VAR-201702-0117

Vulnerability from variot - Updated: 2025-04-20 23:42

The implementation of an ANSI X9.31 RNG in Fortinet FortiGate allows attackers to gain unauthorized read access to data handled by the device via IPSec/TLS decryption. Fortinet FortiOS is prone to an information-disclosure vulnerability. Attackers can exploit this issue to obtain sensitive information that may aid in further attacks. Fortinet FortiOS 4.3.0 through 4.3.18 are vulnerable. Fortinet FortiWLC is a wireless controller produced by Fortinet. A security vulnerability exists in the ANSI X9.31 RNG implementation in Fortinet FortiWLC
