CVE-2019-7287 is a high-severity vulnerability identified in Apple iOS. This vulnerability allows an application to execute arbitrary code with kernel privileges due to a memory corruption issue that has been addressed with improved input validation. The issue is fixed in iOS version 12.1.4. Organizations using affected versions should take immediate action to mitigate potential risks.
The CVSS score for this vulnerability is 7.8, indicating a high severity level that necessitates prompt attention. The attack vector is local, meaning an attacker needs physical access to the device to exploit the vulnerability. With a low attack complexity and no privileges required, the risk to organizations includes potential unauthorized access to sensitive data and system integrity.
As of now, there is no known exploit for this vulnerability, but it has been added to the Known Exploited Vulnerabilities (KEV) catalog, indicating its significance in terms of risk. Organizations should prioritize patching immediately to protect against potential exploitation.
The urgency for defenders is critical. With the increasing number of attacks targeting mobile devices, it is essential to address this vulnerability as part of a comprehensive security strategy.
Vulnerability Details
The vulnerability description states, "A memory corruption issue was addressed with improved input validation. This issue is fixed in iOS 12.1.4. An application may be able to execute arbitrary code with kernel privileges." It falls under the Common Weakness Enumeration (CWE) category of CWE-787.
The CVSS 3.1 vector string is CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, which indicates a high impact on confidentiality, integrity, and availability. The attack vector is local, requiring user interaction, which adds a layer of complexity to exploitation.
This vulnerability affects all versions of iOS prior to 12.1.4, and organizations should ensure they are running the latest version to mitigate risks.
Technical Analysis
The root cause of CVE-2019-7287 is a memory corruption issue, which occurs when the system does not properly handle certain inputs, leading to unpredictable behavior and potential execution of arbitrary code. The attack complexity is low, and no privileges are required for exploitation, making it a significant threat.
User interaction is required, which means that an attacker would need to convince a user to execute a malicious application or open a compromised file. The impact on confidentiality, integrity, and availability is high, as successful exploitation can lead to complete system compromise.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2019-7287 is significant, particularly for organizations that rely on iOS devices for critical operations. If exploited, attackers could gain kernel-level access to devices, allowing them to modify system files, access sensitive data, or deploy additional malicious payloads.
Given the high CVSS score and the fact that it is included in the KEV catalog, organizations should prioritize remediation efforts. The blast radius for this vulnerability is considerable, as it affects all devices running the vulnerable iOS versions.
