CVE-2021-32596

Password disclosure via predictable-salt hashing

Published Aug 4, 2021 · Updated Oct 25, 2024

Password-hashing weakness in Fortinet FortiPortal 6.0.0 through 6.0.4 allows local users to recover stored passwords. The password store applies a one-way digest with a predictable salt, enabling password recovery through precomputed tables. Exploitation requires high-privilege local access and prior possession of the password store; the resulting impact is password disclosure only.
