Description

Dell KACE K1000 management appliance version 5.5.90545, and possibly earlier versions, contains a cross-site scripting (XSS) vulnerability. The “LABEL_ID” parameter in the “adminui/user_list.php” page is vulnerable.

Impact

A remote unauthenticated attacker may be able to execute arbitrary script in the context of the end-user’s browser session.

---

Solution

Dell has provided this response to the vulnerability. Also, please consider the following workaround.

---

Restrict access

As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent XSS attacks since the attack comes as an HTTP request from a legitimate user’s host. Restricting access would prevent an attacker from accessing the interface using stolen credentials from a blocked network location.
