CVE-2021-26098

Name of the Vulnerable Software and Affected Versions FortiSandbox versions prior to 4.0.0

Description An instance of small space of random values in the RPC API may allow an attacker in possession of a few information pieces about the state of the device to possibly predict valid session IDs.
