CVE-2020-37114: GUnet OpenEclass 1.7.3 E-learning platform - Information Disclosure

GUnet OpenEclass 1.7.3 allows unauthenticated and authenticated users to access sensitive information, including system information, application version, and other students' uploaded assessments, due to improper access controls and information disclosure flaws in various modules. Attackers can retrieve system info, version info, and view or download other users' files without proper authorization.

Security readout for executives and security teams

Plain-English summary

CVE-2020-37114 affects the old GUnet OpenEclass 1.7.3 e-learning platform. The issue can expose system details, application version information, and students’ uploaded assessments due to weak access controls. For organizations still running this legacy version, the main business risk is privacy exposure and unauthorized access to student-submitted files.

Executive priority

Prioritize if OpenEclass 1.7.3 is still used for live student coursework or exposed to the internet. The issue is not rated critical, but unauthorized access to student submissions can create privacy, trust, and compliance concerns.

Technical view

Sources describe CWE-200 information disclosure in GUnet OpenEclass 1.7.3. The CVSS 4.0 score is 5.3 with network access, low attack complexity, and low required privileges. The description also mentions unauthenticated exposure paths, while the CVSS vector lists PR:L, so access requirements should be validated locally.

Likely exposure

Exposure is likely limited to organizations still operating GUnet OpenEclass 1.7.3, especially internet-facing education portals. The affected version is from the 1.7 series and appears legacy. Modern deployments may not be affected, but version verification is necessary.

Exploitation context

A public ExploitDB entry is referenced, indicating public technical details exist. The source bundle does not show CISA KEV listing or confirmed active exploitation. Treat this as a disclosure and privacy risk requiring prompt review, not as confirmed mass exploitation.

Researcher notes

Evidence identifies GUnet OpenEclass 1.7.3 and CWE-200. Public exploit details are referenced by ExploitDB, but active exploitation is not established in the provided sources. Remediation details are not explicit, so validation should focus on version, exposure, access control behavior, and vendor-supported upgrade guidance.

Mitigation direction

  • Inventory OpenEclass deployments and identify any running version 1.7.3.
  • Check official OpenEclass guidance and changelogs for supported upgrade paths.
  • Restrict public access to legacy OpenEclass instances until reviewed.
  • Review course-file and assessment-access permissions for improper exposure.
  • Retire or isolate unsupported legacy installations where upgrades are unavailable.

Validation and detection

  • Confirm the deployed OpenEclass version from administrative or system records.
  • Verify low-privilege users cannot access other students’ uploaded assessments.
  • Check whether system and version information is exposed to unauthorized users.
  • Review web logs for unusual access to assessment files or system-information pages.
  • Compare findings against the CVE record, VulnCheck advisory, and vendor materials.
