CVSS: 7.1EPSS: 0%CPEs: 15EXPL: 1CVE-2020-8492 – python: wrong backtracking in urllib.request.AbstractBasicAuthHandler allows for a ReDoS
https://notcve.org/view.php?id=CVE-2020-8492
Python 2.7 through 2.7.17, 3.5 through 3.5.9, 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1 allows an HTTP server to conduct Regular Expression Denial of Service (ReDoS) attacks against a client because of urllib.request.AbstractBasicAuthHandler catastrophic backtracking. Python versiones 2.7 hasta 2.7.17, versiones 3.5 hasta 3.5.9, versiones 3.6 hasta 3.6.10, versiones 3.7 hasta 3.7.6 y versiones 3.8 hasta 3.8.1, permiten a un servidor HTTP conducir ataques de Denegación de Servicio de Expresión Regular (ReDoS) contra un cliente debido a un backtracking catastrófico de la clase urllib.request.AbstractBasicAuthHandler. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00003.html https://bugs.python.org/issue39503 https://github.com/python/cpython/pull/18284 https://lists.apache.org/thread.html/rdb31a608dd6758c6093fd645aea3fbf022dd25b37109b6aaea5bc0b5%40%3Ccommits.cassandra.apache.org%3E https://lists.apache.org/thread.html/rfec113c733162b39633fd86a2d0f34bf42ac35f711b3ec1835c774da%40%3Ccommits.cassandra.apache.org%3E https://lists.debian.org/debian-lts-announce/2020/07/msg00011.html https://lists.debian.org/debian-lts-announce/2023/05& • CWE-400: Uncontrolled Resource Consumption •

In Python (CPython) 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1, an insecure dependency load upon launch on Windows 7 may result in an attacker's copy of api-ms-win-core-path-l1-1-0.dll being loaded and used instead of the system's copy. Windows 8 and later are unaffected. En Python (CPython) versiones 3.6 hasta 3.6.10, 3.7 hasta 3.7.6 y 3.8 hasta 3.8.1, una carga de dependencia no segura al iniciarse en Windows 7 puede resultar en una copia del atacante de api-ms-win-core-path- l1-1-0.dll siendo cargada y usada en lugar de la copia del sistema.

CVSS: 6.5EPSS: 0%CPEs: 5EXPL: 0CVE-2019-18348 – python: CRLF injection via the host part of the url passed to urlopen()
https://notcve.org/view.php?id=CVE-2019-18348
An issue was discovered in urllib2 in Python 2.x through 2.7.17 and urllib in Python 3.x through 3.8.0. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the host component of a URL) followed by an HTTP header. This is similar to the CVE-2019-9740 query string issue and the CVE-2019-9947 path string issue. (This is not exploitable when glibc has CVE-2016-10739 fixed.). This is fixed in: v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1; v3.6.11, v3.6.11rc1, v3.6.12; v3.7.8, v3.7.8rc1, v3.7.9; v3.8.3, v3.8.3rc1, v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00041.html https://bugs.python.org/issue30458#msg347282 https://bugzilla.redhat.com/show_bug.cgi?id=1727276 https://lists.debian.org/debian-lts-announce/2020/07/msg00011.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4X3HW5JRZ7GCPSR7UHJOLD7AWLTQCDVR https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/A5NSAX4SC3V64PGZUPH7PRDLSON34Q5A https://lists.fedoraproject.org/archives&#x • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •

https://notcve.org/view.php?id=CVE-2019-17514
library/glob.html in the Python 2 and 3 documentation before 2016 has potentially misleading information about whether sorting occurs, as demonstrated by irreproducible cancer-research results. NOTE: the effects of this documentation cross application domains, and thus it is likely that security-relevant code elsewhere is affected. This issue is not a Python implementation bug, and there are no reports that NMR researchers were specifically relying on library/glob.html. In other words, because the older documentation stated "finds all the pathnames matching a specified pattern according to the rules used by the Unix shell," one might have incorrectly inferred that the sorting that occurs in a Unix shell also occurred for glob.glob. There is a workaround in newer versions of Willoughby nmr-data_compilation-p2.py and nmr-data_compilation-p3.py, which call sort() directly. • https://bugs.python.org/issue33275 https://github.com/bminor/bash/blob/ac50fbac377e32b98d2de396f016ea81e8ee9961/pathexp.c#L380 https://github.com/bminor/bash/blob/ac50fbac377e32b98d2de396f016ea81e8ee9961/pathexp.c#L405 https://pubs.acs.org/doi/full/10.1021/acs.orglett.9b03216 https://pubs.acs.org/doi/suppl/10.1021/acs.orglett.9b03216/suppl_file/ol9b03216_si_002.zip https://security.netapp.com/advisory/ntap-20191107-0005 https://twitter.com/LucasCMoore/status/1181615421922824192 https://twitter.com/chris_ • CWE-682: Incorrect Calculation •
CVSS: 6.1EPSS: 0%CPEs: 10EXPL: 2CVE-2019-16935 – python: XSS vulnerability in the documentation XML-RPC server in server_title field
https://notcve.org/view.php?id=CVE-2019-16935
The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary JavaScript can be delivered to clients that visit the http URL for this server. La documentación del servidor XML-RPC en Python versiones hasta 2.7.16, versiones 3.x hasta 3.6.9 y versiones 3.7.x hasta 3.7.4, presenta una vulnerabilidad de tipo XSS por medio del campo server_title. Esto ocurre en Lib/DocXMLRPCServer.py en Python versión 2.x, y en Lib/xmlrpc/server.py en Python versión 3.x. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00062.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00063.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html https://bugs.python.org/issue38243 https://github.com/python/cpython/blob/35c0809158be7feae4c4f877a08b93baea2d8291/Lib/xmlrpc/server.py#L897 htt • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
