An attacker could exploit this vulnerability by sending a crafted MPLS echo-request to an IP address on an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes, which could result in a device reload and a DoS condition.", "affected": [ { "vendor": "Cisco", "product": "Cisco NX-OS Software", "defaultStatus": "unknown", "versions": [ { "version": "9.3(2)", "status": "affected" }, { "version": "9.3(1)", "status": "affected" }, { "version": "9.3(1z)", "status": "affected" }, { "version": "9.3(3)", "status": "affected" }, { "version": "9.3(4)", "status": "affected" }, { "version": "9.3(5)", "status": "affected" }, { "version": "9.3(6)", "status": "affected" }, { "version": "9.3(5w)", "status": "affected" }, { "version": "9.3(7)", "status": "affected" }, { "version": "9.3(7k)", "status": "affected" }, { "version": "9.3(7a)", "status": "affected" }, { "version": "9.3(8)", "status": "affected" }, { "version": "9.3(9)", "status": "affected" }, { "version": "9.3(10)", "status": "affected" }, { "version": "10.3(1)", "status": "affected" }, { "version": "10.3(2)", "status": "affected" }, { "version": "9.3(11)", "status": "affected" }, { "version": "10.3(3)", "status": "affected" }, { "version": "9.3(12)", "status": "affected" }, { "version": "10.4(1)", "status": "affected" }, { "version": "10.3(99w)", "status": "affected" }, { "version": "10.3(3w)", "status": "affected" }, { "version": "10.3(99x)", "status": "affected" }, { "version": "10.3(3o)", "status": "affected" }, { "version": "10.3(4)", "status": "affected" }, { "version": "10.3(3p)", "status": "affected" }, { "version": "10.3(4a)", "status": "affected" }, { "version": "10.4(2)", "status": "affected" }, { "version": "10.3(3q)", "status": "affected" }, { "version": "9.3(13)", "status": "affected" }, { "version": "10.3(5)", "status": "affected" }, { "version": "10.4(3)", "status": "affected" }, { "version": "10.3(3x)", "status": "affected" }, { "version": "10.3(4g)", "status": "affected" }, { "version": "10.5(1)", "status": "affected" }, { "version": "10.3(3r)", "status": "affected" }, { "version": "10.3(6)", "status": "affected" }, { "version": "9.3(14)", "status": "affected" }, { "version": "10.4(4)", "status": "affected" }, { "version": "10.3(4h)", "status": "affected" }, { "version": "10.5(2)", "status": "affected" }, { "version": "10.3(7)", "status": "affected" }, { "version": "10.4(5)", "status": "affected" }, { "version": "10.5(3)", "status": "affected" }, { "version": "9.3(15)", "status": "affected" }, { "version": "10.4(4g)", "status": "affected" }, { "version": "10.5(4)", "status": "affected" }, { "version": "10.6(1)", "status": "affected" }, { "version": "10.5(3t)", "status": "affected" }, { "version": "10.3(8)", "status": "affected" }, { "version": "10.4(6)", "status": "affected" }, { "version": "10.5(3s)", "status": "affected" }, { "version": "10.5(3e)", "status": "affected" }, { "version": "10.5(3o)", "status": "affected" }, { "version": "9.3(16)", "status": "affected" }, { "version": "10.6(1s)", "status": "affected" }, { "version": "10.6(2)", "status": "affected" }, { "version": "10.5(3p)", "status": "affected" }, { "version": "10.3(9)", "status": "affected" }, { "version": "10.6(2s)", "status": "affected" }, { "version": "10.6(3)", "status": "affected" }, { "version": "10.4(7)", "status": "affected" }, { "version": "10.5(5)", "status": "affected" }, { "version": "9.3(17)", "status": "affected" }, { "version": "10.6(2n)", "status": "affected" }, { "version": "10.6(3s)", "status": "affected" } ] } ] } } }
