USG9500 with versions of V500R001C30SPC100, V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, V500R005C00SPC100, V500R005C00SPC200 have an information leakage vulnerability. Due to improper processing of the initialization vector used in a specific encryption algorithm, an attacker who gains access to this cryptographic primitive may exploit this vulnerability to cause the value of the confidentiality associated with its use to be diminished.

USG9500 with software of V500R001C30SPC100; V500R001C30SPC200; V500R001C30SPC600; V500R001C60SPC500; V500R005C00SPC100; V500R005C00SPC200 have an improper credentials management vulnerability. The software does not properly manage certain credentials. Successful exploit could cause information disclosure or damage, and impact the confidentiality or integrity.

Huawei Secospace USG6600 V500R001C30SPC100, Secospace USG6600 V500R001C30SPC200, Secospace USG6600 V500R001C30SPC300, USG9500 V500R001C30SPC100, USG9500 V500R001C30SPC200, USG9500 V500R001C30SPC300 have a memory leak vulnerability due to memory don't be released when an local authenticated attacker execute special commands many times. An attacker could exploit it to cause memory leak, which may further lead to system exceptions.
