TITLE:
Atlassian JIRA Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA32113

VERIFY ADVISORY:
http://secunia.com/advisories/32113/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Atlassian JIRA Enterprise Edition 3.x
http://secunia.com/advisories/product/10590/

DESCRIPTION:
Thomas Pollet has discovered some vulnerabilities in Atlassian JIRA,
which can be exploited by malicious people to conduct cross-site
scripting and cross-site request forgery attacks, and by malicious
users to conduct script insertion attacks.

1) Input passed via the "Full Name" parameter when altering a user
profile is not properly sanitised before being stored. This can be
exploited to insert arbitrary HTML and script code, which is executed
in a user's browser session in context of an affected site when the
malicious profile is viewed.

Successful exploitation requires a valid user account.

2) Input passed via the "returnUrl" parameter to
"secure/AddComment!default.jspa" 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) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
request. This can be exploited to perform actions with the privileges
of a target user, who is tricked into visiting a malicious website.

The vulnerabilities are confirmed in Atlassian JIRA Enterprise
Edition version 3.13. Other versions may also be affected.

SOLUTION:
Update to version 3.13.1, which fixes vulnerabilities #1 and #2.

Do not browse untrusted sites or follow untrusted links while logged
on to the application.
