Organizations should prioritize patching immediately. The updates addressing this issue are available in iOS 15.0.2, iPadOS 15.0.2, tvOS 15.1, watchOS 8.1, and macOS Monterey 12.0.1.
Vulnerability Details
The vulnerability is characterized as a logic issue, which has been addressed through improved restrictions. The specific CVE description states, 'A logic issue was addressed with improved restrictions. This issue is fixed in iOS 15.0.2 and iPadOS 15.0.2, tvOS 15.1, watchOS 8.1, macOS Monterey 12.0.1. A malicious application may be able to access information about a user's contacts.'
The CVSS score of 5.5 indicates a medium severity, with the attack vector classified as LOCAL. The attack complexity is low, meaning that an attacker may exploit this vulnerability with relative ease given the right conditions.
This vulnerability affects multiple components, including iOS, iPadOS, macOS, tvOS, and watchOS, indicating a broad potential impact across Apple's ecosystem.
Technical Analysis
The root cause of CVE-2021-30895 lies in a logic flaw within the affected Apple operating systems. This flaw allows malicious applications to bypass intended restrictions, leading to potential unauthorized access to sensitive user data, specifically contact information.
The attack vector is local, meaning that an attacker must have access to the device to exploit the vulnerability. The complexity of the attack is low, and it requires no special privileges, although user interaction is necessary. This means that a user must inadvertently run the malicious application for the exploit to be successful.
In terms of impact, the confidentiality of user data is at high risk, as the vulnerability could allow unauthorized access to contact information. However, there is no impact on integrity or availability.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant, particularly for organizations that rely on Apple devices for their operations. Given the high confidentiality impact, organizations face risks related to data exposure and potential breaches of privacy.
With a CVSS score of 5.5 and no known active exploits at this time, it is crucial for organizations to incorporate this vulnerability into their risk management strategies. The urgency of addressing this vulnerability is moderate, and it should be included in the priority patch cycle.
