CVSS: 5.9EPSS: 0%CPEs: 19EXPL: 1CVE-2021-23336 – Web Cache Poisoning
https://notcve.org/view.php?id=CVE-2021-23336
The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before 3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter. El paquete python/cpython desde versiones 0 y anteriores a 3.6.13, desde versiones 3.7.0 y anteriores a 3.7.10, desde versiones 3.8.0 y anteriores a 3.8.8, desde versiones 3.9.0 y anteriores a 3.9.2, son vulnerables al envenenamiento de caché web por medio de urllib.parse.parse_qsl y urllib.parse.parse_qs usando un vector llamado encubrimiento de parámetros. Cuando el atacante puede separar los parámetros de la consulta usando un punto y coma (;), pueden causar una diferencia en la interpretación de la petición entre el proxy (que se ejecuta con la configuración predeterminada) y el servidor. • http://www.openwall.com/lists/oss-security/2021/02/19/4 http://www.openwall.com/lists/oss-security/2021/05/01/2 https://github.com/python/cpython/pull/24297 https://lists.apache.org/thread.html/ra8ce70088ba291f358e077cafdb14d174b7a1ce9a9d86d1b332d6367%40%3Cusers.airflow.apache.org%3E https://lists.apache.org/thread.html/rc005f4de9d9b0ba943ceb8ff5a21a5c6ff8a9df52632476698d99432%40%3Cannounce.apache.org%3E https://lists.apache.org/thread.html/rf9fa47ab66495c78bb4120b0754dd9531ca2ff0430f6685ac9b07772%40%3Cdev.mina.apache.org%3E https:/&#x • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 9.8EPSS: 3%CPEs: 15EXPL: 1CVE-2021-3177 – python: Stack-based buffer overflow in PyCArg_repr in _ctypes/callproc.c
https://notcve.org/view.php?id=CVE-2021-3177
Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to remote code execution in certain Python applications that accept floating-point numbers as untrusted input, as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used unsafely. Python versiones 3.x hasta 3.9.1, presenta un desbordamiento de búfer en la función PyCArg_repr en el archivo _ctypes/callproc.c, que puede conllevar a una ejecución de código remota en determinadas aplicaciones de Python que aceptan números de punto flotante como entrada no confiable, como es demostrado por un argumento 1e300 para c_double.from_param. Esto ocurre porque sprintf es usado de manera no segura A flaw was found in python. A stack-based buffer overflow was discovered in the ctypes module provided within Python. • https://bugs.python.org/issue42938 https://github.com/python/cpython/pull/24239 https://lists.apache.org/thread.html/rf9fa47ab66495c78bb4120b0754dd9531ca2ff0430f6685ac9b07772%40%3Cdev.mina.apache.org%3E https://lists.debian.org/debian-lts-announce/2021/04/msg00005.html https://lists.debian.org/debian-lts-announce/2022/02/msg00013.html https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BRHOCQYX3QLDGDQGTWQAUUT2G • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
