MicroTik Router <= 2.9.51 / 3.13 SNMP Request Read-only Restriction Bypass
High Nessus Network Monitor Plugin ID 4643
SynopsisThe remote host is vulnerable to a flaw that allows for the bypassing of authentication.
DescriptionThe remote host is running a MicroTik router.
This version of MicroTik router is vulnerable to a flaw within its SNMP module. An attacker exploiting this vulnerability would send the MicroTik router malformed SNMP queries. These queries would bypass any local 'read-only' restrictions and be executed by the router.
SolutionIf possible, disable SNMP or only allow queries from trusted hosts. When available, upgrade to a version higher than 2.9.51 or 3.13.
