Huawei USG6300 V100R001C30SPC300 and USG6600 with software of V100R001C30SPC500,V100R001C30SPC600,V100R001C30SPC700,V100R001C30SPC800 have a weak algorithm vulnerability. Attackers may exploit the weak algorithm vulnerability to crack the cipher text and cause confidential information leaks on the transmission links.
Huawei Secospace USG6300 with software V500R001C20 and V500R001C20SPC200PWE, Secospace USG6500 with software V500R001C20, Secospace USG6600 with software V500R001C20 and V500R001C20SPC200PWE allow remote attackers with specific permission to log in to a device and deliver a large number of unspecified commands to exhaust memory, causing a DoS condition.
The security policy processing module in Huawei Secospace USG6300 with software V500R001C20SPC100, V500R001C20SPC101, V500R001C20SPC200; Secospace USG6500 with software V500R001C20SPC100, V500R001C20SPC101, V500R001C20SPC200; Secospace USG6600 with software V500R001C20SPC100, V500R001C20SPC101, V500R001C20SPC200 allows authenticated attackers to setup a specific security policy into the devices, causing a buffer overflow and crashing the system.
Buffer overflow in the Smart DNS functionality in the Huawei NGFW Module and Secospace USG6300, USG6500, USG6600, and USG9500 firewalls with software before V500R001C20SPC100 allows remote attackers to cause a denial of service or execute arbitrary code via a crafted packet, related to "illegitimate parameters."
Buffer overflow in the Application Specific Packet Filtering (ASPF) functionality in the Huawei IPS Module, NGFW Module, NIP6300, NIP6600, Secospace USG6300, USG6500, USG6600, USG9500, and AntiDDoS8000 devices with software before V500R001C20SPC100 allows remote attackers to cause a denial of service or execute arbitrary code via a crafted packet, related to "illegitimate parameters."
