CVE-2022-32797 is a high-severity vulnerability affecting Apple macOS systems. This vulnerability allows processing a maliciously crafted AppleScript binary, which may result in unexpected termination or disclosure of process memory. The CVSS score for this vulnerability is 7.1, indicating a high level of risk for organizations.
Organizations using the affected macOS versions should take this vulnerability seriously, as it poses a risk to the confidentiality and availability of process memory. The attack vector is local, meaning an attacker would need legitimate access to the system, which may still be exploitable in environments with less strict security controls.
The vulnerability was published on September 23, 2022, and has been classified under CWE-20, indicating improper input validation. Due to its nature, organizations should prioritize patching immediately to mitigate risks associated with this vulnerability.
There are currently no known exploits in the wild for this vulnerability; however, the potential impact on organizations remains significant. Implementing the latest security updates is critical to ensure systems are protected.
Vulnerability Details
The official description for CVE-2022-32797 states: 'This issue was addressed with improved checks. This issue is fixed in Security Update 2022-005 Catalina, macOS Big Sur 11.6.8, macOS Monterey 12.5.' The vulnerability type is classified as a high-severity issue that requires user interaction for exploitation.
The attack complexity is rated as low, meaning that an attacker may successfully exploit this vulnerability with minimal effort. Privileges are not required, and user interaction is necessary, which means a user must execute the malicious AppleScript.
The confidentiality impact is high, meaning that sensitive information may be disclosed as a result of the vulnerability. The integrity impact is none, and the availability impact is high, indicating that the vulnerability could lead to unexpected termination of processes.
Technical Analysis
The root cause of CVE-2022-32797 lies in inadequate validation of AppleScript binaries. When a malicious AppleScript is processed, it can lead to unexpected termination of the application and may expose sensitive process memory to unauthorized access.
The attack vector is local, meaning an attacker must have physical access to the machine or have credentials that allow script execution. While the vulnerability requires user interaction, it could be exploited in instances where users are tricked into executing malicious scripts.
Given the low attack complexity and lack of required privileges, the vulnerability can be leveraged by threat actors with limited technical skills. The potential for high confidentiality and availability impacts makes this vulnerability a serious concern for organizations.
Risk & Impact Analysis
Risk to organizations includes potential exposure of sensitive information and disruption of service due to unexpected application termination. The blast radius of this vulnerability is significant, particularly in environments where AppleScript is frequently utilized and user interaction is a common practice.
Organizations should evaluate their security posture and implement immediate patches to mitigate risks associated with CVE-2022-32797. Given the exploitation potential, this vulnerability should be addressed in the priority patch cycle.
