DESCRIPTION:
Sony has discovered multiple vulnerabilities in GForge Community
Edition and Advanced Server, which can be exploited by malicious
people to conduct cross-site scripting attacks.

1) Input passed to the "id" parameter in e.g.
gf/user/gforgeadmin/userfiles/my/admin/ (when "action" is set to
"UserblogDelete" and "id" is prefixed with a valid blog post 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.

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.

SOLUTION:
Filter malicious characters and character sequences using a proxy.
