CVE-2023-43804 – `Cookie` HTTP header isn't stripped on cross-origin redirects
https://notcve.org/view.php?id=CVE-2023-43804
urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the `Cookie` HTTP header special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user. However, it is possible for a user to specify a `Cookie` header and unknowingly leak information via HTTP redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been patched in urllib3 version 1.26.17 or 2.0.5. urllib3 es una librería cliente HTTP fácil de usar para Python. urllib3 no trata el encabezado HTTP "Cookie" de manera especial ni proporciona ayuda para administrar las cookies a través de HTTP, eso es responsabilidad del usuario. Sin embargo, es posible que un usuario especifique un encabezado "Cookie" y, sin saberlo, filtre información a través de redireccionamientos HTTP a un origen diferente si ese usuario no deshabilita los redireccionamientos explícitamente. Este problema se solucionó en urllib3 versión 1.26.17 o 2.0.5. • https://github.com/JawadPy/CVE-2023-43804-Exploit https://github.com/urllib3/urllib3/commit/01220354d389cd05474713f8c982d05c9b17aafb https://github.com/urllib3/urllib3/commit/644124ecd0b6e417c527191f866daa05a5a2056d https://github.com/urllib3/urllib3/security/advisories/GHSA-v845-jxx5-vc9f https://lists.debian.org/debian-lts-announce/2023/10/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/5F5CUBAN5XMEBVBZPHFITBLMJV5FIJJ5 https://lists.fedoraproject.org/archives/list/package-announc • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2023-40217 – python: TLS handshake bypass
https://notcve.org/view.php?id=CVE-2023-40217
An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18, 3.10.x before 3.10.13, and 3.11.x before 3.11.5. It primarily affects servers (such as HTTP servers) that use TLS client authentication. If a TLS server-side socket is created, receives data into the socket buffer, and then is closed quickly, there is a brief window where the SSLSocket instance will detect the socket as "not connected" and won't initiate a handshake, but buffered data will still be readable from the socket buffer. This data will not be authenticated if the server-side TLS peer is expecting client certificate authentication, and is indistinguishable from valid TLS stream data. Data is limited in size to the amount that will fit in the buffer. • https://lists.debian.org/debian-lts-announce/2023/09/msg00022.html https://lists.debian.org/debian-lts-announce/2023/10/msg00017.html https://mail.python.org/archives/list/security-announce%40python.org/thread/PEPLII27KYHLF4AK3ZQGKYNCRERG4YXY https://security.netapp.com/advisory/ntap-20231006-0014 https://www.python.org/dev/security https://access.redhat.com/security/cve/CVE-2023-40217 https://bugzilla.redhat.com/show_bug.cgi?id=2235789 • CWE-305: Authentication Bypass by Primary Weakness •
CVE-2023-41105 – python: file path truncation at \0 characters
https://notcve.org/view.php?id=CVE-2023-41105
An issue was discovered in Python 3.11 through 3.11.4. If a path containing '\0' bytes is passed to os.path.normpath(), the path will be truncated unexpectedly at the first '\0' byte. There are plausible cases in which an application would have rejected a filename for security reasons in Python 3.10.x or earlier, but that filename is no longer rejected in Python 3.11.x. Python 3.11 os.path.normpath() function is vulnerable to path truncation if a null byte is inserted in the middle of passed path. This may result in bypass of allow lists if implemented before the verification of the path. • https://github.com/JawadPy/CVE-2023-41105-Exploit https://github.com/python/cpython/issues/106242 https://github.com/python/cpython/pull/107981 https://github.com/python/cpython/pull/107982 https://github.com/python/cpython/pull/107983 https://mail.python.org/archives/list/security-announce%40python.org/thread/D6CDW3ZZC5D444YGL3VQUY6D4ECMCQLD https://security.netapp.com/advisory/ntap-20231006-0015 https://access.redhat.com/security/cve/CVE-2023-41105 https://bugzilla.redhat.com/show_bug.cgi • CWE-158: Improper Neutralization of Null Byte or NUL Character CWE-426: Untrusted Search Path •
CVE-2022-48564 – python: DoS when processing malformed Apple Property List files in binary format
https://notcve.org/view.php?id=CVE-2022-48564
read_ints in plistlib.py in Python through 3.9.1 is vulnerable to a potential DoS attack via CPU and RAM exhaustion when processing malformed Apple Property List files in binary format. A vulnerability was found in the Python core plistlib library within the read_ints() function in the plistlib.py file. In malformed input, the implementation can be manipulated to create an argument for struct.unpack(). This issue can lead to excessive CPU and memory consumption, resulting in a MemError, as it constructs the 'format' argument for unpack(). This flaw allows an attacker to employ a binary plist input, potentially executing a denial of service (DoS) attack by exhausting CPU and RAM resources. • https://bugs.python.org/issue42103 https://lists.debian.org/debian-lts-announce/2023/10/msg00017.html https://security.netapp.com/advisory/ntap-20230929-0009 https://access.redhat.com/security/cve/CVE-2022-48564 https://bugzilla.redhat.com/show_bug.cgi?id=2249750 • CWE-400: Uncontrolled Resource Consumption •
CVE-2022-48565 – python: XML External Entity in XML processing plistlib module
https://notcve.org/view.php?id=CVE-2022-48565
An XML External Entity (XXE) issue was discovered in Python through 3.9.1. The plistlib module no longer accepts entity declarations in XML plist files to avoid XML vulnerabilities. A flaw was found in Python caused by improper handling of XML external entity (XXE) declarations by the plistlib module. By using a specially crafted XML content, an attacker could obtain sensitive information by disclosing files specified by parsing URI, and may cause denial of service by resource exhaustion. • https://bugs.python.org/issue42051 https://lists.debian.org/debian-lts-announce/2023/09/msg00022.html https://lists.debian.org/debian-lts-announce/2023/10/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AFHYAGWBFBNUGWU6XWKBHTCV5NH77MB7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BAYWJD576JUKLHCWKDLMJSUGTRDKPF3M https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KZRZRJHWLZ7MOJNPQBWGJVXMVYDC5B • CWE-611: Improper Restriction of XML External Entity Reference •
