CVE-2025-66292

8.1 HIGH

📋 TL;DR

CVE-2025-66292 is an arbitrary file deletion vulnerability in DPanel server management panel. Authenticated users can delete any file on the server via path traversal in the /api/common/attach/delete interface. This affects all DPanel installations prior to version 1.9.2.

💻 Affected Systems

Products:
  • DPanel
Versions: All versions prior to 1.9.2
Operating Systems: All operating systems where DPanel runs
Default Config Vulnerable: ⚠️ Yes
Notes: Requires authenticated access to the administrative backend. All default configurations are vulnerable.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise through deletion of critical system files, configuration files, or application data leading to service disruption, data loss, or privilege escalation.

🟠

Likely Case

Malicious authenticated users deleting application files, configuration files, or user data causing service disruption and data loss.

🟢

If Mitigated

Limited impact if proper file permissions restrict deletion to non-critical files, but still allows deletion of application data.

🌐 Internet-Facing: HIGH - DPanel is typically exposed to the internet for server management, making it accessible to attackers.
🏢 Internal Only: HIGH - Even internal-only deployments are vulnerable to authenticated malicious users or compromised accounts.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires authenticated access but is straightforward once credentials are obtained. The vulnerability is simple path traversal with no complex bypass techniques needed.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.9.2

Vendor Advisory: https://github.com/donknap/dpanel/security/advisories/GHSA-vh2x-fw87-4fxq

Restart Required: Yes

Instructions:

1. Backup current DPanel installation and data. 2. Download DPanel version 1.9.2 from GitHub releases. 3. Replace existing installation with new version. 4. Restart DPanel service. 5. Verify functionality.

🔧 Temporary Workarounds

Access Control Restriction

all

Restrict access to the /api/common/attach/delete endpoint using web server rules or application firewall.

# Example nginx location block to deny access
location /api/common/attach/delete {
    deny all;
    return 403;
}

File Permission Hardening

linux

Set restrictive file permissions on critical system directories to prevent deletion even if vulnerability is exploited.

# Make critical directories read-only
chmod -R 555 /etc/
chmod -R 555 /usr/
chmod -R 555 /var/log/

# Note: This may break normal system operations

🧯 If You Can't Patch

  • Implement strict access controls to limit who can authenticate to DPanel administrative interface.
  • Monitor and audit file deletion activities on the server, particularly focusing on the DPanel process.

🔍 How to Verify

Check if Vulnerable:

Check DPanel version. If version is less than 1.9.2, the system is vulnerable. Also check if /api/common/attach/delete endpoint exists and accepts path parameters.

Check Version:

Check DPanel web interface or configuration files for version information. For command line: grep -r "version" /path/to/dpanel/installation/

Verify Fix Applied:

After upgrading to 1.9.2, verify that path traversal attempts in the /api/common/attach/delete endpoint are properly rejected and no longer allow arbitrary file deletion.

📡 Detection & Monitoring

Log Indicators:

  • Unusual file deletion events in system logs
  • Multiple failed or successful DELETE requests to /api/common/attach/delete with path traversal patterns
  • DPanel logs showing file deletion operations outside expected directories

Network Indicators:

  • HTTP requests to /api/common/attach/delete containing ../ patterns
  • Unusual authentication patterns followed by file deletion requests

SIEM Query:

source="dpanel" AND (uri_path="/api/common/attach/delete" AND (request_body LIKE "%..%" OR request_body LIKE "%../%"))
