Insanely Simple Blog 0.4/0.5 - Cross-Site Scripting

source: https://www.securityfocus.com/bid/24934/info
 
Insanely Simple Blog is prone to multiple input-validation vulnerabilities, including cross-site scripting, HTML-injection, and SQL-injection issues, because the application fails to properly sanitize user-supplied input.
 
Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, execute arbitrary script code in the context of the webserver process, steal cookie-based authentication credentials, compromise the application, obtain sensitive information, access or modify data, or exploit latent vulnerabilities in the underlying database.
 
Insanely Simple Blog 0.5 and prior versions are vulnerable.
