Curl 7.41.0 < 8.10.0 Security Bypass (CVE-2024-8096)

medium Nessus Plugin ID 207231

Language:

Synopsis

The remote host has a program that is affected by a security bypass vulnerability.

Description

The version of Curl installed on the remote host is between 7.41.0 prior to 8.10.0. It is, therefore, affected by a security bypass vulnerability. When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling, to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead wrongly consider the response as fine. If the returned status reports another error than 'revoked' (like for example 'unauthorized') it is not treated as a bad certficate.

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 8.10.0 or later
