Recently an unauthenticated arbitrary file read vulnerability was discovered in Fortinet VPN service. The vulnerability allows an unauthenticated remote attacker to send a specially crafted request in order to read an arbitrary file from the vulnerable server file system. The vulnerability affects the following FortiOS versions:

  • 5.6.3 to 5.6.7
  • 6.0.0 to 6.0.4


Exploits targeting this vulnerability were posted online a few days ago and researchers at F5 Networks have already detected threat campaigns targeting this vulnerability.


Mitigation with BIG-IP ASM

ASM customers under any supported BIG-IP version are already protected against this vulnerability as the exploitation attempt will be detected by existing “Path traversal” signatures.
