{"id":"BIT-node-2021-22883","details":"Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to a denial of service attack when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.","aliases":["BIT-node-min-2021-22883","CVE-2021-22883"],"modified":"2025-04-03T14:40:37.652Z","published":"2024-03-06T11:07:12.106Z","database_specific":{"cpes":["cpe:2.3:a:nodejs:node.js:*:*:*:*:-:*:*:*","cpe:2.3:a:nodejs:node.js:*:*:*:*:lts:*:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf"},{"type":"WEB","url":"https://hackerone.com/reports/1043360"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/E4FRS5ZVK4ZQ7XIJQNGIKUXG2DJFHLO7/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F45Y7TXSU33MTKB6AGL2Q5V5ZOCNPKOG/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HSYFUGKFUSZ27M5TEZ3FKILWTWFJTFAZ/"},{"type":"WEB","url":"https://nodejs.org/en/blog/vulnerability/february-2021-security-releases/"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20210416-0001/"},{"type":"WEB","url":"https://www.oracle.com//security-alerts/cpujul2021.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuApr2021.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuoct2021.html"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-22883"}],"affected":[{"package":{"name":"node","ecosystem":"Bitnami","purl":"pkg:bitnami/node"},"ranges":[{"type":"SEMVER","events":[{"introduced":"10.0.0"},{"fixed":"10.24.0"},{"introduced":"12.0.0"},{"fixed":"12.21.0"},{"introduced":"14.0.0"},{"fixed":"14.16.0"},{"introduced":"15.0.0"},{"fixed":"15.10.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/node/BIT-node-2021-22883.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.7.3"}
