CVE-2022-26115Network attack vector

Password recovery via weak password hashing

Published Feb 16, 2023 · Updated Oct 22, 2024

Weak password hashing in Fortinet FortiSandbox 3.2.0 through 3.2.3 and 4.0.0 through 4.0.2 allows attackers to recover passwords. The password database stores hashes computed with insufficient work, making bulk guessing substantially more efficient. Exploitation requires access to the password database and exposes passwords recovered from its stored hashes.
