The CIDAM Protocol on some Huawei Products has multiple input validation vulnerabilities due to insufficient validation of specific messages when the protocol is implemented. An authenticated remote attacker could send a malicious message to a target system. Successful exploit could allow the attacker to tamper with business and make the system abnormal. Affected Huawei Products are: DP300 versions V500R002C00, V500R002C00B010, V500R002C00B011, V500R002C00B012, V500R002C00B013, V500R002C00B014, V500R002C00B017, V500R002C00B018, V500R002C00SPC100, V500R002C00SPC200, V500R002C00SPC300, V500R002C00SPC400, V500R002C00SPC500, V500R002C00SPC600, V500R002C00SPC800, V500R002C00SPC900, V500R002C00SPCa00; RP200 versions V500R002C00SPC200, V600R006C00, V600R006C00SPC200, V600R006C00SPC300, V600R006C00SPC400, V600R006C00SPC500; TE30 versions V100R001C10SPC300, V100R001C10SPC500, V100R001C10SPC600, V100R001C10SPC700B010, V500R002C00SPC200, V500R002C00SPC500, V500R002C00SPC600, V500R002C00SPC700, V500R002C00SPC900, V500R002C00SPCb00, V600R006C00, V600R006C00SPC200, V600R006C00SPC300, V600R006C00SPC400, V600R006C00SPC500; TE40 versions V500R002C00SPC600, V500R002C00SPC700, V500R002C00SPC900, V500R002C00SPCb00, V600R006C00, V600R006C00SPC200, V600R006C00SPC300, V600R006C00SPC400, V600R006C00SPC500; TE50 versions V500R002C00SPC600, V500R002C00SPC700, V500R002C00SPCb00, V600R006C00, V600R006C00SPC200, V600R006C00SPC300, V600R006C00SPC400, V600R006C00SPC500; TE60 versions V100R001C10, V100R001C10B001, V100R001C10B002, V100R001C10B010, V100R001C10B011, V100R001C10B012, V100R001C10B013, V100R001C10B014, V100R001C10B016, V100R001C10B017, V100R001C10B018, V100R001C10B019, V100R001C10SPC400, V100R001C10SPC500, V100R001C10SPC600, V100R001C10SPC700, V100R001C10SPC800B011, V100R001C10SPC900, V500R002C00, V500R002C00B010, V500R002C00B011, V500R002C00SPC100, V500R002C00SPC200, V500R002C00SPC300, V500R002C00SPC600, V500R002C00SPC700, V500R002C00SPC800, V500R002C00SPC900, V500R002C00SPCa00, V500R002C00SPCb00, V500R002C00SPCd00, V500R002C00SPCe00, V600R006C00, V600R006C00SPC100, V600R006C00SPC200, V600R006C00SPC300, V600R006C00SPC400, V600R006C00SPC500; eSpace U1981 version V200R003C20SPC900.
