CVE-2023-41974 is classified as a high-severity vulnerability due to its CVSS score of 7.8. This vulnerability allows an application to exploit a use-after-free condition, potentially leading to arbitrary code execution with kernel privileges. Specifically, the vulnerability arises from improper memory management, which has been addressed in iOS 17 and iPadOS 17, as well as in the updates for iOS 15.8.7 and iPadOS 15.8.7.
Risk to organizations includes unauthorized access and control over affected devices, significantly impacting confidentiality, integrity, and availability. Given that exploitation requires local access and user interaction, the threat still poses a serious risk, especially in environments where sensitive data is handled.
As of now, there are no confirmed public exploits for this vulnerability, but it is important to note that it has been included in the Known Exploited Vulnerabilities (KEV) catalog, indicating its critical nature and potential for exploitation. Organizations should prioritize patching immediately to mitigate risks.
The urgency for defenders is heightened due to the potential impact of this vulnerability. Organizations should ensure that their devices are updated to the latest versions to protect against possible exploitation.
Vulnerability Details
The official description of CVE-2023-41974 states that it is a use-after-free issue which was addressed with improved memory management. This vulnerability affects the Apple iOS and iPadOS platforms and is documented under CWE-416. The CVSS score of 7.8 indicates high severity, with impacts on confidentiality, integrity, and availability being rated as high as well.
Affected products include iOS and iPadOS versions prior to the fixed versions of 17 and 15.8.7. The vulnerability was published on January 10, 2024, and is classified as analyzed.
Technical Analysis
The root cause of CVE-2023-41974 is related to improper memory management leading to a use-after-free condition. This can occur when the application attempts to access memory that has already been freed, allowing for potential arbitrary code execution. The attack vector is local, meaning that an attacker would need physical access to the device. Attack complexity is low, and no privileges are required to exploit this vulnerability. However, user interaction is required to trigger the vulnerability.
In terms of impact, confidentiality, integrity, and availability could all be significantly compromised, allowing attackers to manipulate or access sensitive information on the device.
Risk & Impact Analysis
The impact of CVE-2023-41974 on organizations can be severe, especially in contexts where devices manage sensitive data. The ability to execute arbitrary code with kernel privileges means that an attacker could gain full control over an affected device, potentially leading to data breaches or unauthorized access to critical systems. Given that this vulnerability is classified as high severity, organizations should assess their exposure and take immediate action.
With the vulnerability included in the KEV catalog, it signifies a recognized threat that could be actively exploited in the wild. Organizations should prioritize patching affected systems to prevent potential exploitation.
The urgency for remediation is critical, given the potential for exploitation. Organizations must ensure timely updates and consider the broader implications of device security within their operational environment.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | Yes |
Ransomware Use | No |
Affected Versions
All versions prior to vendor patch are affected, specifically iOS versions up to 15.8.7 and iPadOS versions up to 15.8.7, as well as versions starting from 16.0 to below 17.0.
Mitigation & Remediation
Organizations should apply mitigations as per vendor instructions. To remediate, it is crucial to upgrade to iOS 17 or iPadOS 17, or to iOS 15.8.7 and iPadOS 15.8.7 if using earlier versions. For those unable to upgrade, consider implementing configuration hardening and network controls.
Monitoring for unusual application behavior can also aid in detecting potential exploitation attempts. For further assistance, organizations can refer to resources on penetration testing and security assessments.
Detection Guidance
Organizations should monitor logs for indicators of exploitation attempts, such as abnormal application crashes or system behavior. Behavioral anomalies in user operations, especially when accessing sensitive applications, should be flagged for review.
Additionally, establishing network signatures to detect potential exploit traffic can provide early warnings of attack attempts, enabling timely responses.
