Vulnerability Overview

CVE-2024-23113 is a format string vulnerability in the Fortinet FortiOS fgfmd daemon. The fgfmd daemon handles FortiGate-to-FortiManager communication, and a format string flaw in its request parsing allows remote unauthenticated attackers to execute arbitrary code.

Impact Assessment

Exploitation of this vulnerability allows complete device takeover. Attackers can gain root-level access to FortiGate devices, intercept network traffic, modify firewall rules, and pivot into protected network segments.

Affected Products

FortiOS 7.0 (all versions before 7.0.14), FortiOS 7.2 (all versions before 7.2.7), FortiOS 7.4 (all versions before 7.4.3). FortiProxy and FortiPAM are also affected.

Recommended Actions

  • Update to FortiOS 7.0.14, 7.2.7, or 7.4.3 immediately.
  • As a workaround, disable fgfmd access on all interfaces.
  • Monitor for indicators of compromise.
  • Review CISA KEV catalog for compliance deadlines.
