Executive Summary

CVE-2026-120348 is a code injection vulnerability in XunRuiCMS versions up to 4.7.4. It allows remote attackers to execute arbitrary PHP code by manipulating the site name in email templates. The flaw occurs in the _get_tpl_content function of Notice.php, where user-controlled input is directly substituted into template source code before compilation.

Detection Guidance

Check for suspicious PHP files in your web root, particularly files like /zz_shell.php. Inspect the site name configuration in the admin backend for encoded or unusual characters. Review cron tasks or scheduled jobs for unauthorized entries like index.php?s=api&c=run&m=index with SYS_CRON_AUTH=0.

Impact Analysis

This vulnerability allows unauthenticated attackers to remotely execute arbitrary commands on the server running XunRuiCMS. Successful exploitation could lead to complete system compromise, data theft, or installation of persistent backdoors. Attackers can gain control over the web server user account and potentially escalate privileges.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, violating GDPR's data protection requirements and HIPAA's security rules. Organizations may face regulatory fines, legal liabilities, and reputational damage if this vulnerability is exploited to access or leak sensitive data.

Mitigation Strategies

Disable anonymous task runner access by setting SYS_CRON_AUTH to a secret value. Restrict write permissions on site configuration files. Avoid direct substitution of user-controlled data into templates. Escape template control characters and disable unsafe eval-like compilation of user content.
