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 un-throttled ICMP requests on remote DSS Server. After bypassing the firewall access control policy, by sending a specific crafted packet to the vulnerable interface, an attacker could exploit the victim server to launch ICMP request attack to the designated target host.

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).

Dahua DVR 2.608.0000.0 and 2.608.GV00.0 allows remote attackers to bypass authentication and obtain sensitive information including user credentials, change user passwords, clear log files, and perform other actions via a request to TCP port 37777.

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 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.

Dahua DVR appliances have a small value for the maximum password length, which makes it easier for remote attackers to obtain access via a brute-force attack.

Dahua DVR appliances have a hardcoded password for (1) the root account and (2) an unspecified "backdoor" account, which makes it easier for remote attackers to obtain administrative access via authorization requests involving (a) ActiveX, (b) a standalone client, or (c) unknown other vectors.

Dahua DVR appliances do not properly restrict UPnP requests, which makes it easier for remote attackers to obtain access via vectors involving a replay attack against the TELNET port.

Dahua DVR appliances use a password-hash algorithm with a short hash length, which makes it easier for context-dependent attackers to discover cleartext passwords via a brute-force attack.

The authorization implementation on Dahua DVR appliances accepts a hash string representing the current date for the role of a master password, which makes it easier for remote attackers to obtain administrative access and change the administrator password via requests involving (1) ActiveX, (2) a standalone client, or (3) unspecified other vectors, a different vulnerability than CVE-2013-3612.

A vulnerability has been found in Dahua products.  After obtaining the administrator's username and password, the attacker can send a carefully crafted data packet to the interface with vulnerabilities, causing the device to crash.

Some Dahua embedded products have a vulnerability of unauthorized modification of the device timestamp. By sending a specially crafted packet to the vulnerable interface, an attacker can modify the device system time.

Dahua Smart Parking Management image server-side request forgery

A vulnerability has been found in Dahua Smart Parking Management up to 20230528 and classified as problematic. This vulnerability affects unknown code of the file /ipms/imageConvert/image. The manipulation of the argument fileUrl leads to server-side request forgery. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-230800. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

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.
