CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2024-49767 – Werkzeug possible resource exhaustion when parsing file data in forms
https://notcve.org/view.php?id=CVE-2024-49767
25 Oct 2024 — Werkzeug is a Web Server Gateway Interface web application library. Applications using `werkzeug.formparser.MultiPartParser` corresponding to a version of Werkzeug prior to 3.0.6 to parse `multipart/form-data` requests (e.g. all flask applications) are vulnerable to a relatively simple but effective resource exhaustion (denial of service) attack. A specifically crafted form submission request can cause the parser to allocate and block 3 to 8 times the upload size in main memory. There is no upper limit; a s... • https://github.com/pallets/quart/commit/5e78c4169b8eb66b91ead3e62d44721b9e1644ee • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2024-49766 – Werkzeug safe_join not safe on Windows
https://notcve.org/view.php?id=CVE-2024-49766
25 Oct 2024 — Werkzeug is a Web Server Gateway Interface web application library. On Python < 3.11 on Windows, os.path.isabs() does not catch UNC paths like //server/share. Werkzeug's safe_join() relies on this check, and so can produce a path that is not safe, potentially allowing unintended access to data. Applications using Python >= 3.11, or not using Windows, are not vulnerable. Werkzeug version 3.0.6 contains a patch. • https://github.com/pallets/werkzeug/commit/2767bcb10a7dd1c297d812cc5e6d11a474c1f092 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2024-34069
06 May 2024 — Werkzeug is a comprehensive WSGI web application library. The debugger in affected versions of Werkzeug can allow an attacker to execute code on a developer's machine under some circumstances. This requires the attacker to get the developer to interact with a domain and subdomain they control, and enter the debugger PIN, but if they are successful it allows access to the debugger even if it is only running on localhost. This also requires the attacker to guess a URL in the developer's application that will ... • https://github.com/pallets/werkzeug/commit/3386395b24c7371db11a5b8eaac0c91da5362692 • CWE-352: Cross-Site Request Forgery (CSRF) •
CVSS: 8.0EPSS: 0%CPEs: 2EXPL: 0CVE-2023-46136 – Werkzeug vulnerable to high resource usage when parsing multipart/form-data containing a large part with CR/LF character at the beginning
https://notcve.org/view.php?id=CVE-2023-46136
24 Oct 2023 — Werkzeug is a comprehensive WSGI web application library. If an upload of a file that starts with CR or LF and then is followed by megabytes of data without these characters: all of these bytes are appended chunk by chunk into internal bytearray and lookup for boundary is performed on growing buffer. This allows an attacker to cause a denial of service by sending crafted multipart data to an endpoint that will parse it. The amount of CPU time required can block worker processes from handling legitimate requ... • https://github.com/pallets/werkzeug/commit/f3c803b3ade485a45f12b6d6617595350c0f03e2 • CWE-400: Uncontrolled Resource Consumption CWE-407: Inefficient Algorithmic Complexity CWE-787: Out-of-bounds Write •
