High Nessus Plugin ID 21678
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionThe freeradius development team reports :
A validation issue exists with the EAP-MSCHAPv2 module in all versions from 1.0.0 (where the module first appeared) to 1.1.0. Insufficient input validation was being done in the EAP-MSCHAPv2 state machine. A malicious attacker could manipulate their EAP-MSCHAPv2 client state machine to potentially convince the server to bypass authentication checks. This bypassing could also result in the server crashing
