Synopsis

The remote web server is affected by multiple vulnerabilities.

Description

According to its self-reported version, the version of Webmin running on the remote host may be affected by multiple vulnerabilities, including the following:

- Arbitrary command execution can occur in Webmin through 1.962. Any user authorized for the Package Updates module can execute arbitrary commands with root privileges via vectors involving %0A and %0C. NOTE: this issue exists because of an incomplete fix for CVE-2019-12840. (CVE-2020-35606)

- miniserv.pl in Webmin 1.962 on Windows mishandles special characters in query arguments to the CGI program.
(CVE-2020-35769)

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

Solution

Upgrade to Webmin 1.970 or later.
