Authenticated system-file disclosure via directory listing
Published Feb 24, 2021 · Updated Aug 3, 2024
Directory listing in CONTEC SolarView Compact SV-CPT-MC310 before 6.5 allows remote authenticated users to read system files. The embedded web interface returns directory indexes containing directory names and file configurations instead of denying enumeration; the affected endpoint is undisclosed. An account and adjacent-network access are required, and the reported consequence is read-only disclosure with no integrity or availability impact.
