A vulnerability has been reported in FreeRADIUS, which can be exploited by malicious people to cause a DoS (Denial of Service) and to bypass certain security restrictions.
The vulnerability is caused due to an input validation error in the EAP-MSCHAPv2 state machine. This can be exploited by manipulating the EAP-MSCHAPv2 state machine on a client system to bypass server authentication checks.
Successful exploitation may allow the attacker to gain network access without requiring knowledge of logon credentials or cause the server to crash.
The vulnerability has been reported in version 1.0.0 through 1.1.0.
