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).

php-mod/curl (a wrapper of the PHP cURL extension) before 2.3.2 allows XSS via the post_file_path_upload.php key parameter and the POST data to post_multidimensional.php.

qs before 6.10.3, as used in Express before 4.17.3 and other products, allows attackers to cause a Node process hang for an Express application because an __ proto__ key can be used. In many typical Express use cases, an unauthenticated remote attacker can place the attack payload in the query string of the URL that is used to visit the application, such as a[__proto__]=b&a[__proto__]&a[length]=100000000. The fix was backported to qs 6.9.7, 6.8.3, 6.7.3, 6.6.1, 6.5.3, 6.4.1, 6.3.3, and 6.2.4 (and therefore Express 4.17.3, which has "deps: qs@6.9.7" in its release description, is not vulnerable).

Weak File and Folder Permissions vulnerability in CLUSTERPRO X 5.0 for Windows and earlier, EXPRESSCLUSTER X 5.0 for Windows and earlier, CLUSTERPRO X 5.0 SingleServerSafe for Windows and earlier, EXPRESSCLUSTER X 5.0 SingleServerSafe for Windows and earlier allows a remote unauthenticated attacker to overwrite existing files on the file system and to potentially execute arbitrary code.
