TITLE:
Interspire ArticleLive 2005 Cross-Site Scripting and Security Bypass

SECUNIA ADVISORY ID:
SA15250

VERIFY ADVISORY:
http://secunia.com/advisories/15250/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Cross Site Scripting, Exposure of system information

WHERE:
>From remote

SOFTWARE:
Interspire ArticleLive 2005
http://secunia.com/product/4834/

DESCRIPTION:
Diabolic Crab has reported two vulnerabilities in Interspire
ArticleLive 2005, which can be exploited by malicious people to
conduct cross-site scripting attacks and bypass certain security
restrictions.

1) Input passed to the "BlogId" parameter in "newcomment/" isn't
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 a vulnerable site.

2) The problem is that the authentication process can be bypassed by
manually setting the "auth" and "userId" cookie parameters. This can
be exploited to gain administrative privileges.

It is also possible to disclose the full path to "search" by
accessing it with an invalid "Query" parameter.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
that authentication is properly performed.
