Curl 7.46.0 <= 8.4.0 Information Disclosure (CVE-2023-46218)

medium Nessus Plugin ID 187725

Language:

Synopsis

The remote host has a program that is affected by an information disclosure vulnerability.

Description

The version of Curl installed on the remote host is between 7.46.0 and 8.4.0. It is, therefore, affected by an information disclosure vulnerability. A mixed case flaw in Curl's function that verifies a given cookie domain against the Public Suffix List (PSL) allows a malicious HTTP server to set 'super cookies' in Curl, that are then passed back to more origins than what is otherwise allowed or possible. For example a cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though `co.uk` is listed as a PSL domain.

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

Solution

Upgrade Curl to version 8.5.0 or later
