VERIFY ADVISORY:
http://secunia.com/advisories/23656/
CRITICAL:
Not critical
IMPACT:
Cross Site Scripting
WHERE:
>From remote
SOFTWARE:
b2evolution 1.x
http://secunia.com/product/12768/
DESCRIPTION:
unsticky has discovered a vulnerability in b2evolution, which can be
exploited by malicious people to conduct cross-site scripting
attacks.
Input passed to the "redirect_to" parameter in htsrv/login.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.
Successful exploitation allows adding additional attributes (e.g.
"onMouseOver") to the "Bypass loginβ¦" link.
The vulnerability is confirmed in version 1.8.6. Other versions may
also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
