Vulnerabilidades

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.)

A Command Injection issue was discovered in Nortek Linear eMerge E3 series Versions V0.32-07e and prior. A remote attacker may be able to execute arbitrary code on a target machine with elevated privileges.
