Listen to this Post

CVE-2025-24149 is a critical out-of-bounds read vulnerability affecting multiple Apple platforms, including iPadOS, macOS, visionOS, iOS, watchOS, and tvOS. This vulnerability arises due to improper bounds checking during file parsing, which can lead to unauthorized disclosure of user information. When a maliciously crafted file is processed, the system fails to validate the bounds of memory access, allowing an attacker to read data beyond the intended memory buffer. This could expose sensitive user data stored in memory, such as login credentials, personal files, or system information. Apple addressed this issue in updates like iPadOS 17.7.4, macOS Ventura 13.7.3, and iOS 18.3, among others. The CVSS 4.0 score reflects its critical severity, emphasizing the need for immediate patching to prevent exploitation.

DailyCVE Form:

Platform: Apple Devices
Version: iPadOS 17.7.4, macOS Ventura 13.7.3, iOS 18.3
Vulnerability: Out-of-Bounds Read
Severity: Critical
Date: 01/27/2025

What Undercode Say:

1. Exploitation Details:

  • Craft a malicious file to trigger out-of-bounds read.
  • Use tools like Hex editors to manipulate file headers.
  • Exploit memory leaks to extract sensitive data.

2. Protection Measures:

  • Update to latest Apple OS versions.
  • Disable automatic file parsing for untrusted sources.
  • Implement memory-safe programming practices.

3. Analytics:

  • Monitor memory access patterns for anomalies.
  • Use intrusion detection systems IDS to flag suspicious file processing.
  • Analyze logs for unexpected file access attempts.

4. Commands:

– `sudo softwareupdate –install –all` macOS update.
– `system_profiler SPSoftwareDataType` check OS version.
– `log show –predicate ‘eventMessage contains “file parsing”‘` monitor logs.

5. Code Snippets:

  • Bounds-checking example in C: 
    if index < buffer_size {
data = buffer[index];
} else {
return ERROR_OUT_OF_BOUNDS;
}

  • [Memory Safety Best Practices]https://owasp.org/www-community/vulnerabilities/Memory_leak

7. Tools:

  • Hex editors e.g., HxD, Hex Fiend.
  • IDA Pro for reverse engineering.
  • Valgrind for memory leak detection.

8. Additional Recommendations:

  • Regularly audit third-party libraries for vulnerabilities.
  • Use Address Space Layout Randomization ASLR to mitigate exploitation.
  • Educate users on avoiding untrusted file sources.
    By following these steps, users and developers can mitigate the risks associated with CVE-2025-24149 and protect sensitive data from unauthorized access.
