System and student file disclosure via exposed paths

Published Feb 3, 2026 · Updated Feb 3, 2026

Information exposure in GUnet Open eClass 1.7.3 allows remote attackers to read system, version, and student assessment data. Public routes expose phpSysInfo and application-version files, while course work directories permit students to list and download peers' uploads. System and version details require no account; assessment access requires a student account and an exposed directory listing, with no reported write or service-interruption impact.
