Message | WEB-CGI edit_action.cgi access |
Summary | This event is generated when an attempt is made to access edit_action.cgi on an internal web server. This may indicate an attempt to exploit a directory traversal vulnerability in Webmin 0.91.
|
Impact | Information gathering, possible execution of system utilities to which Webmin has rights.
|
Detailed Information | Webmin is a web-based system administration tool for Linux and UNIX-based operating systems. A malicious user could use directory traversal techniques within an argument sent to the edit_action.cgi script in order to view hidden files on the server or execute programs to which Webmin has security privileges.
|
Affected Systems | Systems running Webmin 0.91.
|
Attack Scenarios | An attacker creates a specially crafted an edit_action.cgi URL and transmits it to a vulnerable server. The attacker can then view or execute any arbitrary file included in the parameter, provided that Webmin has rights to access it.
|
Ease of Attack | Simple. A proof of concept exists.
|
Corrective Action | Upgrade to Webmin 0.92 or higher.
