An attacker with an on-path position between the ACI sites could exploit this vulnerability by intercepting intersite encrypted traffic and using cryptanalytic techniques to break the encryption. A successful exploit could allow the attacker to read or modify the traffic that is transmitted between the sites.\r\n\r Cisco has not released and will not release software updates that address this vulnerability.", "affected": [ { "vendor": "Cisco", "product": "Cisco NX-OS System Software in ACI Mode", "versions": [ { "version": "14.0(1h)", "status": "affected" }, { "version": "14.0(2c)", "status": "affected" }, { "version": "14.0(3d)", "status": "affected" }, { "version": "14.0(3c)", "status": "affected" }, { "version": "14.1(1i)", "status": "affected" }, { "version": "14.1(1j)", "status": "affected" }, { "version": "14.1(1k)", "status": "affected" }, { "version": "14.1(1l)", "status": "affected" }, { "version": "14.1(2g)", "status": "affected" }, { "version": "14.1(2m)", "status": "affected" }, { "version": "14.1(2o)", "status": "affected" }, { "version": "14.1(2s)", "status": "affected" }, { "version": "14.1(2u)", "status": "affected" }, { "version": "14.1(2w)", "status": "affected" }, { "version": "14.1(2x)", "status": "affected" }, { "version": "14.2(1i)", "status": "affected" }, { "version": "14.2(1j)", "status": "affected" }, { "version": "14.2(1l)", "status": "affected" }, { "version": "14.2(2e)", "status": "affected" }, { "version": "14.2(2f)", "status": "affected" }, { "version": "14.2(2g)", "status": "affected" }, { "version": "14.2(3j)", "status": "affected" }, { "version": "14.2(3l)", "status": "affected" }, { "version": "14.2(3n)", "status": "affected" }, { "version": "14.2(3q)", "status": "affected" }, { "version": "14.2(4i)", "status": "affected" }, { "version": "14.2(4k)", "status": "affected" }, { "version": "14.2(4o)", "status": "affected" }, { "version": "14.2(4p)", "status": "affected" }, { "version": "14.2(5k)", "status": "affected" }, { "version": "14.2(5l)", "status": "affected" }, { "version": "14.2(5n)", "status": "affected" }, { "version": "14.2(6d)", "status": "affected" }, { "version": "14.2(6g)", "status": "affected" }, { "version": "14.2(6h)", "status": "affected" }, { "version": "14.2(6l)", "status": "affected" }, { "version": "14.2(7f)", "status": "affected" }, { "version": "14.2(7l)", "status": "affected" }, { "version": "14.2(6o)", "status": "affected" }, { "version": "14.2(7q)", "status": "affected" }, { "version": "14.2(7r)", "status": "affected" }, { "version": "14.2(7s)", "status": "affected" }, { "version": "14.2(7t)", "status": "affected" }, { "version": "14.2(7u)", "status": "affected" }, { "version": "14.2(7v)", "status": "affected" }, { "version": "14.2(7w)", "status": "affected" }, { "version": "15.0(1k)", "status": "affected" }, { "version": "15.0(1l)", "status": "affected" }, { "version": "15.0(2e)", "status": "affected" }, { "version": "15.0(2h)", "status": "affected" }, { "version": "15.1(1h)", "status": "affected" }, { "version": "15.1(2e)", "status": "affected" }, { "version": "15.1(3e)", "status": "affected" }, { "version": "15.1(4c)", "status": "affected" }, { "version": "15.2(1g)", "status": "affected" }, { "version": "15.2(2e)", "status": "affected" }, { "version": "15.2(2f)", "status": "affected" }, { "version": "15.2(2g)", "status": "affected" }, { "version": "15.2(2h)", "status": "affected" }, { "version": "15.2(3e)", "status": "affected" }, { "version": "15.2(3f)", "status": "affected" }, { "version": "15.2(3g)", "status": "affected" }, { "version": "15.2(4d)", "status": "affected" }, { "version": "15.2(4e)", "status": "affected" }, { "version": "15.2(5c)", "status": "affected" }, { "version": "15.2(5d)", "status": "affected" }, { "version": "15.2(5e)", "status": "affected" }, { "version": "15.2(4f)", "status": "affected" }, { "version": "15.2(6e)", "status": "affected" }, { "version": "15.2(6g)", "status": "affected" }, { "version": "15.2(7f)", "status": "affected" }, { "version": "15.2(7g)", "status": "affected" }, { "version": "15.2(8d)", "status": "affected" }, { "version": "15.2(8e)", "status": "affected" }, { "version": "15.2(8f)", "status": "affected" }, { "version": "15.2(8g)", "status": "affected" }, { "version": "15.2(8h)", "status": "affected" }, { "version": "16.0(1g)", "status": "affected" }, { "version": "16.0(1j)", "status": "affected" }, { "version": "16.0(2h)", "status": "affected" }, { "version": "16.0(2j)", "status": "affected" }, { "version": "16.0(3d)", "status": "affected" }, { "version": "16.0(3e)", "status": "affected" }, { "version": "15.3(1d)", "status": "affected" } ] } ] } } }
