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') •
CVE-2020-1971 – EDIPARTYNAME NULL pointer dereference
https://notcve.org/view.php?id=CVE-2020-1971
The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. • https://github.com/MBHudson/CVE-2020-1971 http://www.openwall.com/lists/oss-security/2021/09/14/2 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=2154ab83e14ede338d2ede9bbe5cdfce5d5a6c9e https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=f960d81215ebf3f65e03d4d5d857fb9b666d6920 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44676 https://lists.apache.org/thread.html/r63c6f2dd363d9b514d0a4bcf624580616a679898cc14c109a49b7 • CWE-476: NULL Pointer Dereference •

CVE-2020-11022 – Potential XSS vulnerability in jQuery
https://notcve.org/view.php?id=CVE-2020-11022
In jQuery versions greater than or equal to 1.2 and before 3.5.0, passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0. En las versiones de jQuery mayores o iguales a 1.2 y anteriores a la versión 3.5.0, se puede ejecutar HTML desde fuentes no seguras, incluso después de desinfectarlo, a uno de los métodos de manipulación DOM de jQuery (es decir .html (), .append () y otros). código no seguro Este problema está corregido en jQuery 3.5.0. A Cross-site scripting (XSS) vulnerability exists in JQuery. This flaw allows an attacker with the ability to supply input to the ‘HTML’ function to inject Javascript into the page where that input is rendered, and have it delivered by the browser. jQuery version 1.2 suffers from a cross site scripting vulnerability. • https://www.exploit-db.com/exploits/49766 https://github.com/0xAJ2K/CVE-2020-11022-CVE-2020-11023 https://github.com/ossf-cve-benchmark/CVE-2020-11022 https://github.com/Snorlyd/https-nj.gov---CVE-2020-11022 http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00067.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00085.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00039.html http://packetstormsecurity.com/files/162159/jQuery-1.2& • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
