CVE-2024-27853: A maliciously crafted ZIP archive may bypass Gatekeeper checks in Apple macOS
CVE-2024-27853 is a medium severity vulnerability in Apple macOS Sonoma where a maliciously crafted ZIP archive may bypass Gatekeeper checks. Gatekeeper is a security feature designed to ensure that only trusted software runs on macOS. This issue was addressed with improved checks in macOS Sonoma 14. 4, released on March 7, 2024. The vulnerability allows a crafted ZIP file to circumvent these security checks, potentially enabling untrusted code to run. The CVSS score is 4. 4, indicating a low to medium impact with limited confidentiality and integrity effects and no availability impact. No known exploits are reported in the wild. Apple has provided an official fix in macOS Sonoma 14. 4.
AI Analysis
Technical Summary
This vulnerability involves a logic flaw in the libarchive component of macOS Sonoma that allowed a maliciously crafted ZIP archive to bypass Gatekeeper security checks. Gatekeeper is intended to prevent untrusted or malicious software from executing by verifying the integrity and source of application bundles. The issue was resolved by Apple through improved validation and checks in macOS Sonoma 14.4. The CVSS vector indicates the attack requires local access with low complexity, no privileges, and user interaction, affecting confidentiality and integrity to a limited extent without impacting availability.
Potential Impact
If exploited, this vulnerability could allow a malicious ZIP archive to bypass Gatekeeper protections, potentially enabling execution of untrusted or malicious code on the affected system. The impact is limited to confidentiality and integrity with no direct availability impact. There are no reports of active exploitation in the wild. The vulnerability requires local access and user interaction to trigger.
Mitigation Recommendations
Apple has released an official fix for this vulnerability in macOS Sonoma 14.4. Users and administrators should update affected systems to macOS Sonoma 14.4 or later to remediate this issue. No additional mitigation steps are required beyond applying the official update.
