[原文]Multiple cross-site scripting (XSS) vulnerabilities in showgallery.php in PhotoPost before 4.86 allow remote attackers to inject arbitrary web script or HTML via the (1) cat, (2) si, (3) page, or (4) ppuser parameters.
PhotoPost PHP Pro showgallery.php Multiple Parameter XSS
Remote / Network Access
Loss of Integrity
PhotoPost PHP Pro contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate multiple variables upon submission to the 'showgallery.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 4.86 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
