Apple, File Parsing Vulnerability, CVE-2025-24124 (Critical)

By /

How the Mentioned CVE Works:

CVE-2025-24124 is a critical vulnerability affecting multiple Apple platforms, including iOS, iPadOS, macOS, visionOS, watchOS, and tvOS. The issue arises due to improper file parsing mechanisms, which can cause an application to terminate unexpectedly when processing a maliciously crafted file. This vulnerability is rooted in insufficient validation checks during file parsing, allowing an attacker to exploit the flaw by sending a specially designed file to the target device. When the file is parsed, it triggers a memory corruption or buffer overflow, leading to a crash or potential arbitrary code execution. Apple addressed this issue in updates such as iPadOS 17.7.4, macOS Ventura 13.7.3, and iOS 18.3 by implementing improved validation checks.

What Undercode Say:

1. Exploitation Details:

  • Craft a malicious file with malformed headers or oversized payloads.
  • Send the file via email, messaging apps, or file-sharing platforms.
  • Trigger parsing by opening the file on the target device.

2. Protection Measures:

  • Update devices to the latest OS versions: iPadOS 17.7.4, macOS Ventura 13.7.3, iOS 18.3.
  • Disable automatic file parsing in untrusted applications.
  • Use endpoint protection tools to detect malicious files.

3. Analytics:

  • CVSS Score: 9.8 (Critical)
  • Attack Vector: Network
  • Attack Complexity: Low
  • User Interaction Required: Yes

4. Commands:

  • Check macOS version: `sw_vers`
    – Verify iOS version: Go to Settings > General > About.
  • Force update: `softwareupdate –install –all`

5. Code Snippets:

  • Detect vulnerable versions in Python: 
    import platform
os_version = platform.mac_ver()[0]
if os_version < "13.7.3":
print("Vulnerable to CVE-2025-24124")

6. URLs:

7. Additional Tools:

  • Use Wireshark to analyze network traffic for malicious file transfers.
  • Deploy Snort IDS to detect exploit attempts.

8. Mitigation Script:

Disable automatic file previews in macOS
defaults write com.apple.finder QLEnableXRayFolders -bool false
killall Finder

9. References:

10. Remediation Steps:

  • Educate users on avoiding untrusted file sources.
  • Regularly monitor for new patches and updates.
  • Conduct penetration testing to identify vulnerable systems.
    By following these steps, organizations can mitigate the risks associated with CVE-2025-24124 and protect their Apple devices from exploitation.
