Laurent Gaffié and Benjamin Mossé have reported some vulnerabilities in BlogMe, which can be exploited by malicious people to conduct script insertion and SQL injection attacks.
1) Input passed to the "name", "url", and "comments" form field parameters in comments.asp 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 comment is viewed.
2) Input passed to the "Username" and "Password" form fields in admin_login.asp is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The vulnerabilities are reported in version 3.0. Other versions may also be affected.
Solution: Edit the source code to ensure that input is properly sanitised.
