AI-suggested
Upgrade Catalyst::Plugin::Authentication to version 0.10029 or later, which addresses this timing attack vulnerability by fixing the legacy verifier. Avoid using the deprecated legacy login method and switch to the realm-based verifier that has been fixed. No other mitigation is indicated.
Description
Catalyst::Plugin::Authentication versions before 0.10029 for Perl contain a timing attack vulnerability in the legacy password verifier. The legacy verifier uses eq comparisons for clear-text passwords, crypt hashes, and base64 digests, causing comparison time to vary based on matching leading bytes. This allows a remote attacker to infer stored passwords or hashes by measuring response times. The issue was fixed in the realm-based verifier but remains in the deprecated legacy verifier.
