Detects anomalous activity on Dahua camera management interfaces (port 37777) where multiple failed authentication attempts are followed by administrative configuration actions without a corresponding successful credentialed login, suggesting exploitation of authentication-bypass vulnerabilities such as CVE-2021-33044 and CVE-2021-33045.
This rule detects a specific network exploit attempt targeting Dahua devices (CVE-2021-33045), where an attacker attempts to bypass authentication by manipulating the login parameters, specifically by forcing the system to interpret requests as coming from the local loopback interface.
This rule detects an attempt to exploit CVE-2021-33045, an authentication bypass vulnerability in certain Dahua products. An attacker can bypass authentication by sending a crafted HTTP POST request to the application, specifically using a loopback authentication type with a local IP address (127.0.0.1) in the login payload.
Detects attempts to exploit CVE-2021-33045, an authentication bypass vulnerability in certain Dahua camera firmware. The attack involves sending a crafted login request containing 'global.login', 'clientType', and 'Loopback' parameters, which allows an attacker to bypass authentication mechanisms.
This rule detects attempts to exploit the authentication bypass vulnerability in Dahua firmware (CVE-2021-33045) via the JSON-RPC interface. The attacker attempts to manipulate the 'loginType' and 'ipAddr' fields, specifically using 'Loopback' as the login type and '127.0.0.1' as the IP address to bypass security controls.
This rule detects an attempted authentication bypass vulnerability (CVE-2021-33045) targeting Dahua NetKeyboard devices. The exploit involves a specific HTTP request structure to the 'global.login' endpoint, where the 'loginType' parameter is set to 'Loopback' and the 'ipAddr' is set to '127.0.0.1', attempting to leverage internal loopback logic to circumvent authentication mechanisms.
Detects an attempt to exploit CVE-2021-33045 in Dahua devices, where an attacker sends a malicious JSON-RPC request to bypass authentication by leveraging the 'Loopback' login type and targeting the '127.0.0.1' address in the 'ipAddr' parameter.
This rule detects exploitation attempts against CVE-2021-33045 in Dahua devices. It identifies network traffic where a 'global.login' RPC request uses the 'Loopback' login type with a spoofed source IP address of '127.0.0.1' within the request body, while the actual TCP source address of the packet originates from a remote/external location. This technique is used to bypass authentication mechanisms.
