high Nessus Plugin ID 201581

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of python-werkzeug installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-46136 advisory.

 - 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. (CVE-2023-46136)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
