Summary

The SlimStat Analytics plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the resource parameter in all versions up to, and including, 5.2.6. This vulnerability is due to insufficient input sanitization and output escaping when logging visitor requests. It allows unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Impact

This vulnerability can have significant impacts on the security of WordPress websites using the affected SlimStat Analytics plugin. Attackers can inject malicious scripts that execute in users' browsers when they visit compromised pages. This can lead to various consequences: 1. Data theft: Attackers can steal sensitive information, including login credentials and personal data, from users who visit the affected pages. 2. Session hijacking: The injected scripts can capture user session tokens, allowing attackers to impersonate legitimate users. 3. Phishing attacks: Malicious scripts can modify page content to trick users into revealing sensitive information or redirecting them to malicious sites. 4. Malware distribution: The XSS vulnerability can be used to distribute malware to visitors of the affected website. 5. Reputational damage: If exploited, this vulnerability can harm the reputation of the affected website and potentially lead to loss of user trust. The severity of this vulnerability is heightened by the fact that it requires no user interaction and can be exploited by unauthenticated attackers, making it relatively easy to exploit.

Exploitation

There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.

Patch

A patch is available. Website administrators should update the SlimStat Analytics plugin to a version newer than 5.2.6, which addresses this vulnerability.

Mitigation

To mitigate this vulnerability, the following steps are recommended: 1. Update immediately: Upgrade the SlimStat Analytics plugin to the latest version (after 5.2.6) as soon as possible. 2. Implement Content Security Policy (CSP): Use CSP headers to restrict the execution of scripts from untrusted sources. 3. Input validation: Implement strong input validation and sanitization for all user inputs, especially the 'resource' parameter. 4. Output encoding: Ensure proper output encoding is in place for all dynamic content. 5. Regular security audits: Conduct regular security audits of your WordPress installation and all installed plugins. 6. Use Web Application Firewall (WAF): Implement a WAF to help detect and block XSS attempts. 7. Principle of least privilege: Limit user permissions to reduce the potential impact of successful attacks. 8. Monitor for suspicious activity: Regularly check logs for any signs of attempted XSS attacks or unusual behavior. 9. Educate users: Train website administrators and content managers about the risks of XSS and safe practices. 10. Consider alternative plugins: If an update is not immediately available, consider temporarily disabling the plugin or switching to a secure alternative.
