CVE-2020-37115: GUnet OpenEclass 1.7.3 E-learning platform - Plaintext Password Storage

GUnet OpenEclass 1.7.3 stores user credentials in plaintext, allowing administrators to view all registered users' usernames and passwords without encryption. This vulnerability exposes sensitive information and increases the risk of credential theft and unauthorized access.

Security readout for executives and security teams

Plain-English summary

GUnet OpenEclass 1.7.3 reportedly stores user passwords in plaintext. Anyone with administrator-level access can view registered users’ usernames and passwords, creating risk of credential theft and password reuse attacks against other systems. This is most urgent for organizations still running the very old 2007-era 1.7.3 release.

Executive priority

Prioritize if OpenEclass 1.7.3 is internet-facing, used by many users, or tied to institutional credentials. Treat as lower priority if the product is not present. Because password reuse can expand impact beyond the platform, remediation should include credential hygiene, not only software cleanup.

Technical view

CVE-2020-37115 is a CWE-256 plaintext password storage issue in GUnet OpenEclass 1.7.3. The provided CVSS 4.0 score is 7.1, with network attack vector and low privileges required. Sources indicate administrator access can expose all registered user credentials. A public ExploitDB entry exists, but the bundle does not show CISA KEV listing or confirmed active exploitation.

Likely exposure

Exposure is likely limited to environments still operating GUnet OpenEclass 1.7.3. The main business risk is disclosure of user credentials by any administrator or compromised administrator account, with downstream risk where users reused passwords on email, LMS, VPN, or institutional services.

Exploitation context

A public ExploitDB reference is listed, indicating public technical disclosure. However, the provided sources do not establish active exploitation in the wild, and the CVE is not marked KEV. Exploitation requires at least low privileges, described as administrator visibility of stored credentials.

Researcher notes

The source bundle identifies only GUnet OpenEclass 1.7.3 as affected. It does not provide a specific fixed version. The changelog is referenced as a patch-related source, but remediation details should be verified directly with vendor documentation before making version-specific claims.

Mitigation direction

  • Identify and decommission or upgrade any GUnet OpenEclass 1.7.3 deployments.
  • Review vendor site and changelog for supported versions and remediation guidance.
  • Restrict administrator access to trusted personnel only.
  • Rotate OpenEclass passwords after remediation.
  • Consider rotating passwords on other systems if reuse is plausible.

Validation and detection

  • Inventory web applications for GUnet OpenEclass 1.7.3.
  • Confirm version through approved administrative or asset-management methods.
  • Review whether stored user passwords are plaintext in the affected deployment.
  • Audit administrator accounts and recent administrative access.
  • Verify password rotation occurred after migration or remediation.
