[原文]Cross-site scripting (XSS) vulnerability in viewtopic.php in Xoops 2.x, possibly 2 through 2.0.5, allows remote attackers to inject arbitrary web script or HTML via the (1) forum and (2) topic_id parameters.
It has been reported that Xoops may be prone to a cross-site scripting vulnerability that may allow a remote user to execute HTML or script code in a user's browser. HTML and script code may be parsed via the 'topic_id' and 'forum' URI parameters of 'newbb/viewtopic.php' script.
Successful exploitation of this attack may allow an attacker to steal cookie-based authentication credentials. Other attacks are also possible.
Xoops versions 2.x have been reported to be prone to this issue.
