CVE-2021-23017 – Nginx 1.20.0 - Denial of Service (DOS)
https://notcve.org/view.php?id=CVE-2021-23017
A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact. Se identificó un problema de seguridad en el solucionador de nginx, que podría permitir a un atacante que pueda falsificar paquetes UDP desde el servidor DNS para causar una sobrescritura de memoria de 1 byte, lo que causaría un bloqueo del proceso de trabajo u otro impacto potencial A flaw was found in nginx. An off-by-one error while processing DNS responses allows a network attacker to write a dot character out of bounds in a heap allocated buffer which can allow overwriting the least significant byte of next heap chunk metadata likely leading to a remote code execution in certain circumstances. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Nginx version 1.20.0 suffers from a denial of service vulnerability. • https://www.exploit-db.com/exploits/50973 https://github.com/M507/CVE-2021-23017-PoC https://github.com/ShivamDey/CVE-2021-23017 https://github.com/lakshit1212/CVE-2021-23017-PoC http://mailman.nginx.org/pipermail/nginx-announce/2021/000300.html http://packetstormsecurity.com/files/167720/Nginx-1.20.0-Denial-Of-Service.html https://lists.apache.org/thread.html/r37e6b2165f7c910d8e15fd54f4697857619ad2625f56583802004009%40%3Cnotifications.apisix.apache.org%3E https://lists.apache.org/thread.html/r4d4966221ca399 • CWE-193: Off-by-one Error •
CVE-2021-29425 – Possible limited path traversal vulnerabily in Apache Commons IO
https://notcve.org/view.php?id=CVE-2021-29425
In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like "//../foo", or "\\..\foo", the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus "limited" path traversal), if the calling code would use the result to construct a path value. En Apache Commons IO versiones anteriores a 2.7, Cuando se invoca el método FileNameUtils.normalize con una cadena de entrada inapropiada, como "//../foo" o "\\..\ foo", el resultado sería el mismo valor, por lo que posiblemente proporcionar acceso a archivos en el directorio principal, pero no más arriba (por lo tanto, salto de ruta "limited"), si el código de llamada usara el resultado para construir un valor de ruta • https://issues.apache.org/jira/browse/IO-556 https://lists.apache.org/thread.html/r01b4a1fcdf3311c936ce33d75a9398b6c255f00c1a2f312ac21effe1%40%3Cnotifications.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r0bfa8f7921abdfae788b1f076a12f73a92c93cc0a6e1083bce0027c5%40%3Cnotifications.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r0d73e2071d1f1afe1a15da14c5b6feb2cf17e3871168d5a3c8451436%40%3Ccommits.pulsar.apache.org%3E https://lists.apache.org/thread.html/r1c2f4683c35696cf6f863e3c107e37ec41305b1930dd40c17260de71%40%3Ccommits.pulsar.apache.org%3E https:/ • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
