Huawei PC client software HiSuite 4.0.5.300OVE has an information leak vulnerability; an attacker who can log in to the system can copy out the user's proxy password, causing information leaks.

Huawei PC client software HiSuite 4.0.5.300OVE has a dynamic link library (DLL) hijack vulnerability; an attacker can make the system load malicious DLL files to execute arbitrary code.

Huawei PC client software HiSuite 4.0.5.300OVE uses insecure HTTP for upgrade software package download and does not check the integrity of the software package before installing; an attacker can launch an MITM attack to interrupt or replace the downloaded software package and further compromise the PC.

Huawei HiSuite before 4.0.4.204ove (Out of China) and before 4.0.4.301 (China) use a weak ACL (FILEWRITEDATA for BUILTIN\Users) for the HiSuite service directory, which allows local users to gain SYSTEM privileges via a Trojan horse (1) SspiCli.dll or (2) USERENV.dll file or possibly other unspecified DLL files.

Huawei HiSuite (In China) before 4.0.4.301 and (Out of China) before 4.0.4.204ove allows remote attackers to install arbitrary apps on a connected phone via unspecified vectors.

HiSuite 9.1.0.300 versions and earlier contains a DLL hijacking vulnerability. This vulnerability exists due to some DLL file is loaded by HiSuite improperly. And it allows an attacker to load this DLL file of the attacker's choosing that could execute arbitrary code.

HiSuite with 9.1.0.305 and earlier versions and 9.1.0.305(MAC) and earlier versions and HwBackup with earlier versions before 9.1.1.308 have a brute forcing encrypted backup data vulnerability. Huawei smartphone user backup information can be obtained by brute forcing the password for encrypting the backup.

P30, P30 Pro, Mate 20 smartphones with software of versions earlier than ELLE-AL00B 9.1.0.193(C00E190R2P1), versions earlier than VOGUE-AL00A 9.1.0.193(C00E190R2P1), versions earlier than Hima-AL00B 9.1.0.135(C00E133R2P1) and HiSuite with versions earlier than HiSuite 9.1.0.305 have a version downgrade vulnerability. The device and HiSuite software do not validate the upgrade package sufficiently, so that the system of smartphone can be downgraded to an older version.

P30, P30 Pro, Mate 20 smartphones with software of versions earlier than ELLE-AL00B 9.1.0.193(C00E190R2P1), versions earlier than VOGUE-AL00A 9.1.0.193(C00E190R2P1), versions earlier than Hima-AL00B 9.1.0.135(C00E133R2P1) and HiSuite with versions earlier than HiSuite 9.1.0.305 have a version downgrade vulnerability. The device and HiSuite software do not validate the upgrade package sufficiently, so that the system of smartphone can be downgraded to an older version.

Earlier than HiSuite 10.1.0.500 have a DLL hijacking vulnerability. This vulnerability exists due to some DLL file is loaded by HiSuite improperly. And it allows an attacker to load this DLL file of the attacker's choosing.
