Node.js 14 and 3 others: Denial of Service (CWE-400)
CVE-2021-22883 is fixed in 12 products on 2 platforms, first by Node.js 10 10.24.0, released February 23, 2021. It is not reported as exploited. Patch Radar priority: High.
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.
