TITLE:
oBlog Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA37661
VERIFY ADVISORY:
https://secunia.com/advisories/37661/
DESCRIPTION:
Milos Zivanovic has discovered multiple vulnerabilities in oBlog,
which can be exploited by malicious people to conduct cross-site
scripting, script insertion, and cross-site request forgery attacks.
1) Input passed to the "search" parameter in index.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.
2) Input passed via "commentName", "commentEmail", commentWeb", or
"commentText" form field in article.php (when "aid" is set to a valid
article id and "comment" is set to "new") 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
context of an affected site when the malicious data is being viewed.
3) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. to change administrative
credentials, disable published content, or conduct script insertion
attacks if a logged-in user visits a malicious web site.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
Do not browse untrusted sites or follow untrusted links while being
logged-in to the application.
