DESCRIPTION:
Yuri Goltsev has reported multiple vulnerabilities in Koha, which can
be exploited by malicious people to conduct cross-site scripting
attacks.

1) Input appended to the URL after opac-review.pl 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 via the "bib_list" parameter to opac-downloadcart.pl,
the "biblionumber" parameter to opac-serial-issues.pl,
opac-addbybiblionumber.pl, and opac-review.pl, and the "shelfid"
parameter to opac-sendshelf.pl and opac-downloadshelf.pl 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.

The vulnerabilities are reported in versions prior to 3.4.2.

SOLUTION:
Update to version 3.4.2 or later.

PROVIDED AND/OR DISCOVERED BY:
Yuri Goltsev, Positive Research Lab.
