Description

A missing cryptographic steps vulnerability in the function that encrypts users' LDAP and RADIUS credentials in FortiSandbox before 4.0.1, FortiWeb before 6.3.12, FortiADC before 6.2.1, FortiMail 7.0.1 and earlier may allow an attacker in possession of the password store to compromise the confidentiality of the encrypted secrets.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

5.0.0 ≤ v ≤ 5.4.46.0.0 ≤ v ≤ 6.0.36.1.0 ≤ v ≤ 6.1.36.2.06.2.1
5.0 ≤ v ≤ 5.6.36.0.0 ≤ v ≤ 6.0.116.2.0 ≤ v ≤ 6.2.76.4.0 ≤ v ≤ 6.4.57.0.07.0.1
v < 4.0.13.2.0 ≤ v ≤ 3.2.24.0.0
Affected range stops below 4.0.1, so it looks safe — our inference, not a vendor statement
5.7.0 ≤ v ≤ 5.7.35.8.0 ≤ v ≤ 5.8.76.0.0 ≤ v ≤ 6.0.76.1.0 ≤ v ≤ 6.1.26.2.0 ≤ v ≤ 6.2.46.3.0 ≤ v ≤ 6.3.115.9.05.9.1
