CVE-2022-32787 is a high-severity vulnerability affecting multiple Apple products, including iOS, iPadOS, macOS, tvOS, and watchOS. The vulnerability arises from an out-of-bounds write issue that could lead to arbitrary code execution when processing maliciously crafted web content. Given the nature of this vulnerability, it poses a significant risk to users who have not updated their systems.
This vulnerability has an assigned CVSS score of 8.8, indicating a high level of severity. It is classified as a network attack vector with low complexity and does not require any privileges or user interaction to exploit. The urgency for organizations to address this vulnerability is critical, as it could lead to unauthorized access and control over affected systems.
Organizations should prioritize patching immediately. The issue has been resolved in the following versions: iOS 15.6, iPadOS 15.6, macOS Big Sur 11.6.8, watchOS 8.7, tvOS 15.6, and macOS Monterey 12.5, along with Security Update 2022-005 for Catalina. Failure to update could expose users to significant security risks.
The CVE was published on September 23, 2022, and is classified under CWE-787, indicating an out-of-bounds write vulnerability. As the last modified date was in May 2025, it is important for users to remain vigilant regarding updates and security patches.
Vulnerability Details
The official description of the vulnerability states that it allows for arbitrary code execution due to an out-of-bounds write issue. The vulnerability's CVSS score of 8.8 categorizes it as high severity, with significant impacts on confidentiality, integrity, and availability.
Affected products include iOS, iPadOS, macOS Big Sur, watchOS, tvOS, and macOS Monterey. The vulnerability was addressed in the respective updates listed above.
Technical Analysis
The root cause of CVE-2022-32787 stems from inadequate bounds checking, which allows attackers to write outside the allocated memory buffers. This can lead to arbitrary code execution under specific conditions.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely. The complexity of the attack is low, requiring no special privileges, but does necessitate user interaction to trigger the vulnerability.
The impacts include high confidentiality, integrity, and availability risks, as successful exploitation can lead to unauthorized access and manipulation of sensitive data.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant, as it could potentially allow an attacker to gain full control over affected devices. Organizations must assess the blast radius, considering the number of devices that could be affected due to this vulnerability.
Given the CVSS score of 8.8 and the absence of known exploits, the urgency for remediation remains high. Organizations should schedule immediate updates to affected systems to mitigate any potential risks.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
