TITLE:
Joomla! Script Insertion and Cross-Site Scripting Vulnerabilities

SECUNIA ADVISORY ID:
SA35278

VERIFY ADVISORY:
http://secunia.com/advisories/35278/

DESCRIPTION:
Some vulnerabilities have been reported in Joomla!, which can be
exploited by malicious users to conduct script insertion attacks and
by malicious people to conduct cross-site scripting attacks.

1) Certain unspecified input is not properly sanitised 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 the context of
an affected site when the malicious data is displayed.

2) Certain unspecified input passed to the user view of the com_users
core component 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) Certain unspecified input passed to the "JA_Purity" template 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 Joomla! 1.5.10 and all prior
1.5.x releases.

SOLUTION:
Update to version 1.5.11.
