Webmin < 2.650 Reflected Cross-Site Scripting

critical Web App Scanning Plugin ID 115746

Synopsis

Webmin < 2.650 Reflected Cross-Site Scripting

Description

According to its self-reported version, the Webmin install hosted on the remote host is prior to 2.650. It is, therefore, affected by a Reflected Cross-Site Scripting (XSS) vulnerability in the Webmin Configuration module. A Webmin user who clicks on a malicious link to their server could have attacker-controlled commands executed (CVE-2026-49243).

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to Webmin version 2.650 or latest.
