How to Fix CVE-2023-27580

To remediate this vulnerability, upgrade all affected Codeigniter4/shield dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

codeigniter4/shield fixed: 1.0.0-beta.4
Upgrade codeigniter4/shield to 1.0.0-beta.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for codeigniter4/shield

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-27580, inspect your project dependencies for Codeigniter4/shield:

inspect dependencies for codeigniter4/shield

Analyze the terminal output to locate any version of Codeigniter4/shield in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.0-beta.4), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-916: Use of Password Hash With Insufficient Computational Effort, where the product generates a hash for a password, but it uses a scheme that does not provide a sufficient level of computational effort that would make password cracking attacks infeasible or expensive. 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 An improper implementation was found in the password storage process. All hashed passwords stored in Shield v1.0.0-beta.3 or earlier are easier to crack than expected due to the vulnerability. Therefore, they should be removed as soon as possible. If an attacker gets (1) the user's hashed password by Shield, and (2) the hashed password (SHA-384 hash without salt) from somewhere, the attacker may easily crack the user's password. ### Patches Upgrade to Shield v1.0.0-beta.4 or later. After upgrading, all users’ hashed passwords should be updated (saved to the database). See https://github.com/codeigniter4/shield/blob/develop/UPGRADING.md for details. ### Workarounds None. ### References - https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html#pre-hashing-passwords - https://blog.ircmaxell.com/2015/03/security-issue-combining-bcrypt-with.html - https://www.scottbrady91.com/authentication/beware-of-password-shucking ### 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)
