The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.29% chance of exploitation within 30 days, higher than 71% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Forticlient Enterprise Management Server to 7.0.13 or 7.2.5, whichever matches your release line, or a later version.
  2. Read the advisory on fortiguard.fortinet.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

An improper neutralization of special elements used in a command ('Command Injection') vulnerability [CWE-77] in Fortinet FortiClientEMS 7.2.0 through 7.2.4, 7.0.0 through 7.0.12 may allow an unauthenticated attacker to execute limited and temporary operations on the underlying database via crafted requests.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Improper Neutralization of Special Elements used in a Command

The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • If possible, ensure that all external commands called from the program are statically created.
  • Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
