This signature detects attempts to circumvent authentication in SNMPv3. Attackers sending large volumes of crafted SNMP packets may be able to read and/or write to SNMP MIB targets. A successful attack can result in information disclosure or system compromise.
Net-SNMP is prone to a remote authentication-bypass vulnerability caused by a design error. Successfully exploiting this issue will allow attackers to gain unauthorized access to the affected application. Net-SNMP 5.4.1, 5.3.2, 5.2.4, and prior versions are vulnerable.
