[原文]Multiple cross-site scripting (XSS) vulnerabilities in PHPFreeNews 1.40 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) NewsMode parameter to NewsCategoryForm.php, or the (2) Match or (3) NewsMode parameter to SearchResults.php.
PHPFreeNews contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'NewsMode' variable upon submission to the NewsCategoryForm.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.
Upgrade to version 1.41 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
