## Summary

This vulnerability affects Fortinet's FortiOS operating system, the software that runs FortiGate firewalls. An attacker who obtains a configuration backup file could decrypt sensitive information stored in it, including user passwords, private key passphrases, and the High Availability password when one is set.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Fortinet FortiGate: 5.6.9 and below, 6.0.5 and below, 6.2.0

## Description

Use of a hard-coded cryptographic key to cipher sensitive data in FortiOS configuration backup file may allow an attacker with access to the backup file to decipher the sensitive data, via knowledge of the hard-coded key. The aforementioned sensitive data includes users' passwords (except the administrator's password), private keys' passphrases and High Availability password (when set).
