Fortinet Releases Advisory on New Post-Exploitation Technique for Known Vulnerabilities

https://www.cisa.gov/cybersecurity-advisories/alerts.xml / Fri, 04/11/2025 - 17:35

Fortinet is aware of a threat actor creating a malicious file from previously exploited Fortinet RCE vulnerabilities within FortiOS and FortiGate products. This malicious file could enable read-only access to files on the devices’ file system, which may include configurations. 

See the following resource for more information:

CISA encourages administrators to review Fortinet’s advisory and:

  • Upgrade to FortiOS versions 7.6.2, 7.4.7, 7.2.11, 7.0.17, 6.4.16 to remove the malicious file and prevent re-compromise.
  • Review the configuration of all in-scope devices.
  • Reset potentially exposed credentials.
  • As a work-around mitigation until the patch is applied, consider disabling SSL-VPN functionality, as exploitation of the file requires the SSL-VPN to be enabled.

Organizations should report incidents and anomalous activity to CISA’s 24/7 Operations Center at Report@cisa.gov or (888) 282-0870.
