CVE-2024-42165Public exploitNetwork attack vector

Account activation via predictable security tokens

Published Aug 12, 2024 · Updated Aug 12, 2024

Insufficiently random activation tokens in FIWARE Keyrock 8.4 and earlier allow remote authenticated users to activate any new account. The activation-token generator derives security tokens from predictable Math.random() output, while the /activate route accepts a predicted token without authentication. A non-admin account must first request multiple password-reset tokens to recover the generator state; successful prediction changes an unactivated account to active.
