Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-312: Cleartext Storage of Sensitive Information, where the product stores sensitive information in cleartext within a resource that might be accessible to another control sphere. In Codeigniter4/shield, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact **secretKey**, an important key for HMAC SHA256 authentication, was stored in the database in raw form. If a malicious person somehow had access to the data in the database, they could use the key and secretKey for HMAC SHA256 authentication to send requests impersonating that person. ### Patches Upgrade to Shield v1.0.0-beta.8 or later. After upgrading, all existing secret keys must be encrypted. See https://github.com/codeigniter4/shield/blob/develop/UPGRADING.md for details. ### Workarounds None. ### References - https://codeigniter4.github.io/shield/references/authentication/hmac/ ### For more information If you have any questions or comments about this advisory: * Open an issue or discussion in [codeigniter4/shield](https://github.com/codeigniter4/shield) * Email us at [security@codeigniter.com](mailto:security@codeigniter.com)
