The vulnerability (CVE-2025-XXXXX) in Crafter Studio arises due to improper control of dynamically-managed code resources in the Groovy Sandbox. Authenticated developers can exploit this flaw by crafting malicious Groovy scripts that bypass sandbox restrictions. The sandbox is designed to limit script execution to safe operations, but insufficient validation allows attackers to execute arbitrary OS commands. This leads to Remote Code Execution (RCE), enabling unauthorized system access, data manipulation, or further exploitation. The affected versions range from CrafterCMS 4.0.0 to 4.2.2.
DailyCVE Form:
Platform: CrafterCMS
Version: 4.0.0-4.2.2
Vulnerability: Groovy Sandbox Bypass
Severity: High
Date: Jun 19, 2025
Prediction: Patch by Jul 10, 2025
What Undercode Say:
Check Groovy script execution logs grep -r "groovy.lang" /var/log/crafter/ Verify installed version craftercms_version=$(curl -s http://localhost:8080/api/version) echo $craftercms_version Temporary mitigation (disable Groovy scripts) sed -i 's/enable_groovy_scripts=true/false/' /opt/crafter/conf/config.properties
How Exploit:
1. Authenticate as a developer.
2. Inject malicious Groovy script via CMS interface.
3. Bypass sandbox via unsafe reflection calls.
4. Execute arbitrary OS commands.
Protection from this CVE:
- Upgrade to CrafterCMS 4.3.0.
- Restrict Groovy script permissions.
- Monitor suspicious script executions.
Impact:
- Remote Code Execution (RCE).
- Unauthorized system access.
- Data compromise.
