CVSS: 6.4EPSS: 0%CPEs: 1EXPL: 0CVE-2018-25091 – urllib3: urllib3 does not remove the authorization HTTP header when following a cross-origin redirect
https://notcve.org/view.php?id=CVE-2018-25091
15 Oct 2023 — urllib3 before 1.24.2 does not remove the authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the authorization header to be exposed to unintended hosts or transmitted in cleartext. NOTE: this issue exists because of an incomplete fix for CVE-2018-20060 (which was case-sensitive). urllib3 anterior a 1.24.2 no elimina el encabezado HTTP de autorización cuando se sigue una redirección de origen cruzado (es... • https://github.com/urllib3/urllib3/commit/adb358f8e06865406d1f05e581a16cbea2136fbc • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •

https://notcve.org/view.php?id=CVE-2023-43804
04 Oct 2023 — 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 usa... • https://github.com/JawadPy/CVE-2023-43804-Exploit • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2023-40217
25 Aug 2023 — 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.

23 Aug 2023 — 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.

22 Aug 2023 — A use-after-free exists in Python through 3.9 via heappushpop in heapq. A use-after-free vulnerability was found in Python via the heappushpop function in the heapq module. This flaw allows an attacker to submit a specially crafted request, causing a service disruption that leads to a denial of service attack. It was discovered that Python incorrectly handled certain inputs. An attacker could possibly use this issue to execute arbitrary code. • https://bugs.python.org/issue39421 • CWE-416: Use After Free •

22 Aug 2023 — 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... • https://bugs.python.org/issue42103 • CWE-400: Uncontrolled Resource Consumption •

22 Aug 2023 — 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.

NOTE: this is disputed by the vendor because (1) neither 3.7 nor any other release is affected (it is a bug in some 3.12 pre-releases); (2) there are no common scenarios in which an adversary can call _asyncio._swap_current_task but does not already have the ability to call arbitrary functions; and (3) there are no common scenarios in which sensitive information, which is not al... • https://github.com/python/cpython/issues/105987 •
