[原文]Multiple cross-site scripting vulnerabilities in PostNuke 0.760-RC3 allow remote attackers to inject arbitrary web script or HTML via the (1) module parameter to admin.php or (2) op parameter to user.php. NOTE: the vendor reports that certain issues could not be reproduced for 760 RC3, or for .750. However, the op/user.php issue exists when the pnAntiCracker setting is disabled.
PostNuke contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'module' variable upon submission to the admin.php script. 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.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.

A remote cross-site scripting vulnerability affects PostNuke. This issue is due to a failure of the application to properly sanitize user-supplied input prior to including it in dynamically generated Web content.
An attacker may leverage this issue to have arbitrary script code executed in the browser of an unsuspecting user. This may facilitate the theft of cookie-based authentication credentials as well as other attacks.
Currently we are not aware of any vendor-supplied patches for this issue. If you feel we are in error or are aware of more recent information, please mail us at: email@example.com <mailto:firstname.lastname@example.org>.
