WBBlog "e_id" Cross-Site Scripting

Saturday, 17 March 2007

Description:
xoron has discovered a vulnerability in WBBlog, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "e_id" parameter in index.php (when "cmd" is set to "viewentry") 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 vulnerability is confirmed in version 1.0. Other versions may also be affected.

Solution:
Edit the source code to ensure that input is properly sanitised.
