CVE-2020-11625 Information

Description

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.
