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
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 requests. This vulnerability has been patched in version 3.0.1. • https://github.com/pallets/werkzeug/commit/f3c803b3ade485a45f12b6d6617595350c0f03e2 https://github.com/pallets/werkzeug/security/advisories/GHSA-hrfv-mqp8-q5rw https://security.netapp.com/advisory/ntap-20231124-0008 https://access.redhat.com/security/cve/CVE-2023-46136 https://bugzilla.redhat.com/show_bug.cgi?id=2246310 • CWE-400: Uncontrolled Resource Consumption CWE-407: Inefficient Algorithmic Complexity CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-25577 – Werkzeug may allow high resource usage when parsing multipart form data with many fields
https://notcve.org/view.php?id=CVE-2023-25577
Werkzeug is a comprehensive WSGI web application library. Prior to version 2.2.3, Werkzeug's multipart form data parser will parse an unlimited number of parts, including file parts. Parts can be a small amount of bytes, but each requires CPU time to parse and may use more memory as Python data. If a request can be made to an endpoint that accesses `request.data`, `request.form`, `request.files`, or `request.get_data(parse_form_data=False)`, it can cause unexpectedly high resource usage. This allows an attacker to cause a denial of service by sending crafted multipart data to an endpoint that will parse it. • https://github.com/pallets/werkzeug/commit/517cac5a804e8c4dc4ed038bb20dacd038e7a9f1 https://github.com/pallets/werkzeug/releases/tag/2.2.3 https://github.com/pallets/werkzeug/security/advisories/GHSA-xg9f-g7g7-2323 https://security.netapp.com/advisory/ntap-20230818-0003 https://www.debian.org/security/2023/dsa-5470 https://access.redhat.com/security/cve/CVE-2023-25577 https://bugzilla.redhat.com/show_bug.cgi?id=2170242 • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 3.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-23934 – Wrkzeug's incorrect parsing of nameless cookies leads to __Host- cookies bypass
https://notcve.org/view.php?id=CVE-2023-23934
Werkzeug is a comprehensive WSGI web application library. Browsers may allow "nameless" cookies that look like `=value` instead of `key=value`. A vulnerable browser may allow a compromised application on an adjacent subdomain to exploit this to set a cookie like `=__Host-test=bad` for another subdomain. Werkzeug prior to 2.2.3 will parse the cookie `=__Host-test=bad` as __Host-test=bad`. If a Werkzeug application is running next to a vulnerable or malicious subdomain which sets such a cookie using a vulnerable browser, the Werkzeug application will see the bad cookie value but the valid cookie key. • https://github.com/pallets/werkzeug/commit/cf275f42acad1b5950c50ffe8ef58fe62cdce028 https://github.com/pallets/werkzeug/releases/tag/2.2.3 https://github.com/pallets/werkzeug/security/advisories/GHSA-px8h-6qxv-m22q https://security.netapp.com/advisory/ntap-20230818-0003 https://www.debian.org/security/2023/dsa-5470 https://access.redhat.com/security/cve/CVE-2023-23934 https://bugzilla.redhat.com/show_bug.cgi?id=2170243 • CWE-20: Improper Input Validation •
