[原文]Cross-site scripting (XSS) vulnerability in index.php in SugarCRM 1.X allows remote attackers to inject arbitrary web script or HTML via the (1) return_module, (2) return_action, (3) name, (4) module, or (5) record parameter.
SugarCRM contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate user-supplied input upon submission to multiple modules. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Upgrade to version 2.0.1c or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
