Pavithra Hanchagaiah has discovered some vulnerabilities in PHP-Blogger, which can be exploited by malicious users to conduct script insertion attacks.

Input passed to the "title" and "description" parameters when posting news, the "Description" fields when posting a slideshow, and the "Site Name" field when updating the general preferences and installing the application isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious user data is viewed.

Successful exploitation requires access to the administration section.

The vulnerabilities have been confirmed in version 2.2.5. Other versions may also be affected.

Solution
Grant only trusted users access to the administration section.
