CVE-2018-20159: i-doit open 1.11.2 allows Remote Code Execution because ZIP archives are mishandled.

i-doit open 1.11.2 allows Remote Code Execution because ZIP archives are mishandled. It has an upload feature that allows an authenticated user with the administrator role to upload arbitrary files to the main website directory. Exploitation involves uploading a ".php" file within a ".zip" file because a ZIP archive is accepted by /admin/?req=modules&action=add as a plugin, and extracted to the main directory. In order for the ".zip" file to be accepted, it must also contain a package.json file.

Security readout for executives and security teams

Plain-English summary

This issue lets an authenticated administrator turn a plugin archive upload into remote code execution on i-doit open 1.11.2. Business risk is highest where the admin interface is exposed or admin accounts are weakly controlled. The provided sources do not show active exploitation.

Executive priority

Prioritize remediation for any exposed i-doit open 1.11.2 instance. The impact is potentially full application compromise, but exploitation requires administrator-level access according to the provided description.

Technical view

The vulnerability is improper handling of ZIP-based plugin uploads. A crafted archive accepted as a plugin can be extracted into the main website directory, allowing server-side executable content to run. The source bundle identifies i-doit open 1.11.2, but provides no CVSS, CWE, or broader affected-version data.

Likely exposure

Exposure appears limited to i-doit open 1.11.2 instances where an authenticated administrator can access plugin upload functionality. Internet-facing admin panels, shared administrator accounts, or compromised admin credentials materially increase risk.

Exploitation context

Public exploit references are listed, including Exploit-DB, but the CVE is not marked in KEV. Based on the provided sources, treat exploit knowledge as public, but do not claim confirmed active exploitation.

Researcher notes

Key unknowns are CVSS score, CWE classification, fixed release, and affected version range beyond 1.11.2. Avoid assuming unauthenticated reachability; the source states administrator authentication is required.

Mitigation direction

  • Check i-doit vendor guidance for fixed versions or official mitigations.
  • Restrict administrator interface access to trusted networks and users.
  • Disable or tightly control plugin upload functionality where feasible.
  • Review administrator accounts, MFA, and least-privilege access controls.
  • Monitor the web directory for unexpected executable files.
  • Review logs for suspicious plugin or archive upload activity.

Validation and detection

  • Inventory i-doit open deployments and confirm exact version.
  • Confirm whether plugin upload is reachable by administrator users.
  • Review web directories for unexpected files created after archive uploads.
  • Check application and web server logs for plugin upload events.
  • Verify administrator accounts are legitimate and recently reviewed.
