FortiManager: Use of Hard-coded Cryptographic Key
CVE-2024-33504 is a high-severity use of hard-coded cryptographic key vulnerability in FortiManager from Fortinet, with a CVSS 3.1 base score of 7.7 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected FortiManager versions: 7.6.0 through 7.6.1; 7.4.0 through 7.4.5; 7.2.0 through 7.2.9, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.3% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Fortimanager Cloud to 7.2.9 or 7.4.6, whichever matches your release line, or a later version.
- Read the advisory on fortiguard.fortinet.com for workarounds and exact fixed builds.
