An attacker could exploit this vulnerability by attempting to perform an SNMP operation using broadcast as the destination address that could be processed by an affected device that is configured with an SNMP server. A successful exploit could allow the attacker to communicate to the device on the configured SNMP ports. Although an unauthenticated attacker could send UDP datagrams to the configured SNMP port, only an authenticated user can retrieve or modify data using SNMP requests.", "affected": [ { "vendor": "Cisco", "product": "Cisco IOS XR Software", "versions": [ { "version": "5.2.0", "status": "affected" }, { "version": "5.2.1", "status": "affected" }, { "version": "5.2.2", "status": "affected" }, { "version": "5.2.4", "status": "affected" }, { "version": "5.2.3", "status": "affected" }, { "version": "5.2.5", "status": "affected" }, { "version": "5.2.47", "status": "affected" }, { "version": "5.3.0", "status": "affected" }, { "version": "5.3.1", "status": "affected" }, { "version": "5.3.2", "status": "affected" }, { "version": "5.3.3", "status": "affected" }, { "version": "5.3.4", "status": "affected" }, { "version": "6.0.0", "status": "affected" }, { "version": "6.0.1", "status": "affected" }, { "version": "6.0.2", "status": "affected" }, { "version": "6.1.1", "status": "affected" }, { "version": "6.1.2", "status": "affected" }, { "version": "6.1.3", "status": "affected" }, { "version": "6.1.4", "status": "affected" }, { "version": "6.1.12", "status": "affected" }, { "version": "6.1.22", "status": "affected" }, { "version": "6.1.32", "status": "affected" }, { "version": "6.1.36", "status": "affected" }, { "version": "6.1.42", "status": "affected" }, { "version": "6.2.1", "status": "affected" }, { "version": "6.2.2", "status": "affected" }, { "version": "6.2.3", "status": "affected" }, { "version": "6.2.25", "status": "affected" }, { "version": "6.2.11", "status": "affected" }, { "version": "6.3.2", "status": "affected" }, { "version": "6.3.3", "status": "affected" }, { "version": "6.3.15", "status": "affected" }, { "version": "6.4.1", "status": "affected" }, { "version": "6.4.2", "status": "affected" }, { "version": "6.4.3", "status": "affected" }, { "version": "6.5.1", "status": "affected" }, { "version": "6.5.2", "status": "affected" }, { "version": "6.5.3", "status": "affected" }, { "version": "6.5.25", "status": "affected" }, { "version": "6.5.26", "status": "affected" }, { "version": "6.5.28", "status": "affected" }, { "version": "6.5.29", "status": "affected" }, { "version": "6.5.32", "status": "affected" }, { "version": "6.5.33", "status": "affected" }, { "version": "6.6.2", "status": "affected" }, { "version": "6.6.3", "status": "affected" }, { "version": "6.6.25", "status": "affected" }, { "version": "6.6.4", "status": "affected" }, { "version": "7.0.1", "status": "affected" }, { "version": "7.0.2", "status": "affected" }, { "version": "7.0.12", "status": "affected" }, { "version": "7.0.14", "status": "affected" }, { "version": "7.1.1", "status": "affected" }, { "version": "7.1.15", "status": "affected" }, { "version": "7.1.2", "status": "affected" }, { "version": "7.1.3", "status": "affected" }, { "version": "6.7.1", "status": "affected" }, { "version": "6.7.2", "status": "affected" }, { "version": "6.7.3", "status": "affected" }, { "version": "6.7.4", "status": "affected" }, { "version": "7.2.0", "status": "affected" }, { "version": "7.2.1", "status": "affected" }, { "version": "7.2.2", "status": "affected" }, { "version": "7.3.1", "status": "affected" }, { "version": "7.3.15", "status": "affected" }, { "version": "7.3.2", "status": "affected" }, { "version": "7.3.3", "status": "affected" }, { "version": "7.3.5", "status": "affected" }, { "version": "7.3.6", "status": "affected" }, { "version": "7.4.1", "status": "affected" }, { "version": "7.4.2", "status": "affected" }, { "version": "6.8.1", "status": "affected" }, { "version": "6.8.2", "status": "affected" }, { "version": "7.5.1", "status": "affected" }, { "version": "7.5.3", "status": "affected" }, { "version": "7.5.2", "status": "affected" }, { "version": "7.5.4", "status": "affected" }, { "version": "7.5.5", "status": "affected" }, { "version": "7.6.1", "status": "affected" }, { "version": "7.6.2", "status": "affected" }, { "version": "7.7.1", "status": "affected" }, { "version": "7.7.2", "status": "affected" }, { "version": "7.7.21", "status": "affected" }, { "version": "6.9.1", "status": "affected" }, { "version": "6.9.2", "status": "affected" }, { "version": "7.8.1", "status": "affected" }, { "version": "7.8.2", "status": "affected" }, { "version": "7.9.1", "status": "affected" }, { "version": "7.9.2", "status": "affected" }, { "version": "7.9.21", "status": "affected" }, { "version": "7.10.1", "status": "affected" }, { "version": "7.10.2", "status": "affected" }, { "version": "7.11.1", "status": "affected" } ] } ] } } }
