Some vulnerabilities have been reported in CMS Made Simple, which can be exploited by malicious people to conduct cross-site scripting attacks, disclose potentially sensitive information, bypass certain security restrictions, and compromise a vulnerable system.
1) Input passed to the "last_module" parameter in lib/adodb_lite/adodb-perf-module.inc.php is not properly sanitised before being used in a call to "eval()". This can be exploited to inject and execute arbitrary PHP code via a specially crafted parameter value.
Successful exploitation requires that "register_globals" is enabled.
2) Input passed to the "anchor" and "listtag" tags is not properly sanitised before being returned to a user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
3) The application does not properly restrict access to the adduser.php script. This can be exploited to e.g. add new users.
4) The application does not properly restrict access to the admin log. This can be exploited to e.g. disclose potentially sensitive information.
Vulnerability #1 is confirmed in version 126.96.36.199. Other versions may also be affected.
Solution: Update to version 188.8.131.52.
