CVE-2021-32591Network attack vector

Credential disclosure via incomplete password encryption

Published Dec 8, 2021 · Updated Oct 25, 2024

Missing cryptographic steps in Fortinet FortiSandbox before 4.0.1 allow attackers with the password store to recover LDAP and RADIUS secrets. The credential-encryption function omits undisclosed cryptographic operations, leaving stored LDAP and RADIUS passwords insufficiently protected. Exploitation requires possession of the password store and is limited to disclosure of the encrypted credentials.
