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.
