[原文]Multiple cross-site scripting (XSS) vulnerabilities in SitePanel 2.6.1 and earlier (SitePanel2) allows remote attackers to inject arbitrary web script or HTML via (1) the v, show, or sec_name parameters to main.php, (2) the inadmin, newsev, or postid parameters to 5.php, or (3) the id parameter to 0.php.
SitePanel2 contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'v', 'show' or 'sec_name' variables upon submission to the main.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 18.104.22.168 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
