Webmin : Security Vulnerabilities, CVEs, (Directory traversal)

An issue was discovered 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.

Directory traversal vulnerability in Webmin before 1.280, when run on Windows, allows remote attackers to read arbitrary files via \ (backslash) characters in the URL to certain directories under the web root, such as the image directory.

Directory traversal vulnerability in edit_action.cgi of Webmin Directory 0.91 allows attackers to gain privileges via a '..' (dot dot) in the argument.
