Dahua Intelligent Connection Center command injection

A vulnerability has been found in the Dahua Intelligent Connection Center. A remote attacker could send a specially crafted request to the affected system, allowing the attacker to execute arbitrary commands, resulting in remote code execution.

Public Disclosure of Dahua IPC CA Root Certificate Enables Fake Trusted Certificates

A vulnerability has been found in some Dahua products. An attacker may obtain the device’s CA root certificate. If that CA is installed and trusted on client systems, the attacker could issue fraudulent certificates trusted by those clients and undermine the certificate trust chain.

Authenticated Remote Attacker Can Force System Reboot Causing Denial of Service

A vulnerability has been found in some Dahua products could allow an authenticated remote attacker to send a specially crafted packet, triggering an exception that causes the system to reboot unexpectedly, resulting in a denial of service.

Device Reboot via Crafted Packet Leading to Denial of Service on Dahua Products

A vulnerability has been found in some Dahua products could allow an unauthenticated remote attacker to send a specially crafted packet, triggering an exception that causes the system to reboot unexpectedly, resulting in a denial of service.

A vulnerability has been found in Dahua products. Attackers could exploit a buffer overflow vulnerability by sending specially crafted malicious packets, potentially causing service disruption (e.g., crashes) or remote code execution (RCE). Some devices may have deployed protection mechanisms such as Address Space Layout Randomization (ASLR), which reduces the likelihood of successful RCE exploitation. However, denial-of-service (DoS) attacks remain a concern.

A vulnerability exists in certain Dahua embedded products. Third-party malicious attacker with obtained normal user credentials could exploit the vulnerability to access certain data which are restricted to admin privileges, such as system-sensitive files through specific HTTP request. This may cause tampering with admin password, leading to privilege escalation. Systems with only admin account are not affected.

Privilege Escalation via Serial Port Restricted Shell in Dahua NVR/XVR Devices

A vulnerability found in Dahua NVR/XVR device. A third-party malicious attacker with physical access to the device may gain access to a restricted shell via the serial port, and bypasses the shell's authentication mechanism to escalate privileges.

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.
