CVE-2014-4499 in Mac OS X
Summary
by MITRE
The App Store process in CommerceKit Framework in Apple OS X before 10.10.2 places Apple ID credentials in App Store logs, which allows local users to obtain sensitive information by reading a file.

The vulnerability described in CVE-2014-4499 represents a critical security flaw in Apple's operating system that affects versions prior to 10.10.2. This issue resides within the CommerceKit Framework's App Store process, which is responsible for handling application purchases and related transactions within the macOS environment. The flaw manifests as an improper logging mechanism that inadvertently captures and stores sensitive authentication credentials in plain text within log files, creating a significant exposure point for unauthorized access.
The technical implementation of this vulnerability stems from the CommerceKit Framework's design decision to include Apple ID credentials in its logging infrastructure without proper sanitization or encryption measures. When users interact with the App Store application, the framework generates log entries that contain authentication information, including usernames and potentially password hashes or tokens. These log entries are stored in accessible file locations within the operating system, where they remain visible to any local user with appropriate permissions. The flaw specifically impacts the App Store process execution context, making it particularly dangerous as it operates with elevated privileges and has access to sensitive user data.
The operational impact of this vulnerability extends beyond simple credential exposure, as it provides attackers with persistent access to user accounts and their associated privileges. Local users who gain access to these log files can extract Apple ID credentials and use them to authenticate to Apple services, potentially gaining access to purchased applications, personal data, and financial information. The vulnerability operates at the system level and affects all users of affected macOS versions, creating a widespread risk that could be exploited by both malicious insiders and external attackers who gain local access to compromised systems. This represents a significant violation of the principle of least privilege and demonstrates poor secure coding practices in the handling of sensitive information.
From a cybersecurity framework perspective, this vulnerability aligns with CWE-312 (Cleartext Storage of Sensitive Information) and represents a clear violation of the principle of defense in depth. The flaw also corresponds to techniques described in the MITRE ATT&CK framework under T1003 (Credential Dumping) and T1070 (Indicator Removal on Host), as it creates persistent credential storage that attackers can leverage for further exploitation. Organizations and users affected by this vulnerability should immediately update to macOS 10.10.2 or later, which addresses the logging mechanism to properly sanitize credential information before storage. Additional mitigations include implementing strict access controls on system log directories, monitoring for unauthorized file access, and conducting regular security audits to identify other potential credential exposure points. The vulnerability underscores the critical importance of secure logging practices and proper credential handling in system frameworks, particularly those dealing with user authentication and financial transactions.
