AI-suggested

European organizations should prioritize upgrading all instances of Dnn.Platform to version 10.1.0 or later to remediate this vulnerability. In environments where immediate patching is not feasible, organizations should implement strict input validation and output encoding policies, especially for the Prompt module commands that handle raw HTML. Employing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious script injection attempts can provide an additional protective layer. Organizations should audit user privileges to minimize the number of users with the ability to execute commands within the Prompt module, reducing the attack surface. Regular security training to raise awareness about phishing and social engineering can help mitigate risks associated with user interaction requirements. Monitoring web logs for unusual activity and implementing Content Security Policy (CSP) headers can further reduce the impact of potential XSS attacks. Finally, conducting regular security assessments and penetration testing focused on web application vulnerabilities will help identify and address similar issues proactively.

Description

DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to version 10.1.0, the Prompt module allows execution of commands that can return raw HTML. Malicious input, even if sanitized for display elsewhere, can be executed when processed through certain commands, leading to potential script execution (XSS). This issue has been patched in version 10.1.0.
