Fortiguard released a security update for Forti Manager and Forti Analyzer to address an issue that provides a direct access to the root user which could lead to remote code of execution .

A Use After Free (CWE-416) vulnerability in FortiManager and FortiAnalyzer fgfmsd daemon may allow a remote, non-authenticated attacker to execute unauthorized code as root via sending a specifically crafted request to the fgfm port of the targeted device.

Products under Threat

  • FortiManager versions 5.6.10 and below.
  • FortiManager versions 6.0.10 and below.
  • FortiManager versions 6.2.7 and below.

1000D, 1000E, 2000E, 3000D, 3000E, 3000F, 3500E, 3500F, 3700F, 3900E.

To mitigate the issue permanently , Upgrade the existing version as described above to a higher version where this issue is sorted out for both FortiManager & FortiAnalyzer.
