Multiple vulnerabilities have been reported in GetSimple CMS, which can be exploited by malicious people to disclose potentially sensitive information, conduct cross-site scripting and script insertion attacks, and compromise a vulnerable system.
1) Input passed via multiple parameters to multiple scripts is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
List of affected scripts and parameters:
<a href="http://[host]/admin/backup-edit.php?id
" target="_blank">http://[host]/admin/backup-edit.php?id
</a>
<a href="http://[host]/admin/edit.php?title&menu
" target="_blank">http://[host]/admin/edit.php?title&menu
</a>
<a href="http://[host]/admin/filebrowser.php?returnid
" target="_blank">http://[host]/admin/filebrowser.php?returnid
</a>
This vulnerability is confirmed in version 3.2.0. Prior versions may also be affected.
2) Certain unspecified input related to the $LANG Settings is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site if malicious data is viewed.
3) Certain unspecified input related to error_checking is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
4) Some unspecified errors related to the frontend and ajax.php can be exploited to gain knowledge of potentially sensitive information via directory traversal sequences.
5) An unspecified error related to loadtab.php can be exploited to execute arbitrary code.
The vulnerabilities #2 through #5 are reported in versions prior to 3.2.1.
