CVSS: 5.3EPSS: 0%CPEs: 3EXPL: 0CVE-2023-40587 – Pyramid static view path traversal up one directory
https://notcve.org/view.php?id=CVE-2023-40587
Pyramid is an open source Python web framework. A path traversal vulnerability in Pyramid versions 2.0.0 and 2.0.1 impacts users of Python 3.11 that are using a Pyramid static view with a full filesystem path and have a `index.html` file that is located exactly one directory above the location of the static view's file system path. No further path traversal exists, and the only file that could be disclosed accidentally is `index.html`. Pyramid version 2.0.2 rejects any path that contains a null-byte out of caution. While valid in directory/file names, we would strongly consider it a mistake to use null-bytes in naming files/directories. • https://github.com/Pylons/pyramid/commit/347d7750da6f45c7436dd0c31468885cc9343c85 https://github.com/Pylons/pyramid/security/advisories/GHSA-j8g2-6fc7-q8f8 https://github.com/python/cpython/issues/106242 https://github.com/python/cpython/pull/106816 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LYSDTQ7NP5GHPQ7HBE47MBJQK7YEIYMF https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/OQIPHQTM3XE5NIEXCTQFV2J2RK2YUSMT • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 1CVE-2022-31015 – Uncaught Exception (due to a data race) leads to process termination in Waitress
https://notcve.org/view.php?id=CVE-2022-31015
Waitress is a Web Server Gateway Interface server for Python 2 and 3. Waitress versions 2.1.0 and 2.1.1 may terminate early due to a thread closing a socket while the main thread is about to call select(). This will lead to the main thread raising an exception that is not handled and then causing the entire application to be killed. This issue has been fixed in Waitress 2.1.2 by no longer allowing the WSGI thread to close the socket. Instead, that is always delegated to the main thread. • https://github.com/Pylons/waitress/commit/4f6789b035610e0552738cdc4b35ca809a592d48 https://github.com/Pylons/waitress/issues/374 https://github.com/Pylons/waitress/pull/377 https://github.com/Pylons/waitress/security/advisories/GHSA-f5x9-8jwc-25rw • CWE-248: Uncaught Exception CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2022-24761 – HTTP Request Smuggling in waitress
https://notcve.org/view.php?id=CVE-2022-24761
Waitress is a Web Server Gateway Interface server for Python 2 and 3. When using Waitress versions 2.1.0 and prior behind a proxy that does not properly validate the incoming HTTP request matches the RFC7230 standard, Waitress and the frontend proxy may disagree on where one request starts and where it ends. This would allow requests to be smuggled via the front-end proxy to waitress and later behavior. There are two classes of vulnerability that may lead to request smuggling that are addressed by this advisory: The use of Python's `int()` to parse strings into integers, leading to `+10` to be parsed as `10`, or `0x01` to be parsed as `1`, where as the standard specifies that the string should contain only digits or hex digits; and Waitress does not support chunk extensions, however it was discarding them without validating that they did not contain illegal characters. This vulnerability has been patched in Waitress 2.1.1. • https://github.com/Pylons/waitress/commit/9e0b8c801e4d505c2ffc91b891af4ba48af715e0 https://github.com/Pylons/waitress/releases/tag/v2.1.1 https://github.com/Pylons/waitress/security/advisories/GHSA-4f7p-27jc-3c36 https://lists.debian.org/debian-lts-announce/2022/05/msg00011.html https://www.debian.org/security/2022/dsa-5138 https://access.redhat.com/security/cve/CVE-2022-24761 https://bugzilla.redhat.com/show_bug.cgi?id=2065086 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 6.8EPSS: 0%CPEs: 1EXPL: 1CVE-2020-5236 – Catastrophic backtracking in regex allows Denial of Service in Waitress
https://notcve.org/view.php?id=CVE-2020-5236
Waitress version 1.4.2 allows a DOS attack When waitress receives a header that contains invalid characters. When a header like "Bad-header: xxxxxxxxxxxxxxx\x10" is received, it will cause the regular expression engine to catastrophically backtrack causing the process to use 100% CPU time and blocking any other interactions. This allows an attacker to send a single request with an invalid header and take the service offline. This issue was introduced in version 1.4.2 when the regular expression was updated to attempt to match the behaviour required by errata associated with RFC7230. The regular expression that is used to validate incoming headers has been updated in version 1.4.3, it is recommended that people upgrade to the new version of Waitress as soon as possible. • https://github.com/motikan2010/CVE-2020-5236 https://github.com/Pylons/waitress/commit/6e46f9e3f014d64dd7d1e258eaf626e39870ee1f https://github.com/Pylons/waitress/security/advisories/GHSA-73m2-3pwg-5fgc • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2019-16792 – HTTP Request Smuggling: Content-Length Sent Twice in Waitress
https://notcve.org/view.php?id=CVE-2019-16792
Waitress through version 1.3.1 allows request smuggling by sending the Content-Length header twice. Waitress would header fold a double Content-Length header and due to being unable to cast the now comma separated value to an integer would set the Content-Length to 0 internally. If two Content-Length headers are sent in a single request, Waitress would treat the request as having no body, thereby treating the body of the request as a new request in HTTP pipelining. This issue is fixed in Waitress 1.4.0. Waitress hasta la versión 1.3.1, permite el tráfico no autorizado de peticiones mediante el envío del encabezado Content-Length dos veces. • https://docs.pylonsproject.org/projects/waitress/en/latest/#security-fixes https://github.com/Pylons/waitress/commit/575994cd42e83fd772a5f7ec98b2c56751bd3f65 https://github.com/Pylons/waitress/security/advisories/GHSA-4ppp-gpcr-7qf6 https://lists.debian.org/debian-lts-announce/2022/05/msg00011.html https://www.oracle.com/security-alerts/cpuapr2022.html • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
