Vulnerability Details
The vulnerability is characterized as a memory corruption issue that could allow an application to execute arbitrary code with kernel privileges. Apple has fixed this issue in iOS 13.6, iPadOS 13.6, and tvOS 13.4.8. The vulnerability has a CVSS score of 7.8 based on the NVD metrics, indicating high severity.
The attack vector for this vulnerability is local, requiring user interaction, and it has low attack complexity. The required privileges for exploitation are none, making it accessible to any user of the affected device. The impacts on confidentiality, integrity, and availability are all rated high, indicating a significant potential for damage.
The affected products include iOS, iPadOS, and tvOS, with specific configurations being vulnerable up to certain versions. The CWE classification for this vulnerability is CWE-787, which pertains to improper access control.
Technical Analysis
The root cause of CVE-2020-9907 lies in a memory corruption issue that results from improper handling of memory operations. This flaw allows attackers to manipulate memory in a way that can lead to arbitrary code execution. The attack vector is local, meaning that an attacker would need physical access to the device to exploit this vulnerability. User interaction is required, as the victim would need to open a malicious application to trigger the vulnerability.
The attack complexity is low, which means that an attacker could exploit this vulnerability without significant effort. There are no specific privilege requirements, making it accessible to any user of the device. The impacts of a successful exploitation are severe, with high risks to confidentiality, integrity, and availability of the system.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access and control over devices running affected versions of Apple operating systems. The vulnerability's ability to execute arbitrary code with kernel privileges can lead to significant security breaches, including data theft and loss of system integrity. Given its local attack vector and user interaction requirement, the immediate risk is higher for environments where users are more likely to install untrusted applications.
The urgency for organizations to address this vulnerability is critical due to its high CVSS score and the nature of the exploit. Organizations should implement immediate remediation strategies to prevent potential exploitation, including applying the necessary patches provided by Apple.
