CVE-2024-23205 is a privacy vulnerability identified in Apple iOS and iPadOS, where an application may gain unauthorized access to sensitive user data through insufficient redaction of private information in system log entries. The root cause is related to CWE-922, which involves improper data redaction or sanitization, allowing sensitive data to be exposed inadvertently. The vulnerability affects unspecified versions prior to the patched releases and was addressed by Apple in iOS 17.4, iPadOS 17.4, and macOS Sonoma 14.4. The CVSS v3.1 base score is 5.5 (medium), with an attack vector of local (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high confidentiality impact (C:H), but no impact on integrity or availability. This means an attacker with local privileges on the device, such as a malicious app granted some level of access, could extract sensitive data from logs that were previously not properly redacted. The vulnerability does not require user interaction, increasing the risk if a malicious app is installed. No known exploits have been reported in the wild, but the potential for privacy breaches exists if devices remain unpatched. The issue highlights the importance of secure logging practices and strict data redaction to prevent leakage of sensitive information through diagnostic or system logs.

For European organizations, this vulnerability poses a privacy risk primarily to users of Apple mobile devices running affected iOS and iPadOS versions. Sensitive user data exposure could lead to leakage of personal or corporate information, potentially violating GDPR and other privacy regulations. The impact is mainly on confidentiality, with no direct effect on system integrity or availability. Organizations relying on Apple devices for communication, remote work, or mobile applications may face increased risk if malicious apps exploit this flaw to harvest sensitive data. Although exploitation requires local privileges, the widespread use of mobile apps and potential for privilege escalation means attackers could leverage this vulnerability as part of a broader attack chain. The absence of known exploits reduces immediate risk, but delayed patching could expose organizations to privacy breaches and regulatory penalties. The vulnerability underscores the need for strict control over app permissions and timely OS updates to maintain data privacy compliance.

1. Immediately update all Apple devices to iOS 17.4, iPadOS 17.4, or macOS Sonoma 14.4 or later to apply the patch that fixes the vulnerability. 2. Enforce strict app vetting and permission policies to limit the installation of untrusted or unnecessary apps that could exploit local privileges. 3. Use Mobile Device Management (MDM) solutions to monitor device compliance and enforce OS update policies across the organization. 4. Restrict local user privileges on devices where possible to minimize the risk of privilege escalation and unauthorized access to logs. 5. Educate users about the risks of installing apps from unverified sources and encourage adherence to corporate security policies. 6. Monitor device logs and behavior for unusual access patterns that could indicate attempts to exploit this vulnerability. 7. Review and harden logging configurations where feasible to ensure sensitive data is not unnecessarily logged or accessible. 8. Coordinate with legal and compliance teams to ensure privacy impact assessments and incident response plans account for potential data exposure scenarios related to this vulnerability.
