SNS Vulnerability

ImpressCMS Multiple Vulnerabilities

Description

High-Tech Bridge SA has discovered multiple vulnerabilities in ImpressCMS, which can be exploited by malicious people to conduct cross-site scripting attacks and by malicious users to compromise a vulnerable system.
1) Input passed via the URL to notifications.php (when "del_not" is set to "1" and "delete_ok is set within a POST request) 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.
2) Input passed via the URL to modules/system/admin/images/browser.php (when "imgcat_id" is set to e.g. "1", "op" is set to "listimg", "type" is set to "ibrow", and "target" is set) 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.
3) Input passed via the URL to modules/content/admin/content.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 an affected site.
4) Input passed to the "icmsConfigPlugins[sanitizer_plugins][]" parameter in edituser.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources and execute arbitrary PHP code via e.g. a specially crafted image file with embedded PHP code.
Successful exploitation of this vulnerability requires that the "Profile" module is disabled (enabled by default) and that "magic_quotes_gpc" is disabled.
The vulnerabilities are confirmed in version 1.3 Final. Prior versions may also be affected.
