In Python before 3.10.3 on Windows, local users can gain privileges because the search path is inadequately secured. The installer may allow a local attacker to add user-writable directories to the system search path. To exploit, an administrator must have installed Python for all users and enabled PATH entries. A non-administrative user can trigger a repair that incorrectly adds user-writable paths into PATH, enabling search-path hijacking of other users and system services. This affects Python (CPython) through 3.7.12, 3.8.x through 3.8.12, 3.9.x through 3.9.10, and 3.10.x through 3.10.2. • https://mail.python.org/archives/list/security-announce%40python.org/thread/657Z4XULWZNIY5FRP3OWXHYKUSIH6DMN https://security.netapp.com/advisory/ntap-20220419-0005 • CWE-426: Untrusted Search Path •

A flaw was found in Python, specifically within the urllib.parse module. This module helps break Uniform Resource Locator (URL) strings into components. The issue involves how the urlparse method does not sanitize input and allows characters like '\r' and '\n' in the URL path. This flaw allows an attacker to input a crafted URL, leading to injection attacks. This flaw affects Python versions prior to 3.10.0b1, 3.9.5, 3.8.11, 3.7.11 and 3.6.14. • https://bugs.python.org/issue43882 https://lists.debian.org/debian-lts-announce/2023/09/msg00022.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CSD2YBXP3ZF44E44QMIIAR5VTO35KTRB https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UDBDBAU6HUPZHISBOARTXZ5GKHF2VH5U https://security.gentoo.org/glsa/202305-02 https://security.netapp.com/advisory/ntap-20220225-0009 https://www.oracle.com/security-alerts/cpuapr2022.html https://access. • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability. Se presenta un fallo en la clase AbstractBasicAuthHandler de urllib. Un atacante que controle un servidor HTTP malicioso al que se conecte un cliente HTTP (como un navegador web), podría desencadenar una Denegación de Servicio por Expresión Regular (ReDOS) durante una petición de autenticación con una carga útil especialmente diseñada que sea enviada por el servidor al cliente. • https://bugs.python.org/issue43075 https://bugzilla.redhat.com/show_bug.cgi?id=1995234 https://github.com/python/cpython/commit/7215d1ae25525c92b026166f9d5cac85fb https://github.com/python/cpython/pull/24391 https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://security.netapp.com/advisory/ntap-20220407-0001 https://ubuntu.com/security/CVE-2021-3733 https://access.redhat.com/security/cve/CVE-2021-3733 • CWE-400: Uncontrolled Resource Consumption •

There's a flaw in Python 3's pydoc. A local or adjacent attacker who discovers or is able to convince another local or adjacent user to start a pydoc server could access the server and use it to disclose sensitive information belonging to the other user that they would not normally be able to access. The highest risk of this flaw is to data confidentiality. This flaw affects Python versions before 3.8.9, Python versions before 3.9.3 and Python versions before 3.10.0a7. Se presenta un fallo en pydoc de Python versión 3. • https://bugzilla.redhat.com/show_bug.cgi?id=1935913 https://lists.debian.org/debian-lts-announce/2021/04/msg00005.html https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/25HVHLBGO2KNPXJ3G426QEYSSCECJDU5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BF2K7HEWADHN6P52R3QLIOX27U3DJ4HI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message&#x • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

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') •
