IBM Lotus Quickr 8.0 server, and possibly QuickPlace 7.x, does not properly identify URIs containing cross-site scripting (XSS) attack strings, which allows remote attackers to inject arbitrary web script or HTML via a Calendar OpenDocument action to main.nsf with a Count parameter containing a JavaScript event in a malformed element, as demonstrated by an onload event in an IFRAME element.
Cross-site scripting (XSS) vulnerability in Lotus Quickr for i5/OS before 8.0.0.2 Hotfix 11, when anonymous access is disabled on HTTP ports, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
