Multiple cross-site scripting (XSS) vulnerabilities in phpWebSite 0.9.x and earlier allow remote attackers to execute arbitrary web script via (1) the day parameter in the calendar module, (2) the fatcat_id parameter in the fatcat module, (3) the PAGE_id parameter in the pagemaster module, (4) the PDA_limit parameter in the search, and (5) possibly other parameters in the calendar, fatcat, and pagemaster modules.
