Dahua IP cameras and related products contain an authentication bypass vulnerability when the loopback device is specified by the client during authentication.

Dahua IP cameras and related products contain an authentication bypass vulnerability when the NetKeyboard type argument is specified by the client during authentication.

Dahua IP camera products using firmware versions prior to V2.400.0000.14.R.20170713 include a version of the Sonia web interface that may be vulnerable to a stack buffer overflow. Dahua IP camera products include an application known as Sonia (/usr/bin/sonia) that provides the web interface and other services for controlling the IP camera remotely. Versions of Sonia included in firmware versions prior to DHIPC-Consumer-Zi-ThemisEngPV2.408.0000.11.R.20170621 do not validate input data length for the 'password' field of the web interface. A remote, unauthenticated attacker may submit a crafted POST request to the IP camera's Sonia web interface that may lead to out-of-bounds memory operations and loss of availability or remote code execution. The issue was originally identified by the researcher in firmware version DHIPC-HX1X2X-ThemisEngSpnFrnNV2.400.0000.30.R.20160803.
