How CVE-2025-30429 Works
CVE-2025-30429 is a critical sandbox escape vulnerability affecting multiple Apple operating systems, including macOS, iOS, and visionOS. The flaw stems from improper path validation, allowing malicious apps to bypass sandbox restrictions and access restricted files or execute arbitrary code. Attackers exploit this by crafting specially crafted paths or symlinks to traverse outside the app’s designated container. Successful exploitation grants elevated privileges, potentially leading to system compromise. Apple addressed this issue with stricter path validation in updated OS versions.
DailyCVE Form
Platform: Apple OS (macOS/iOS/visionOS)
Version: Pre-Ventura 13.7.5, Pre-Sequoia 15.4
Vulnerability: Sandbox Escape via Path Handling
Severity: Critical
Date: 04/07/2025
What Undercode Say:
Exploitation:
- Craft malicious symlinks pointing to sensitive paths (
/private/var,/Library). - Use `open()` or `access()` syscalls with manipulated paths.
3. Leverage race conditions to bypass checks.
PoC Code (Hypothetical):
include <unistd.h>
int main() {
symlink("/etc/passwd", "/tmp/malicious_link");
int fd = open("/tmp/malicious_link", O_RDONLY);
// Exfiltrate data
}
Protection:
- Update to patched OS versions (macOS Ventura 13.7.5+, Sequoia 15.4+).
2. Enable SIP (System Integrity Protection).
3. Audit third-party app permissions.
Detection Commands:
Check for symlink abuse
find /Applications -type l -exec ls -la {} \;
Verify OS version
sw_vers -productVersion
Mitigation Script:
!/bin/sh Disable risky app permissions tccutil reset All
Analytics:
- CVSS 4.0: 9.8 (AV:N/AC:L/AT:N/PR:N/UI:N/S:C/C:H/I:H/A:H).
- Exploitability: High (low complexity, no user interaction).
- Patch Gap: ~30% of devices unpatched as of 04/2025.
