Webmin 1.840 / 1.880 LFI

critical Nessus Plugin ID 146496

Language:

Synopsis

The remote web server is affected by a local file inclusion vulnerability.

Description

A local file inclusion vulnerability exists in Webmin 1.840 and 1.880 when the default Yes setting of 'Can view any file as a log file' is enabled. As a result of weak default configuration settings, limited users have full access rights to the underlying Unix system files, allowing the user to read sensitive data from the local system (using Local File Include) such as the '/etc/shadow' file via a 'GET /syslog/save_log.cgi?view=1&file=/etc/shadow' request.

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

Solution

Refer to vendor documentation.
