Missing Content Security Policy in Beghelli Sicuro24 Enables Remote Script Injection

Executive Summary

Beghelli Sicuro24 SicuroWeb does not enforce a Content Security Policy (CSP), which normally restricts the loading of external JavaScript resources.

Because there is no CSP, attackers can load external scripts from attacker-controlled origins.

When this lack of CSP is combined with other vulnerabilities in the same application, such as template injection and sandbox escape, attackers can execute arbitrary remote code in the operator's browser session.

Detection Guidance

This vulnerability arises from the absence of a Content Security Policy (CSP) in the Beghelli Sicuro24 SicuroWeb application, allowing unrestricted loading of external JavaScript resources.

To detect this vulnerability on your system, you can inspect the HTTP response headers of the SicuroWeb web interface to check if a Content-Security-Policy header is present.

• Use curl to fetch headers: curl -I https://<sicuroweb-host>/
• Look for the absence of the Content-Security-Policy header in the response.

Additionally, you can use browser developer tools to inspect loaded scripts and verify if external scripts from untrusted origins are being loaded.

Impact Analysis

This vulnerability allows attackers to execute arbitrary JavaScript code in the context of the operator's browser session.

Such code execution can lead to unauthorized actions, data theft, session hijacking, or further compromise of the application environment.

Compliance Impact

The vulnerability in Beghelli Sicuro24 SicuroWeb involves the absence of a Content Security Policy (CSP), which allows attackers to load and execute arbitrary external scripts in operator browser sessions. This can lead to unauthorized access or manipulation of sensitive data handled by the application.

Such unauthorized script execution and potential data compromise could negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require adequate protection of personal and sensitive information against unauthorized access and breaches.

However, the provided information does not explicitly state the direct impact on compliance with these standards.

Mitigation Strategies

To mitigate this vulnerability, you should enforce a Content Security Policy (CSP) on the Beghelli Sicuro24 SicuroWeb application. Implementing a strict CSP will restrict the loading of external JavaScript resources, preventing attackers from injecting arbitrary remote scripts.

Additionally, addressing the related template injection and sandbox escape vulnerabilities in the application will further reduce the risk of exploitation.
