Fortinet FortiClient EMS

CVE-2023-48788

Fortinet FortiClient EMS contains a SQL injection vulnerability that allows an unauthenticated attacker to execute commands as SYSTEM via specifically crafted requests.

What this means for your business

  • It affects Fortinet FortiClient EMS. It matters if your company, or a supplier that handles your data, runs it.
  • Attackers are already using it. CISA added it to its list of flaws used in real attacks on 25 March 2024.
  • Ransomware gangs are known to have used it.
  • FIRST's prediction model gives it a 98% chance of attack attempts being seen in the next 30 days, ranking above 99% of all known flaws.

What to do

  1. 1Check whether your company or your suppliers run Fortinet FortiClient EMS.
  2. 2If you do, follow CISA's required action below. No patch reference has been published yet.
  3. 3Treat it as urgent. US federal agencies must fix it by 15 April 2024. That deadline does not apply to private companies, but it shows how seriously CISA takes it.
  4. 4Because attackers have used it, check the affected systems for signs of a break-in, not only for the update.
