Apple iOS up to 6.1.4 IPSec input validation

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability, which was classified as critical, has been found in Apple iOS up to 6.1.4 (Smartphone Operating System). This issue affects an unknown function of the component IPSec. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, and integrity. The summary by CVE is:

The IPSec implementation in Apple Mac OS X before 10.8.5, when Hybrid Auth is used, does not verify X.509 certificates from security gateways, which allows man-in-the-middle attackers to spoof security gateways and obtain sensitive information via a crafted certificate.

The weakness was published 09/18/2013 by Alexander Traud as APPLE-SA-2013-09-18-2 iOS 7 as confirmed mailinglist post (Website). The advisory is shared at prod.lists.apple.com. The mailinglist post contains:

The DNS name of an IPSec Hybrid Auth server was not being matched against the certificate, allowing an attacker with a certificate for any server to impersonate any other. This issue was addressed by improved certificate checking.
The identification of this vulnerability is CVE-2013-1028 since 01/10/2013. 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. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 05/25/2021). It is expected to see the exploit prices for this product increasing in the near future.

The vulnerability scanner Nessus provides a plugin with the ID 69877 (Mac OS X 10.8.x < 10.8.5 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 121456 (Apple Mountain Lion v10.8.5 and Security Update 2013-004 Not Installed (APPLE-SA-2013-09-12-1)).

Upgrading to version iOS 7.0 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (87116) and Tenable (69877). zdnet.com is providing further details. Similar entries are available at 5610, 8167, 8303 and 8792.
