FortiAnalyzer: Weak Authentication
CVE-2024-50563 is a critical-severity weak authentication vulnerability in FortiAnalyzer from Fortinet, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected FortiAnalyzer versions: 7.6.0 through 7.6.1; 7.4.1 through 7.4.3. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.57% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Fortianalyzer Cloud to 7.4.4 or a later version.
- Update Fortimanager Cloud to 7.4.4 or a later version.
- Read the advisory on fortiguard.fortinet.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
