There is an information leakage vulnerability in some Huawei products. An unauthenticated, adjacent attacker could exploit this vulnerability to decrypt data. Successful exploitation may leak information randomly. Affected product versions include: Anne-AL00 Versions earlier than 9.1.0.331(C675E9R1P3T8); Berkeley-L09 Versions earlier than 10.0.1.1(C675R1); CD16-10 Versions earlier than 10.0.2.8; CD17-10 Versions earlier than 10.0.2.8; CD17-16 Versions earlier than 10.0.2.8; CD18-10 Versions earlier than 10.0.2.8; CD18-16 Versions earlier than 10.0.2.8; Columbia-TL00B Versions earlier than 9.0.0.187(C01E181R1P20T8); E6878-370 Versions earlier than 10.0.5.1(H610SP10C00); HUAWEI P30 lite Versions earlier than 10.0.0.185(C605E3R1P3), Versions earlier than 10.0.0.197(C432E8R2P7); HUAWEI nova 4e Versions earlier than 10.0.0.158(C00E64R1P9); Honor 10 Lite 9.0.1.113(C675E11R1P12); LelandP-L22A Versions earlier than 9.1.0.166(C675E5R1P4T8); Marie-AL00AX Versions earlier than 10.0.0.158(C00E64R1P9); Marie-AL00AY Versions earlier than 10.0.0.158(C00E64R1P9); Marie-AL00BX Versions earlier than 10.0.0.158(C00E64R1P9); Marie-L03BX Versions earlier than 10.0.0.188(C605E5R1P1); Marie-L21BX Versions earlier than 10.0.0.188(C432E4R4P1), Versions earlier than 10.0.0.188(C461E5R3P1); Marie-L22BX Versions earlier than 10.0.0.188(C636E3R3P1); Marie-L23BX Versions earlier than 10.0.0.188(C605E5R1P1); TC5200-16 Versions earlier than 10.0.2.8; WS5200-11 Versions earlier than 10.0.2.8; WS5200-12 Versions earlier than 10.0.2.23; WS5200-16 Versions earlier than 10.0.2.8; WS5200-17 Versions earlier than 10.0.2.23; WS5800-10 Versions earlier than 10.0.3.27; WS6500-10 Versions earlier than 10.0.2.8; WS6500-16 Versions earlier than 10.0.2.8

Some Huawei home routers have an input validation vulnerability. Due to input parameter is not correctly verified, an attacker can exploit this vulnerability by sending special constructed packets to obtain files in the device and upload files to some directories.

Some Huawei home routers have an improper authorization vulnerability. Due to improper authorization of certain programs, an attacker can exploit this vulnerability to execute uploaded malicious files and escalate privilege.

Huawei home gateway products HiRouter-CD20 and WS5200 with the versions before HiRouter-CD20-10 1.9.6 and the versions before WS5200-10 1.9.6 have a path traversal vulnerability. Due to the lack of validation while these home gateway products install APK plugins, an attacker tricks a user into installing a malicious APK plugin, and plugin can overwrite arbitrary file of devices. Successful exploit may result in arbitrary code execution or privilege escalation.
