CVE-2024-27821
CVE-2024-27821 is a path handling vulnerability affecting Apple devices. This flaw, now patched in iOS 17.5, iPadOS 17.5, watchOS 10.5, and macOS Sonoma 14.5, could allow a shortcut to expose sensitive user data without proper consent. While its CVSS score is 7.5, SOCRadar's Vulnerability Risk Score (SVRS) is 30, suggesting a lower immediate risk than the CVSS score would indicate, though still needing monitoring. However, the "In The Wild" and "Exploit Available" tags indicate active exploitation attempts, raising the potential threat level. This means attackers are actively trying to use this vulnerability. Users should update their Apple devices immediately to prevent unauthorized data leakage. While the SVRS is not critical (above 80), the presence of active exploits makes patching a priority.
Description
CVE-2024-27821 is a vulnerability in Apple's iOS, iPadOS, watchOS, and macOS operating systems. It stems from a path handling issue that allows a malicious shortcut to potentially leak sensitive user data without their consent.
While the CVSS score is 7.5, highlighting the vulnerability's severity, the SOCRadar Vulnerability Risk Score (SVRS) is significantly lower at 38. This suggests that while the vulnerability is exploitable, its immediate threat level might be lower compared to other vulnerabilities with higher SVRS scores.
Key Insights
- Path Handling Issue: The vulnerability arises from a flaw in how the operating system handles file paths. A malicious shortcut can potentially exploit this flaw to access and disclose sensitive user data.
- Data Leakage: The vulnerability allows a shortcut to leak sensitive user data without the user's knowledge or consent. This data could include personal information, financial details, or other sensitive data stored on the device.
- Active Exploitation: The vulnerability is being actively exploited by hackers in the wild. Exploits have been published and are available, making it easier for attackers to compromise devices.
- CISA Warning: The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning regarding this vulnerability, urging users to take immediate steps to mitigate the risk.
Mitigation Strategies
- Update Operating Systems: Immediately update to the latest versions of iOS, iPadOS, watchOS, and macOS. These updates include the necessary patches to address the vulnerability.
- Review and Delete Suspicious Shortcuts: Users should carefully review their shortcuts and delete any that appear suspicious or come from unknown sources.
- Disable Shortcuts Feature: As a precautionary measure, consider disabling the Shortcuts feature entirely until the vulnerability is fully addressed.
- Use Strong Passwords: Implement strong passwords for all accounts and consider enabling two-factor authentication for added security.
