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-2021-26291 – block repositories using http by default
https://notcve.org/view.php?id=CVE-2021-26291
Apache Maven will follow repositories that are defined in a dependency’s Project Object Model (pom) which may be surprising to some users, resulting in potential risk if a malicious actor takes over that repository or is able to insert themselves into a position to pretend to be that repository. Maven is changing the default behavior in 3.8.1+ to no longer follow http (non-SSL) repository references by default. More details available in the referenced urls. If you are currently using a repository manager to govern the repositories used by your builds, you are unaffected by the risks present in the legacy behavior, and are unaffected by this vulnerability and change to default behavior. See this link for more information about repository management: https://maven.apache.org/repository-management.html Apache Maven seguirá los repositorios que se definen en el Project Object Model (pom) de una dependencia, lo que puede resultar sorprendente para algunos usuarios, resultando en un riesgo potencial si un actor malicioso se hace cargo de ese repositorio o es capaz de insertarse en una posición para fingir ser ese repositorio. • http://www.openwall.com/lists/oss-security/2021/04/23/5 https://lists.apache.org/thread.html/r0556ce5db7231025785477739ee416b169d8aff5ee9bac7854d64736%40%3Cannounce.apache.org%3E https://lists.apache.org/thread.html/r06db4057b74e0598a412734f693a34a8836ac6f06d16d139e5e1027c%40%3Cdev.maven.apache.org%3E https://lists.apache.org/thread.html/r07a89b32783f73bda6903c1f9aadeb859e5bef0a4daed6d87db8e4a9%40%3Cissues.karaf.apache.org%3E https://lists.apache.org/thread.html/r08a401f8c98a99f68d061fde6e6659d695f28d60fe4f0413bcb355b0%40%3Ccommits.druid.apache.org%3E https://lists • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-346: Origin Validation Error •
