Detailsinfo

A vulnerability was found in Apple Mac OS X up to 10.11.0 (Operating System). It has been rated as critical. This issue affects an unknown function of the component Bom. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Directory traversal vulnerability in the BOM (aka Bill of Materials) component in Apple iOS before 9.1, OS X before 10.11.1, and watchOS before 2.0.1 allows remote attackers to execute arbitrary code via a crafted CPIO archive.

The weakness was published 10/21/2015 by Mark Dowd with Azimuth Security as HT205375 as confirmed advisory (Website). The advisory is shared at support.apple.com. The identification of this vulnerability is CVE-2015-7006 since 09/16/2015. The exploitation is known to be difficult. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1006 for this issue. The advisory points out:

A file traversal vulnerability existed in the handling of CPIO archives. This issue was addressed through improved validation of metadata.

The vulnerability scanner Nessus provides a plugin with the ID 86654 (Mac OS X < 10.11.1 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 124172 (Apple Mac OS X v10.11.1 Not Installed (APPLE-SA-2015-10-21-4)).
