CVE-2014-1263:CVE-2014-1263 describes a vulnerability in curl and libcurl versions 7.27.0 through 7.35.0, specifically affecting Apple OS X 10.9.x before version 10.9.2. This vulnerability allows man-in-the-middle attackers to spoof servers by using an arbitrary valid certificate when accessing a URL with a numerical IP address.

Description Preview

The vulnerability in question arises from the fact that when using the SecureTransport/Darwinssl backend, curl and libcurl versions 7.27.0 through 7.35.0 do not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate. This oversight enables attackers to carry out man-in-the-middle attacks by presenting a valid certificate for a different domain than the one being accessed, particularly when the URL uses a numerical IP address.

Overview

This vulnerability affects curl and libcurl versions 7.27.0 through 7.35.0 when utilizing the SecureTransport/Darwinssl backend on Apple OS X 10.9.x before version 10.9.2. It allows malicious actors to spoof servers by leveraging an arbitrary valid certificate when accessing URLs with numerical IP addresses.

Remediation

To address this vulnerability, users are advised to update their systems to a version of curl or libcurl beyond 7.35.0, specifically after the release of Apple OS X 10.9.2. By ensuring that the server hostname verification process is correctly implemented, the risk of man-in-the-middle attacks exploiting this flaw can be mitigated.
