Vulnerabilidades

Some Dahua software products have a vulnerability of unauthenticated restart of remote DSS Server. After bypassing the firewall access control policy, by sending a specific crafted packet to the vulnerable interface, an attacker could unauthenticated restart of remote DSS Server.

Some Dahua software products have a vulnerability of unauthenticated enable or disable SSHD service. After bypassing the firewall access control policy, by sending a specific crafted packet to the vulnerable interface, an attacker could enable or disable the SSHD service.

Some Dahua software products have a vulnerability of server-side request forgery (SSRF). An Attacker can access internal resources by concatenating links (URL) that conform to specific rules.

Some Dahua software products have a vulnerability of sensitive information leakage. After obtaining the permissions of administrators, by sending a specific crafted packet to the vulnerable interface, an attacker can obtain the debugging information.

Some Dahua software products have a vulnerability of unrestricted upload of file. After obtaining the permissions of administrators, by sending a specific crafted packet to the vulnerable interface, an attacker can upload arbitrary files.

Some Dahua software products have a vulnerability of unrestricted download of file. After obtaining the permissions of ordinary users, by sending a specific crafted packet to the vulnerable interface, an attacker can download arbitrary files.

Some Dahua software products have a vulnerability of using of hard-coded cryptographic key. An attacker can obtain the AES crypto key by exploiting this vulnerability.

Some Dahua software products have a vulnerability of unauthenticated request of AES crypto key. An attacker can obtain the AES crypto key by sending a specific crafted packet to the vulnerable interface.

Some Dahua software products have a vulnerability of unauthenticated request of MQTT credentials. An attacker can obtain encrypted MQTT credentials by sending a specific crafted packet to the vulnerable interface (the credentials cannot be directly exploited).

When an attacker uses a man-in-the-middle attack to sniff the request packets with success logging in through ONVIF, he can log in to the device by replaying the user's login packet.

If the user enables the https function on the device, an attacker can modify the user’s request data packet through a man-in-the-middle attack ,Injection of a malicious URL in the Host: header of the HTTP Request results in a 302 redirect to an attacker-controlled page.

When an attacker uses a man-in-the-middle attack to sniff the request packets with success logging in, the attacker could log in to the device by replaying the user's login packet.

When an attacker obtaining the administrative account and password, or through a man-in-the-middle attack, the attacker could send a specified crafted packet to the vulnerable interface then lead the device to crash.

Some Dahua products have access control vulnerability in the password reset process. Attackers can exploit this vulnerability through specific deployments to reset device passwords.

The identity authentication bypass vulnerability found in some Dahua products during the login process. Attackers can bypass device identity authentication by constructing malicious data packets.

The identity authentication bypass vulnerability found in some Dahua products during the login process. Attackers can bypass device identity authentication by constructing malicious data packets.

Some Dahua products with Build time before December 2019 have Session ID predictable vulnerabilities. During normal user access, an attacker can use the predicted Session ID to construct a data packet to attack the device.

Attackers can obtain Cloud Key information from the Dahua Web P2P control in specific ways. Cloud Key is used to authenticate the connection between the client tool and the platform. An attacker may use the leaked Cloud Key to impersonate the client to connect to the platform, resulting in additional consumption of…

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…

Some products of Dahua have Denial of Service vulnerabilities. After the successful login of the legal account, the attacker sends a specific log query command, which may cause the device to go down.

Some Dahua products have buffer overflow vulnerabilities. After the successful login of the legal account, the attacker sends a specific DDNS test command, which may cause the device to go down.

Some Dahua products have information leakage issues. Attackers can obtain the IP address and device model information of the device by constructing malicious data packets. Affected products include: IPC-HDW1X2X,IPC-HFW1X2X,IPC-HDW2X2X,IPC-HFW2X2X,IPC-HDW4X2X,IPC-HFW4X2X,IPC-HDBW4X2X,IPC-HDW5X2X,IPC-HFW5X2X for…

Some of Dahua's Debug functions do not have permission separation. Low-privileged users can use the Debug function after logging in. Affected products include: IPC-HDW1X2X,IPC-HFW1X2X,IPC-HDW2X2X,IPC-HFW2X2X,IPC-HDW4X2X,IPC-HFW4X2X,IPC-HDBW4X2X,IPC-HDW5X2X,IPC-HFW5X2X for versions which Build time is before August…

Some Dahua products have the problem of denial of service during the login process. An attacker can cause a device crashed by constructing a malicious packet. Affected products include: IPC-HDW1X2X,IPC-HFW1X2X,IPC-HDW2X2X,IPC-HFW2X2X,IPC-HDW4X2X,IPC-HFW4X2X,IPC-HDBW4X2X,IPC-HDW5X2X,IPC-HFW5X2X for versions which Build…

The specific fields of CGI interface of some Dahua products are not strictly verified, an attacker can cause a buffer overflow by constructing malicious packets. Affected products include: IPC-HDW1X2X,IPC-HFW1X2X,IPC-HDW2X2X,IPC-HFW2X2X,IPC-HDW4X2X,IPC-HFW4X2X,IPC-HDBW4X2X,IPC-HDW5X2X,IPC-HFW5X2X for versions which…
