Synopsis

Webmin < 2.301 Multiple Vulnerabilities

Description

According to its self-reported version, the Webmin install hosted on the remote host is prior to 2.301. It is, therefore, affected by multiple vulnerabilities:

- A vulnerability allows a network traffic loop via spoofed UDP packets on port 10000 (CVE-2024-45692).

- An Authentication Bypass vulnerability exists in the Webmin HTTP server (miniserv.pl) when configured to trust proxy headers, allowing unauthenticated attackers to impersonate any user with a configured SSL client certificate by sending a forged HTTP header (CVE-2026-56020).

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 2.301 or latest.
