Net-SNMP snmpd.conf tokens security bypass
| netsnmp-rocommunity-rouser-security-bypass (30782) |  Medium Risk |
Description:
Net-SNMP could allow a remote authenticated attacker to bypass security restrictions caused by improper handling of the rocommunity and rouser configuration directives in snmpd.conf. If Net-SNMP is configured to use rocommunity or rouser snmpd.conf tokens, a remote attacker could exploit this vulnerability to obtain write access to read-only resources.
