This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. 2) Input passed to the "start_date" parameter in e.g. gf/user/gforgeadmin/userfiles/my/admin/ (when "action" is set to "UsercalendarEventDelete" and "event_id" is set to a valid calendar event id) is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. Vulnerabilities #1 and #2 are confirmed in GForge Advanced Server version 6.0.0. Other versions may also be affected. 3) Input passed to the "file_id" parameter in e.g. gf/user/gforgeadmin/userfiles/my/admin/ (when "action" is set to "UserfileDelete" and "file_id" is prefixed with a valid file id) is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. 4) Input passed to the "words" parameter in gf/admin/popups/ (when "action" is set to "findusers" and "search" is set to e.g. "user_0") is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. Vulnerabilities #3 and #4 are confirmed in GForge Community Edition version 5.7.1 and GForge Advanced Server version 6.0.0. Other versions may also be affected.
