GEN:SID | 1:1662 |
Message | WEB-MISC /~ftp access |
Summary | This event is generated when an attempt is made to access the home directory of the ftp user via http. |
Impact | Medium - Possible unauthorized file access due a configuration error |
Detailed Information | The FTP server might block access on ftp homedir to (anonymous) users, but the folder can be read using the webserver. Apache UserDir module allows sharing home directory (sub-)folders, a misconfiguration of the webserver or ftp user account may allow unauthorized access to the ftp user directory. |
Affected Systems | |
Attack Scenarios | A FTP server blocks access to the ftp users homedir. A misconfiguration might allow an attacker to access the ftp users home directory. This home folder might contain critical files. |
Ease of Attack | Simple. |
Corrective Action | Visit http://httpd.apache.org/docs for UserDir configuration options or remove UserDir module if not needed. Configure the ftp user to use a non-interactive nologin shell that does not require a home directory. |
