DESCRIPTION:
Multiple vulnerabilities have been reported in Public Knowledge
Project Open Journal Systems, which can be exploited by malicious
users to conduct script insertion attacks and compromise a vulnerable
system and by malicious people to conduct cross-site scripting attacks
and manipulate certain data.

1) Certain input is not properly sanitised in the
"String::stripUnsafeHtml()" function within
lib/pkp/classes/core/String.inc.php before being used. This can be
exploited to insert arbitrary HTML and script code, which will be
executed in a user's browser session in context of an affected site
if malicious data is viewed.

2) Input passed via the "editor" and "callback" parameters to
lib/pkp/lib/tinymce/jscripts/tiny_mce/plugins/ibrowser/ibrowser.php
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.

3) Input passed via "articleId" when handling submissions 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 via the "param" parameter to
lib/pkp/lib/tinymce/jscripts/tiny_mce/plugins/ibrowser/scripts/rfiles.php
is not properly verified before being used to rename or delete files.
This can be exploited to rename, move, or delete arbitrary files via
directory traversal sequences and URL-encoded NULL bytes.

Note: This can further be exploited by users with "Author" role
permissions to execute arbitrary PHP code by renaming and moving an
uploaded file.

The vulnerabilities are reported in version 2.3.6. Prior versions may
also be affected.

SOLUTION:
Update to version 2.3.7.

PROVIDED AND/OR DISCOVERED BY:
1, 2, 4) High-Tech Bridge SA.
3) Reported by the vendor.
