Detailsinfo

A vulnerability was found in AvertX HD438 and HD838 (version unknown). It has been declared as problematic. This vulnerability affects an unknown function of the component Web UI. The manipulation with an unknown input leads to a information exposure vulnerability (User). The CWE definition for the vulnerability is CWE-203. The product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor, which exposes security-relevant information about the state of the product, such as whether a particular operation was successful or not. As an impact it is known to affect confidentiality. CVE summarizes:

An issue was discovered in AvertX Auto focus Night Vision HD Indoor/Outdoor IP Dome Camera HD838 and Night Vision HD Indoor/Outdoor Mini IP Bullet Camera HD438. Failed web UI login attempts elicit different responses depending on whether a user account exists. Because the responses indicate whether a submitted username is valid or not, they make it easier to identify legitimate usernames. If a login request is sent to ISAPI/Security/sessionLogin/capabilities using a username that exists, it will return the value of the salt given to that username, even if the password is incorrect. However, if a login request is sent using a username that is not present in the database, it will return an empty salt value. This allows attackers to enumerate legitimate usernames, facilitating brute-force attacks. NOTE: this is different from CVE-2020-7057.

The weakness was released 07/23/2020. This vulnerability was named CVE-2020-11625 since 04/07/2020. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
