileges.","modified":"2026-02-04T02:29:54.360465Z","published":"2024-02-20T02:15:00Z","withdrawn":"2025-06-23T15:57:35Z","related":["CVE-2024-21892"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-21892"},{"type":"REPORT","url":"https://nodejs.org/en/blog/vulnerability/february-2024-security-releases/#code-injection-and-privilege-escalation-through-linux-capabilities-cve-2024-21892---high"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-21892"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/nodejs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.15~dfsg1-4","0.10.21~dfsg1-1","0.10.22~dfsg1-2","0.10.23~dfsg1-1","0.10.23~dfsg1-2","0.10.23~dfsg1-3","0.10.24~dfsg1-1","0.10.25~dfsg2-2","0.10.25~dfsg2-2ubuntu1","0.10.25~dfsg2-2ubuntu1.2","0.10.25~dfsg2-2ubuntu1.2+esm1","0.10.25~dfsg2-2ubuntu1.2+esm2"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-21892.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/nodejs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.25~dfsg2-2ubuntu1","4.2.2~dfsg-1","4.2.3~dfsg-1","4.2.4~dfsg-1ubuntu1","4.2.4~dfsg-2","4.2.6~dfsg-1ubuntu1","4.2.6~dfsg-1ubuntu4","4.2.6~dfsg-1ubuntu4.1","4.2.6~dfsg-1ubuntu4.2","4.2.6~dfsg-1ubuntu4.2+esm1","4.2.6~dfsg-1ubuntu4.2+esm2","4.2.6~dfsg-1ubuntu4.2+esm3"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-21892.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/nodejs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.11.4~dfsg-1ubuntu1","6.11.4~dfsg-1ubuntu2","6.12.0~dfsg-1ubuntu1","6.12.0~dfsg-2ubuntu1","6.12.0~dfsg-2ubuntu2","8.10.0~dfsg-2","8.10.0~dfsg-2ubuntu0.2","8.10.0~dfsg-2ubuntu0.3","8.10.0~dfsg-2ubuntu0.4","8.10.0~dfsg-2ubuntu0.4+esm1","8.10.0~dfsg-2ubuntu0.4+esm2","8.10.0~dfsg-2ubuntu0.4+esm3","8.10.0~dfsg-2ubuntu0.4+esm4","8.10.0~dfsg-2ubuntu0.4+esm5"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-21892.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/nodejs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["10.15.2~dfsg-2ubuntu1","10.17.0~dfsg-2ubuntu4","10.17.0~dfsg-2ubuntu6","10.19.0~dfsg-3ubuntu1","10.19.0~dfsg-3ubuntu1.1","10.19.0~dfsg-3ubuntu1.2","10.19.0~dfsg-3ubuntu1.3","10.19.0~dfsg-3ubuntu1.5","10.19.0~dfsg-3ubuntu1.6"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-21892.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/nodejs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["12.22.5~dfsg-5ubuntu1","12.22.7~dfsg-2ubuntu1","12.22.7~dfsg-2ubuntu3","12.22.9~dfsg-1ubuntu2","12.22.9~dfsg-1ubuntu3","12.22.9~dfsg-1ubuntu3.1","12.22.9~dfsg-1ubuntu3.2","12.22.9~dfsg-1ubuntu3.3","12.22.9~dfsg-1ubuntu3.4","12.22.9~dfsg-1ubuntu3.5","12.22.9~dfsg-1ubuntu3.6"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-21892.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/nodejs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["18.13.0+dfsg1-1ubuntu2","18.19.1+dfsg-2ubuntu4","18.19.1+dfsg-6ubuntu1","18.19.1+dfsg-6ubuntu2","18.19.1+dfsg-6ubuntu5"],"ecosystem_specific":{"ubuntu_priority":"medium"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-21892.json"}}],"schema_version":"1.7.3"}
