CVE-2021-22883 – nodejs: HTTP2 'unknownProtocol' cause DoS by resource exhaustion
https://notcve.org/view.php?id=CVE-2021-22883
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. Node.js versiones anteriores a 10.24.0, 12.21.0, 14.16.0 y 15.10.0, es vulnerable a un ataque de denegación de servicio cuando son establecidos demasiados intentos de conexión con un "unknownProtocol". • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1043360 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/E4FRS5ZVK4ZQ7XIJQNGIKUXG2DJFHLO7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F45Y7TXSU33MTKB6AGL2Q5V5ZOCNPKOG https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HSYFUGKFUSZ27M5TEZ3FKILWTWFJTFAZ https://nodejs.org/en/blog/vulnerability/february-2021-security-releases& • CWE-400: Uncontrolled Resource Consumption CWE-772: Missing Release of Resource after Effective Lifetime •
CVE-2021-22884 – nodejs: DNS rebinding in --inspect
https://notcve.org/view.php?id=CVE-2021-22884
Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to DNS rebinding attacks as the whitelist includes “localhost6”. When “localhost6” is not present in /etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the “localhost6” domain. As long as the attacker uses the “localhost6” domain, they can still apply the attack described in CVE-2018-7160. Node.js versiones anteriores a 10.24.0, 12.21.0, 14.16.0 y 15.10.0, es vulnerable a unos ataques de reenlace de DNS, ya que la lista blanca incluye “localhost6”. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1069487 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/E4FRS5ZVK4ZQ7XIJQNGIKUXG2DJFHLO7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F45Y7TXSU33MTKB6AGL2Q5V5ZOCNPKOG https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HSYFUGKFUSZ27M5TEZ3FKILWTWFJTFAZ https://nodejs.org/en/blog/vulnerability/february-2021-security-releases& • CWE-20: Improper Input Validation CWE-350: Reliance on Reverse DNS Resolution for a Security-Critical Action •
