Nice (formerly Nortek) Linear eMerge E3-Series 0.32-08f, 0.32-07p, 0.32-07e, 0.32-09c, 0.32-09b, 0.32-09a, and 0.32-08e devices are vulnerable to Stored Cross-Site Scripting (XSS).

Nortek Linear eMerge E3-Series 0.32-08f, 0.32-07p, 0.32-07e, 0.32-09c, 0.32-09b, 0.32-09a, and 0.32-08e were discovered to contain a SQL injection vulnerability via the idt parameter.

Certain Linear eMerge E3-Series devices are vulnerable to XSS via the type parameter (e.g., to the badging/badge_template_v0.php component). This affects 0.32-08f, 0.32-07p, 0.32-07e, 0.32-09c, 0.32-09b, 0.32-09a, and 0.32-08e.

Nortek Linear eMerge E3-Series 0.32-08f, 0.32-07p, 0.32-07e, 0.32-09c, 0.32-09b, 0.32-09a, and 0.32-08e were discovered to contain a cross-site scripting (XSS) vulnerability which is chained with a local session fixation. This vulnerability allows attackers to escalate privileges via unspecified vectors.

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.
