Apple Xcode < 4.4 Multiple Vulnerabilities (Mac OS X) (BEAST)

Medium Nessus Plugin ID 61413

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3.4

Synopsis

The remote host has an application installed that is affected by multiple vulnerabilities.

Description

The remote Mac OS X host has a version of Apple Xcode installed that is prior to 4.4. It is, therefore, affected by multiple vulnerabilities :

- An information disclosure vulnerability, known as BEAST, exists in the SSL 3.0 and TLS 1.0 protocols due to a flaw in the way the initialization vector (IV) is selected when operating in cipher-block chaining (CBC) modes. A man-in-the-middle attacker can exploit this to obtain plaintext HTTP header data, by using a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses the HTML5 WebSocket API, the Java URLConnection API, or the Silverlight WebClient API.
(CVE-2011-3389)

- An information disclosure vulnerability exists that may allow a specially crafted App Store application to read entries in the keychain. (CVE-2012-3698)

Solution

Upgrade to Apple Xcode version 4.4 or later.
