Description

This security bulletin contains information about 1 security vulnerability.


1) Cross-site scripting (CVE-ID: CVE-2019-12949)

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via the "timePeriod" parameter to diag_command.php and rrd_fetch_json.php scripts. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
