The Windows-based Host Interface Program (WHIP) service on Huawei SmartAX MT882 devices V200R002B022 Arg relies on the client to send a length field that is consistent with a buffer size, which allows remote attackers to cause a denial of service (device outage) or possibly have unspecified other impact via crafted traffic on TCP port 8701.

GlobespanVirata ftpd 1.0, as used on Huawei SmartAX MT882 devices V200R002B022 Arg, allows remote authenticated users to cause a denial of service (device outage) by using the FTP MKD command to create a directory with a long name, and then using certain other commands.

rpwizPppoe.htm in Huawei MT882 V100R002B020 ARG-T running firmware 3.7.9.98 contains a form that does not disable the autocomplete setting for the password parameter, which makes it easier for local users or physically proximate attackers to obtain the password from web browsers that support autocomplete.

Multiple cross-site scripting (XSS) vulnerabilities in multiple scripts in Forms/ in Huawei MT882 V100R002B020 ARG-T running firmware 3.7.9.98 allow remote attackers to inject arbitrary web script or HTML via the (1) BackButton parameter to error_1; (2) wzConnFlag parameter to fresh_pppoe_1; (3) diag_pppindex_argen and (4) DiagStartFlag parameters to rpDiag_argen_1; (5) wzdmz_active and (6) wzdmzHostIP parameters to rpNATdmz_argen_1; (7) wzVIRTUALSVR_endPort, (8) wzVIRTUALSVR_endPortLocal, (9) wzVIRTUALSVR_IndexFlag, (10) wzVIRTUALSVR_localIP, (11) wzVIRTUALSVR_startPort, and (12) wzVIRTUALSVR_startPortLocal parameters to rpNATvirsvr_argen_1; (13) Connect_DialFlag, (14) Connect_DialHidden, and (15) Connect_Flag parameters to rpStatus_argen_1; (16) Telephone_select, and (17) wzFirstFlag parameters to rpwizard_1; and (18) wzConnectFlag parameter to rpwizPppoe_1.
