Kerentanan Exposure of Sensitive Information to an Unauthorized Actor. Skor CVSS 3.1 3.1 (Low) menurut open-xchange.com.

Deskripsi (NVD)

The comparison used for the doveadm password and API key is not fully timing safe and can reveal the length of the configured secret. An attacker with access to the same network as the doveadm service, able to make repeated requests and measure response timing accurately, can learn the length of the secret, which reduces the effort needed to guess it. The secret value itself is not disclosed. Restrict network access to the doveadm service to trusted clients. Update to non-vulnerable version. No publicly available exploits are known.
