The Linear eMerge e3-Series through version 1.00-07 is vulnerable to an OS command injection vulnerability. A remote and unauthenticated attacker can execute arbitrary OS commands via the login_id parameter when invoking the forgot_password functionality over HTTP.

Nortek Linear eMerge E3-Series 0.32-07p devices are vulnerable to /card_scan.php?CardFormatNo= XSS with session fixation (via PHPSESSID) when they are chained together. This would allow an attacker to take over an admin account or a user account.

Nortek Linear eMerge E3-Series devices before 0.32-08f allow an unauthenticated attacker to inject OS commands via ReaderNo. NOTE: this issue exists because of an incomplete fix for CVE-2019-7256.

Nortek Linear eMerge E3-Series devices through 0.32-09c place admin credentials in /test.txt that allow an attacker to open a building's doors. (This occurs in situations where the CVE-2019-7271 default credentials have been changed.)
