My Security Team has pointed out a point regarding SNMP v3 communication.
There could be a security problem. It could be possible to bypass the authentication function.
SNMPv3 use Hash Message Authentication Code (HMAC), described in RFC3414 and this use HMAC-MD5-96 or HMAC-SHA-96.
The Problem could be that a System send out a one Byte HMAC to authenticate successful.
Is this security issue with prognosis? Or how was this problem resolved?
