CVSS: 5.3EPSS: 0%CPEs: 10EXPL: 0CVE-2021-4189 – python: ftplib should not use the host from the PASV response
https://notcve.org/view.php?id=CVE-2021-4189
A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which otherwise would not have been possible. Se ha encontrado un fallo en Python, concretamente en la biblioteca del cliente FTP (File Transfer Protocol) en modo PASV (pasivo). • https://access.redhat.com/security/cve/CVE-2021-4189 https://bugs.python.org/issue43285 https://bugzilla.redhat.com/show_bug.cgi?id=2036020 https://github.com/python/cpython/commit/0ab152c6b5d95caa2dc1a30fa96e10258b5f188e https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://python-security.readthedocs.io/vuln/ftplib-pasv.html https://security-tracker.debian.org/tracker/CVE-2021-4189 https://security.netapp • CWE-252: Unchecked Return Value •
CVSS: 8.2EPSS: 0%CPEs: 71EXPL: 2CVE-2018-25032 – zlib: A flaw found in zlib when compressing (not decompressing) certain inputs
https://notcve.org/view.php?id=CVE-2018-25032
zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. zlib versiones anteriores a 1.2.12 permite la corrupción de memoria al desinflar (es decir, al comprimir) si la entrada tiene muchas coincidencias distantes An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application. • http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/38 http://www.openwall.com/lists/oss-security/2022/03/25/2 http://www.openwall.com/lists/oss-security/2022/03/26/1 https://cert-portal.siemens.com/productcert/pdf/ssa-333517.pdf https://github.com/madler/zlib/commit/5c44459c3b28a9bd3283aaceab7c615f8020c531 https://github.com/madler/zlib/compare/v1.2.11...v1.2.12 https://github.com& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
CVSS: 7.0EPSS: 0%CPEs: 13EXPL: 0CVE-2022-26488
https://notcve.org/view.php?id=CVE-2022-26488
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 •
CVSS: 7.5EPSS: 0%CPEs: 21EXPL: 1CVE-2022-0391 – python: urllib.parse does not sanitize URLs containing ASCII newline and tabs
https://notcve.org/view.php?id=CVE-2022-0391
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') •

https://notcve.org/view.php?id=CVE-2021-3733
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 •
