Technical Description

Multiple vulnerabilities have been identified in ezContents, which could be exploited by remote attackers to compromise a vulnerable server or execute arbitrary scripting code.

The first issue is due to an input validation error in the "headeruserdata.php" script that fails to properly validate the "groupname" parameter before being used in SQL statements, which could be exploited by malicious people to conduct SQL injection attacks.

The second vulnerability is due to input validation errors in the "moduleExternalLink()" [modules/moduleSec.php], "isExternalLink()" [include/functions.php], and "adminExternalLink()" [admin/adminbutton.php] functions that do not validate certain variables (e.g. "GLOBALS[admin_home]"), which may be exploited by remote attackers to include local or remote scripts with the privileges of the web server.

The third flaw is due to an input validation error in the "loginreg2.php" script that fails to properly validate the "subgroupname" parameter, which could be exploited by attackers to cause malicious scripting code to be executed by the user's browser.
