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 login..." link.
The vulnerability is confirmed in version 1.8.6. Other versions may also be affected.
Solution:
Update to version 1.8.7.
Provided and/or discovered by:
